Traditionally, natural cork has been the preferred seal in use since the early 1400s. Cork comes from the bark of the cork oak tree, which is indigenous to southwestern Europe and northwestern Africa. Seventy percent of the world’s cork comes from forests in Portugal, Spain and France. Cork trees cannot be harvested until they are 25 years old, and the trees produce good cork for about 300 years. Their bark is stripped every nine years. High-quality cork is very expensive, so it is typically reserved for higher-valued wines. Though considered to be impermeable, natural cork does pass oxygen through its fiber, but it does so at such a slow rate that it is considered to be ideal for the proper aging of fine wine. Therefore, the primary benefits of natural cork are: its ability to properly age wine through slow oxygen transmission, and it is a natural, renewable resource.

Screw tops have been in use since 1964, and were developed primarily due to the rising cost of natural cork. These seals became even more popular in the 1980s, during a period when poor-quality cork was being produced and giving rise to incidents of TCA (also known as “cork taint,” the chemical contaminent 2,4,6-Trichloroanisole that can destroy wine).

Today, screw tops are very popular because of their low cost (oftentimes a third of the price of natural cork for a comparable seal) and the protection they offer against cork taint. Though advances in seal permeability have improved the screw top’s ability to age wine in a way comparable to cork, the seal still suffers from its image as a “cheap” seal. This is changing, however, as many producers are sealing high-end wines using screw tops, and their image will likely continue to change as customers become more familiar with them.

So which seal is better? The correct answer is that they both are good seals, with unique pros and cons. Corks are more traditional, preferred for pricier wines and are widely considered to be an ideal seal for aging fine wines. Screw tops have improved significantly, are much more cost effective than natural cork and do not introduce TCA into the wine. We’ll let you be the judge.

Cheers!
