Identification Guide of Grapevines Grown in a Cold Climate — Wine grapes – 2011

Preface V

his document consists of an initial collection of information on cultivar identification and the specific viticultural characteristics of grape varieties grown in cold climates; more specifically, those that are found in the province of Québec. We propose here an ampelographic description based on our field observations in recent years. To this end, we have selected a set of morphological descriptors that are presented in the form of description sheets. These descriptors are based on those developed by the International Organization of Vine and Wine (OIV) and those of Pierre Galet, an agronomist recognized as a specialist in the field of ampelography. We also developed our own descriptors to gather as much information as possible about growing these grape varieties in Québec. To understand the concept of the descriptors and cultural characteristics, each of them are defined at the beginning of this document. These definitions, in addition to some diagrams and measurement scales, guide the readers in their own observations, and describe at the same time the methods we used to obtain our information. The description sheets are supplemented by three other sections in the book. The first part presents some characteristics of the Vitis species used in the crosses that have produced the varieties found in Québec (Vitis vinifera, Vitis labrusca, Vitis riparia, etc.). Knowing the parents of a grape variety can provide guidance about its expected performance, including its susceptibility to diseases, the vine culture, and flavor characteristics of the variety produced from the parental cross. The second section presents short biographical notes of some breeders whose grapes are grown in our climate with the goal of better understanding the origin of Québec’s grape varieties. The final part presents comparative tables and summaries, as well as two climatic maps of Québec: one illustrating winter hardiness zones and the other showing summer heat summation using the growing degree-day index with a 10 °C base.

In this first inventory of the main grape varieties grown in Québec, we focused on the Vitis vinifera varieties that are present in some vineyards, as well as the semi-hardy varieties requiring winter protection and the fully cold hardy varieties. The list of grape varieties has been divided according to either the quality potential or the extent of the cultivated area of the variety in Québec (main varieties and secondary varieties). This list also includes varieties that are currently being tested on small plantings and which were judged likely to have a larger role in Québec vineyards over the next few years. This guide also aims to be a planning tool for the establishment of a vineyard by presenting a number of the cultural and organoleptic characteristics of the varieties. These characteristics are based on our observations, combined with other grape growing professionals in Québec. The information presented is empirical and reflects the performance of the vine under average growing conditions. The reader should be aware that many cultural characteristics are greatly influenced by specific geographic and climatic conditions. Thus, the choice of a vineyard location is of paramount importance. It is important to keep in mind that the observations, as well as the cultural and organoleptic characteristics of the varieties presented in this document, will be refined over time with additional observations and experience in future years of cultivation and winemaking.

Berry remarks Purplish-blue berries. White and pointy stylar scar. Thin skin. Tends to desiccate during maturation. Weight ~ 1,3 g.

Types of wines Red — Rosé — Fortified — Late harvest Organoleptic characteristics Versatile variety. When harvested at full maturity, it gives a complex and full-bodied wine with black cherry, blackberry, plum, chocolate and coffee aromas, but lacks tannin. Strawberry predominant flavor in rosés. High acidity and sugar levels. Harvest date should be based on the acidity of the berries even if the alcoholic potential is high. The acidity may decrease with the age of the plants. Tolerates the use of barrels or wood chips. Low juice yield.

General remarks Currently the best producer in quantity, in Québec. Good yield from the 3rd year. The high buds fertility gives this vine the capacity to produce a good harvest even after a spring frost. Buds of the old wood are fertile. Balance the vegetative and reproductive phase in order to avoid the development of branch with a too large diameter. A bit sensitive to early fall frosts. The propagation of Frontenac is managed by the Minnesota Nursery Research Corporation (Source: http://www.grapes.umn.edu/ Licensing/index.htm)
