Fat’s Effect On Your Red Wine

We would assume that everyone that is reading this knows how your selection of wine can have an effect on your dining experience. Some wines may enhance the food while others may detract. But most of us also know that the inverse is true . . . food selection can have an effect on the wine. For example, eating something sugary may really bring out the acidity and bitterness of a wine. But a new study put out by the Université Bordeaux located in Pessac, France found that fats in food will interact with the tannins from red wines, changing the character.

This study basically reconfirms a key age-old belief when it comes to wine-food pairings a big tannic wine like a Bordeaux pairs nicely with fatty foods like a seared filet mignon. It turns out that the fat (lipids) in the steak will actually interact with the tannins of the red wine, rendering them almost imperceptible to our senses. The scientists used several oils, like olive and grapeseed, and had testers consume a spoonful prior to tasting one of the more well-known tannins, catechin, to see how their perceptions changed. What tasters found was that instead of getting astringency from the tannin, they now found a more fruity taste notably with olive oil. The tannins can no longer bind to our saliva glands, where the astringent sensation in our mouth is derived. https://arstechnica.com/science/2021/03/study-examines-molecular-basis-for-why-wine-goes-so-well-with-fatty-foods/

Terroir Finally Proven?

At last, scientists may have found chemical proof that the concept of a vineyard’s terroir does actually exist . . . well at least in the Mendoza region of Argentina. Terroir is a concept that says soil and climate will provide particular nuances to wines made from grapes from a specific vineyard year after year. But solid proof of the concept has long eluded researchers. A group from the Catena Institute of Wine, a collaboration between UC-Davis and the Argentinian Universidad Nacional de Cuyo, looked at 23 different vineyards in 12 different geographic indications in Mendoza to see if the chemical composition of the vintages changed year-over-year. By looking at vintages from 2016, 2017, and 2018, they were able to successfully identify a wine’s origins based on its phenolic composition for 11 of the vineyards 100% of the time. The other 12 vineyards, the scientists were able to identify the origins 83% of the time based on the phenolic indicators. Learn more about the study at: https://doi.org/10.1038/s41598-021-82306-0

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:
