How much protein is in an 4 ounce glass of red wine?

Here's why:

* Wine is primarily made from fermented grapes. Grapes are mainly carbohydrates (sugars) and have very little protein.

* Fermentation process: During winemaking, the sugars in grapes are converted into alcohol and other compounds, further reducing any potential protein content.

So, while you might find trace amounts of protein in red wine, it's negligible and not a factor to consider for your dietary protein intake.
