 FERMENTATION

Combining modern process technology and traditional sour fermented beverages Non-alcoholic fermented beverages have enjoyed increasing popularity for years, which has led to a steady expansion of the product range. Sweetened soft drinks have long lost their appeal, in favor of alternatives with lower sugar content. These include, among others, sour fermented beverages such as kombucha and water kefir.

Stefanie Malchow, Jakub Borowski, Martin Senz, all Department for Bioprocess Engineering and Applied Microbiology (BEAM), Research Institute for Biotechnology and Water (FIBW), Versuchs- und Lehranstalt für Brauerei in Berlin (VLB) e.V. Traditional, sour fermented drinks are characterized by a pleasant acidity, which together with a low sugar content and an interesting variety of aromas, provide for a very refreshing character.

In addition, these beverages are often attributed health benefits due to their ingredients, which has a positive impact on demand.

The increasing popularity of such traditional beverages often requires a rethinking on the part of producers, moving away from the tradi-

tional process towards a reproducible process that also ensures product safety and minimizes batch variability.

Thus, a comprehensive understanding of the fermentation process is needed, which can be adequately characterized and controlled through the use of analytical and process engineering methods.

Water kefir and kombucha Traditional, sour fermented beverages have one thing in common in classic pro-

duction: they are obtained through the use of complex (mostly) undefined mixed cultures. This represents the greatest hurdle, both in terms of process engineering and in terms of production on an industrial scale.

Among other things, complex cultures are characterized by the fact that the microorganisms involved are present in undefined proportions, the composition being subject to considerable changes over time. In addition, the microorganisms often form

Represented are A: relevant sugars and metabolites, B: the antioxidant capacity as well as the redox potential, C: the suspended cell concentrations of yeasts and lactic acid bacteria and their contained cfu, and D: the dissolved oxygen (DO) and the change in the atmospheric composition in the headspace of the (non-aerated) bioreactor recorded up to 72 h exopolysaccharides, which are colonized by the organisms and have a positive effect on the specific metabolic performance during fermentation. Traditionally, water kefir is made from sweetened water, dried fruit and the so-called water kefir grains (Fig. 1A). The latter, depending on the origin and age of the cultures, harbor different lactic acid bacteria and yeasts, often Lactobacillus paracasei, L. hilgardii and L. nagelii and Saccharomyces spp. and Brettanomyces spp., respectively. Over a fermentation period of usually 2–4 days at room temperature, the organisms form CO2, organic acids (especially lactic acid), glycerol, small

8

amounts of ethanol and various aroma components, which give the fermented product a fruitysweet and refreshing character.

Typically, water kefir is considered a non-alcoholic drink, primarily due to the short fermentation time.

In the traditional production of kombucha, sweetened tea is fermented with the so-called SCOBY (symbiotic culture of bacteria and yeasts; Fig. 1B) for several days to weeks at room temperature.

In addition to CO2, organic acids (mainly acetic acid), glycerol and aroma components, as well as small amounts of ethanol, are formed along with CO2. The SCOBY, as the name suggests, is

Brauerei Forum International – May 2019

composed of yeasts and bacteria, and depending on their origin and age, Brettanomyces spp. and Zygosaccharomyces spp. dominate in the yeasts as well as Acetobacter spp., Gluconobacter spp. and Gluconoacetobacter spp. in the bacteria. Kombucha is also considered a non-alcoholic fermentation drink, although ethanol is formed during fermentation by the yeasts. However, it is metabolized by the acetic acid bacteria in the course of the production process to acetic acid, so that the ethanol content is usually less than 0.5 %vol.

Compared to the traditional production, industrial production focuses on aspects such as

quality assurance and product safety, with traditional aspects such as taste and naturalness being of great importance to the consumer.

When adapting the manufacturing process for the industrial scale, it is therefore important to meet customer and quality requirements at the same time through indepth process knowledge and improved procedures.

