Wine and Cheese Lovers Rejoice

If you’re a fan of wine and cheese, today is your day to celebrate. A new study put out by a team of scientists out of Iowa State University noted that these two items can improve both cognitive function as well as combat against age-related cognitive degeneration such as Alzheimer’s disease. When the team evaluated a study of nearly 1,800 aging adults and their consumption of a broad range of food and drinks, what they uncovered was that cheese was hands down the best food to enjoy in order to protect against cognitive problems later in life. They also found that moderate daily consumption of alcohol (red wine in particular) improved cognitive function. If this topic peaks your interest, you can learn more at:

What Makes Vitis vinifera So Special?

Geneticists at UC-Davis have successfully unlocked one of the deeper mysteries surrounding what makes domesticated Vitis vinifera so special in the grape world — the trait that causes vinifera grapes to grow in large and plentiful bunches. Most grape species in the world have male and female plants and their grape bunches can be sparse and irregular. The mystery begins when we learn that male grape vines do have female parts and vice versa. But the female’s pollen will be sterile while male plants have pistils that are reduced and incapable of being fertilized . . . in other words, also sterile. But domesticated wine grapes are hermaphroditic, meaning every vine contains fully functional male and female flower parts. This allows pollination to occur with a very high success rate.

What the scientists found was that it actually required two distinct mutations, in two separate genes, for this transformation to occur. In other words, two mutant wild grapes species must have mated: One a male with unsuppressed female fertilization capacity crossed with a female with unsuppressed male fertilization capacity . . . a recombination event. This “freak” mating event that occurred thousands of years ago gave rise to our fruitful, domesticated grape vine. Why this happened remains a mystery, but how it happened, genetically speaking, can now be explained. https://www.sciencedaily.com/releases/2020/06/200618150313.htm

Cider Vocabulary Standardization

The USDA (United States Department of Agriculture) announced that they have approved a grant of $500,000 to Virginia Tech and Cornell scientists to standardize the vocabulary used for cider. Currently, definitions for criteria such as sweetness levels are set by the individual cider producer. This can mean that one cidery’s “dry” cider may actually contain quite a bit more sugar than another cidery’s. Their goal is not to dictate how different cidermakers make their beverages, but rather to have consumer’s expectations be met. This is similar in a sense to the way many in the wine industry must comply with rules when describing a newly-released wine, such as varietals versus blends. https://vtnews.vt.edu/articles/2020/09/fst-usda-cider.html

Oak Adds Bitterness?

We hope every winemaker who reads this magazine knows some of the positive phenolic compounds that oak products can add to their wine. Tannins provide an astringency that can make wine have a drying effect on your mouth. Then there are the flavonoids that, depending on the toast level and origin of the wood, provide coconut, vanilla, and smoky-spice flavors to wines aged on oak. But a newly published study by a group out of the Université de Bordeaux in France has found that there may be more than just that. What the study focused on was the contribution by a class of phenolics known as coumarins may also be adding bitterness to wines that are oaked. Coumarins are bitter compounds known to deter herbivory, protecting the oak trees from being eaten. Through experimentation, they found that oaked wines are much higher in coumarin levels than wines not aged in oak, and the longer the wine was aged in oak, the higher the coumarin levels. https://pubs.acs.org/doi/10.1021/acs.jafc.0c02619

Brewer’s Best® Kombucha Kits

A new series of kombucha recipe kits by Brewer’s Best® allows home winemakers to craft their own flavored kombucha at home. Each kit comes with the ingredients to craft one gallon (3.8 L) of fresh kombucha and is available in four flavors: Blackberry, hemp, passion fruit, and raspberry. Note that these kits do not include a SCOBY for fermentation, which needs to be purchased separately from a supplier. SCOBYs are not included since they can be reused time and again and don’t need to be started fresh each time. First time making kombucha?