From a microbiological point of view, the first step is to exchange traditional cultures for defined pure cultures.

This reduces the risk of contamination and increases the controllability on an industrial scale at an early stage. By using such starter cultures, producers can also target desired product properties, such as the acid spectrum or flavor profile.

Also other ingredients such as sugar or dried fruit, which serve as nutrients to the organisms during fermentation, should be added to the process in a well-defined manner. In addition to defined ingredients, comprehensive process-accompanying analysis contributes to a secure process through its use as controller.

Exemplary course of a water kefir fermentation For the development of a secure process, the general conditions must first be comprehensively determined. In the course of development work on the production of water kefir, the characteristic temporal course of a traditional fermentation with undefined starter cultures was therefore identified (Fig. 2).

The sugar profile as well as the production of acid and ethanol during the fermentation process were determined by means of HPLC analyses (Fig. 2A). The interaction of the sucrose cleavage caused by the microorganisms and the resulting release of glucose and fructose was clearly demonstrated, the latter being degraded at a lower rate than glucose.

At the same time, continuous ethanol formation was observed, whereas lactic acid formation due to lactic acid bacteria stagnated after 72 h. Due to the metabolic activities, rapid consumption of dissolved oxygen and a drop in pH were observed (Fig. 2B). The redox potential was also lowered during fermentation by the microorganisms, while the antioxidative capacity increased (Fig. 2C). Exhaust gas analysis was used to determine the atmosphere in the headspace. During the first 72 h, a saturation with CO2 was observed with simultaneous reduction of the oxygen content. In addition, the redox potential reached after 48 h showed good conformity with the desired sensory properties and an alcohol content of less than 0.5 %vol. required for the declaration "non-alcoholic". On the basis of the data collected, further investigations are to show how the mentioned parameters behave when using defined starter cultures and whether a suitable fermentation profile can be reproduced by suitable process control.

Further modern techniques available for the development of fermentation processes are those for analyzing the growth characteristics of the respective microorganisms. Thus, with the aid of impedance measurement methods, a statistically meaningful concentration determination can be carried out, which can be used to distinguish between different populations such as yeasts and bacteria by simultaneously determining the cell size distribution. Due to the multitude of available markers, flow cytometric methods offer the possibility to make additional statements on physiology on the basis of individual cells. For the analysis of rod-shaped lactic and acetic acid bacteria, electro-optical methods can be applied to quantify

For the illustrated process using complex cultures, such analysis technologies can only be applied with reservations. In addition to the static fermentation, the secreted exopolysaccharides complicate the microbiological analyses. The development of suitable microbiological analytical methods requires special attention when using complex mixed

cultures. Due to the particle size, which spreads over the entire size range of the bacteria and yeasts and additionally provides for a turbidity of the medium, the data of the optical methods and the impedance measurement for the fermentation process shown in Fig. 2 were unusable. Furthermore, it should be noted that due to the inhomogeneous distribution of the microorganisms present in the grains and in the liquid, representative sampling of the overall batch is not possible. Accordingly, the classical

cell count of the cells in suspension was resorted to using the Thoma cell count chamber, which allows a good manual differentiation of the yeasts and bacteria, as well as the determination of colony-forming units by plating on selective nutrient media (Fig. 2D). For further development, pure cultures isolated from water kefir grains should be used after they have been analyzed and well-characterized.

In the case of tea-based traditional kombucha there are characteristic differences in the microbiology involved. Nevertheless, the challenges for an industrial manufacturing process and adequate storage stability, especially if the consumer's desire for an unpasteurised product is to be pursued, are very similar.

By applying extensive analysis methods, the complete manufacturing process up to the bottled product can be tracked. In-depth process knowledge also makes it possible to respond adequately to the many challenges, especially with unprocessed products.

An important quality criterion is the sensory evaluation of the fermented product along its entire life cycle. Last but not least, this aspect also determines the shelf life as well as consumer acceptance of the product.

Berliner Weisse

A traditional beer through the ages – part 1: How has the character of Berliner Weisse changed?

In the 19th century, Berliner Weisse could be found all over Berlin. However in the last few decades, it has been reduced to a niche existence. Recently, craft brewers around the world have rediscovered this traditional style of beer. In the first part of his article, the author focuses on the original composition of the fermentation cultures and on the question of how the hygienic conditions from more than 100 years ago influenced the flavor of this sour beer.

Dr. Peter Lietz

Brewers around the world are vying to revive the ‘original’ Berliner Weisse, which hit the peak of its popularity toward the end of the 19th and the beginning of the 20th century. Of course, the question is: What did Berliner Weisse actually taste like back then? Was there even a specific method for producing it? No samples remain from this era, so we are forced to draw our conclusions about the flavor based on contemporary sources.

The numerous studies conducted and published in the early 20 th century by VLB Berlin under the auspices of Franz Schönfeld (1866– 1940) indicate that in addition to the quality of the pitching yeast mixed with lactic acid bacteria, the specific local conditions of the respective brewery had a decisive impact on the quality of the Berliner Weisse produced. This included the wooden tools that were common at the time, the open cooling systems, and also the poorly devel-

oped state of cleaning technology during the period.

In December 1907, Schönfeld held a lecture for bartenders who served weiss beer. In it, he described the Berliner Weisse of the early 20 th century as follows: “It should be clear, with a nice lasting head after pouring; it should taste pleasantly tart and wine-like, with a fine bouquet and heavy carbonation.” In the same piece published in 1908 in the Wochenschrift für Brauerei weekly brewery journal, he added: “But as everywhere, there are so many exceptions when it comes to weiss beer that these exceptions often outnumber the rule.” This statement makes one thing clear: In the heyday of this classic beer, there wasn’t just one weiss beer; there were many different versions of it.

beer at the time was that the breweries would deliver the young beer to the bars shortly after it was produced. The fermentation process would then be completed in the cellars of the bars, and the bar

tenders would bottle the young beer themselves – often adding water to it. Over the years, the hygienic conditions in both the breweries and the bars formed different ‘communities’ of microbes in the beer as it aged. These blends of microbial cultures must have had a significant influence on the aroma and acidity of the beer, particularly when the beer was stored for a year or longer. Generally, that influence was positive, but it could also have been negative in some cases. Another special characteristic of this sour, top fermented beer is that it was not brewed according to Emil Christian Hansen’s (1842–1909) rules of pure fermentation, but rather according to the principles of ‘natural pure culture’ developed by Max Delbrück (1850–1919). Consequently, it was not implausible that unwanted microorganisms would gain the upper hand in this mixed fermentation process, potentially causing the beer to spoil. Today, when we talk about the ‘original’ Berliner Weisse, we should keep in mind that there must have been a number of very different versions of this beer, with different aromas and levels of acidity.

Traditional craft brewing was less than hygienic Not only were many recipes and the extensive knowledge of the brewmasters lost with the closure

of countless small weiss beer breweries in the late 19th century, it is particularly unfortunate from a present-day perspective that numerous special microorganisms were also irrevocably lost along with those breweries. According to Schönfeld’s accounts, these mixed microbial cultures were very difficult to control. Mixed microbial cultures generally separate again quite quickly, regardless of whether the cultures are of the same genus or different species; this is due to the varying generation times of the microorganisms involved.

Additionally, the breweries' equipment – generally consis t ing of untreated tuns, bar rel s , and tools made of wood – had a significant influence on the development of these mixed populations of microorganisms.

Paul Lindner made this point in an article he wrote for the Wochenschrift für Brauerei back in 1900. “Those who are knowledgeable about the anatomy of wood will immediately recognize that the wide wooden

Brauerei Forum International – May 2019

– and often numerous – conduits present in all breweries are very well suited to serve as a lair for all manner of microbes.” Lindner also pointed out the many sources of contamination in the breweries at the turn of the 20 th century.

We know today that biofilms composed of a broad range of different microorganisms are formed in the pores of the wood. These microorganisms are capable of exchanging metabolites and gene sequences among one another. In that sense, the wooden tools and barrels used in weiss beer breweries in the 19th and early 20 th centuries offered ideal conditions for a range of different weiss beer cultures to grow.

Additionally, in the 18th century, it was rumored that some brewers of weiss beer in Berlin eschewed well water in favor of the likely highly polluted water from the local River Spree. This is a further indicator that people at the time were unaware of how important the microflora were to the quality of the beer.

Development of Berlin-style weiss beer in the era of pure fermentation Naturally, the brewers at the end of the 18th century already knew about the importance of cleaning to the beer production process.

However, it was not yet possible for them to combat unwanted microbes or biofilms with the cleaning tools available to them at the time such as water and brushes, let alone to disinfec t t heir equipment.

The longer a batch of beer was stored in (contaminated) wooden barrels, the easier it was for bacteria, such as the S arc ina bacteria that brewers of weiss beer particularly feared, to grow. This could lead to the beer becoming ‘ropy’, which meant that it developed a slimy consistency. Other bacteria would lend the beer an obvious

diacetyl ‘buttery’ flavor or an unpleasant acidic note.

The ‘original’ Berliner Weisse of the late 19th century disappeared from the market with the closure of the original weiss beer breweries and the associated departure from traditional craft brewing and with the movement toward modern brewing in facilities designed for optimum hygiene. Returning to traditional brewing methods with wooden barrels and unchecked microbial cultures would be a dangerous game with unpredictable financial risks.

Rather, modern brewers who want to revive this interesting beverage would be well advised to draw on the experience and insight of past brewmasters and scientists, discussed at many October Conventions and documented in VLB Berlin’s weekly journals from the late 19th and early 20 th centuries. Brewing top fermented beers based on the original Berliner Weisse requires special top fermenting cultured yeasts that are also capable of fermenting dextrins with lower molecular weight. However, more research is needed here in order to cultivate these special types of yeast.

Any potential research would need to place particular focus on selecting the appropriate lactic acid bacteria. Top fermented cultured yeasts and lactic acid cultures should be kept separate as pure cultures. The young beers should be blended together at the end of the process to achieve the desired acidity and aroma. Pasteurizing the lactic acid component before blending will help to prevent uncontrolled acidification after the fact. Only a relatively small number of 19 th century weiss beer organisms still exist today, so it would be advisable to first search through the collection of available cultures, then to focus on isolating productive strains. It certainly would not be wise to replace Saccharomyces cerevisiae with a wild

strain of Brettanomyces yeast as a culture. If the intention is to create entirely new flavors, it might be worth considering a selection of special secondary fermentation yeasts with individual cultures from the Brettanomyces (B. bruxellensis, B. brevis, B. claussenii) and Hansenula genera.

Brewers could also fall back on other types of yeast that are known to produce stronger flavor substances. The important thing is that the cultures have a stable range of by-products and can be cultivated separately, and that the fermented product is pasteurized before it is added to the beer base. Breweries that would like to add a ‘Berlin-style weiss beer’ to their product range should look for a selection of special malt varieties. Above all, however, the brewing process should involve productive weiss beer cultures with their own ‘Berlinstyle weiss beer’ flavor, possibly also with a slight hint of acidity.

If brewers can ensure consistent quality, they will be rewarded with loyal, grateful customers.

The second part of this article will focus on the microorganisms that were likely involved in the production of Berliner Weisse in the past.

It will appear in our next international issue in November 2019.

Comprehensive information on this subject is available in the book "Die Berliner Weisse – Ein Stück Berliner Geschichte" (‘Berliner Weisse – A Piece of Berlin History’), published by VLB and written by Gerolf Annemüller, Hans-J. Manger, and Peter Lietz.

Other activities Further international seminars are scheduled in addition to these four major conferences. In collabo­ ration with Beviale Family (NürnbergMesse), VLB has been or will be taking part in seminars/workshops being held in Moscow, Milan, Shanghai, Chile, Bangalore, and Nuremberg this year. And lest we forget, there are also international training semi­nars, including the VLB Certified Brewmaster Course, Craft Brewing in Practice, Micro Malting in Practice, and Applied Microbiology, held each year in Berlin.

“We have been successfully pur­ suing a strategy of internation­ alizing our service portfolio for more than 15 years,” says VLB Managing Director Dr. Josef Fontaine.

“In this time we’ve been able to add a large number of new members and customers from around the globe. Our international events are an important communication tool, especially for brewers in the emerging market countries in Asia, Africa, and South America. At this point, we would also like to thank our colleagues in the supplier industry who actively support these projects.”

 TRADE FAIRS

VLB was part of Beviale Family events in Moscow and Milan This year, two trade fairs have already been held by Beviale Family, NürnbergMesse, in which VLB Berlin participated as a cooperation partner. In February, the VLB seminar "Modern Brewing Technologies" took place parallel to Beviale Moscow for the fourth time. And in March, the second edition of Craft Beer Italy, a joint project by NürnbergMesse Italia, Doemens and VLB, was held in Milan.

(F./BF) From 19 to 21 February 2019, Beviale Moscow offered players from the Eastern European beverage industry a central platform at Moscow's Crocus Expo.

Around 6200 trade visitors (some 5300 in 2018) from 47 countries were in good spirits and showed a keen interest in the 164 exhibitors (146 in 2018). The trade fair for the beverage industry pursues a holistic approach and covers the entire process chain from manufacturing to marketing.

Following the successful event, Thimo Holst, Project Manager Beviale Moscow, voiced his satisfaction: "With this fourth round, Beviale Moscow has once again taken a signifacant step forward.

It has grown even more and is bigger than ever this year." But it is not just the size that matters. “We are

delighted that despite the somewhat more difficult market conditions, more and more exhibitors are recognising and wanting to tap into the significant, undisputed potential of the Russian and Eastern European beverage industry.”

This was also reflected in the many exhibition stands displaying numerous exhibits and in some cases large installations. “The good mood at the venue underscores the positive and connective nature of Beviale Moscow,” added Holst.

Some 97 percent of the exhibitors polled were satisfied with their participation in the event.

program included 16 highly interesting lectures focusing on handcrafted beer and specific technological and qualitative aspects of the brewing process. On the first day, the attendees were also invited to a plant visit at Seven Hills Brewing Co. Next year, Beviale Moscow will take place at Moscow’s Sokolniki Exhibition and Convention Centre from 24 to 26 March. The VLB seminar "Modern Brewing Technology" will be held again parallel to the trade fair.

Craft Beer Italy in Milan 74 suppliers of raw materials, technologies, packaging and marketing from 12 countries (2017: 54 from 9 countries) and more than 900 visitors (2017: 670) reached MiCo Lab Fiera Milano Congressi in the

At the VLB booth, the speakers were also available after the lectures for questions.

In addition, many visitors were interested in the VLB's training and further education program as well as the various service and analysis offers of the VLB and came to the stand to find out more about it.

The four "Taste it!" areas were fully booked as well.

They represented a pleasant stop between a meeting in the exhibition area and the conference. Last but not least, Craft Beer Italy 2019 hosted the first edition of the Best Craft Beer Label Contest as well as the final stage of the Italian Championship of Beer Sommeliers Doemens.

TRAINING & EVENTS

106th Brewing and Engineering Conference – a German-French cooperation From 11 to 13 March 2019, the 106th Brewing and Engineering Conference attracted around 270 brewery experts to the Europa-Park Rust in south­western Germany. In addition to the topics on yeast management, brewing technology, bottling and wastewater treatment, a technical visit to the Brasserie Kronenbourg, located in the Alsatian town of Obernai in the neighboring France, was a highlight of the event.

1 exhibition and a get-together in the foyer of the Confertainment Center completed the event.

In the session about yeast management, Zoran Gojkovic and Surinder Singh from the Carlsberg Group presented their visions of the future of yeast development. The focus of research are the production of alternative brewing organisms, non-conventional yeasts, a new generation of cider yeast and the rapid reduction of the diacetyl content during fermentation.

Microplastics in beverages was another focus of the conference.

Microplastic as a decay product of plastic material increasingly affects our environment. Meanwhile, microplastic was also detected in

beer and beverages. Daniel Schock, Deutscher Brauer-Bund, and Dr. Nils Rettberg, VLB, outlined the current state of knowledge and analytics.

The session was supplemented by Photos: 1 – The talks were presented in a fixed circus tent at the Europa-Park Rust 2- Speakers of the opening panel: Helmut Kühnl (Esau & Hueber), Zoran Gojkovic, Surinder Singh (Carlsberg), and Dr. Martin Hageböck (VLB) (f.l.t.r.)

(oh) 16 high-profile lectures, an attractive supporting program, and a visit to the Brasserie Kronenbourg – that is a brief summary of the recent VLB Spring Meeting held from 11 to 13 March 2019 in Rust, Germany.

The event attracted 270 participants from more than 20 countries.

The venue was quite special this year: The Europa-Park Rust, located in southwest Germany directly at the river Rhine, is considered one of the largest theme parks in Europe.

The VLB conference took place in the unusual ambience of the “Confertainment Center” which is part of the Europa-Park. Between historic carousels and circus tents, the approximately 270 participants of the event felt visibly well. A trade

the lecture of Dr. Stefan Kunerth, who introduced Coca Cola's efforts to reduce plastic packaging as part of a circular economy concept.

In the technology session, Ziemann Holvrieka presented the latest practical results with the new Omnium brewhouse system.

Visit to Kronenbourg A highlight of the supporting program was a visit to the Brasserie Kronenbourg in the neighboring France. The brewery, which belongs to the Carlsberg Group, produces about 7 million hl of beer at the Obernai site, making it the largest Carlsberg brewery in France and the second largest in Europe after St. Petersburg in Russia. Today, around 800 employees work on 70 hectares. Kronenbourg has three brewhouses with a daily brewing capacity of 30,000 hl. Michael Jakob, Vice President Global Group New Technologies at Carlsberg, and Stéphane Munch, Vice President Production Obernai, are particularly proud of the fully automated bottling plants with a throughput of 30,000 hl per day. As the beer brewed in Obernai is exported to more than 80 countries, logistics is a big issue. Not least for this reason, Carlsberg will invest in a new truck loading station over the next two to three years as part of a long-term development plan. In addition, significant investments for a new bottling plant and modernized brewery technology in Obernai are announced.

After the interesting brewery tour, the evening at the Brasserie Le Tigre in Strasbourg ended with Alsatian specialities and craft beers.

On the second day, the lectures cov-

ered trends in beer and beverage bottling. In addition to microbially induced corrosion, preventative maintenance, the prevention and detection of particles in bottled bottles were discussed.

The final session focused on wastewater treatment. In addition to the report on the current status of "Best Available Techniques (BAT)", the Hall & Woodhouse Brewery (UK) presented their practical experience with a new generation of an-

aerobic wastewater treatment plant technology. Finally, a presentation about treatment of caustic from the bottle washing machine discussed the issues caused by synthetic label glues in bottle washing.

The VLB Berlin thanks all supporters of its 106th Brewing and Engineering Conference 2019 in Rust, especially the Carlsberg Group, KHS and Esau & Hueber.
