There is an article in the Winter 2004 edition of the "American Wine Society Journal" written by Paul V. DiGrazia, M.D. that compares the polyphenol antioxidants in red and white wines to his "Wild Blue fortified blueberry wine and his DiGrazia Vineyards Wind Ridge Seyval Blanc blend.
The wines were analyzed by Vinquiry which is a BATF-certified laboratory in Windsor, California
In summary:
Sample type Polyphenols (mg/l)
DiGrazia Vineyards Wild Blue fortified blueberry wine 6236 Cabernet Sauvignon (3 brands sampled) 3400-3760 Merlot (3brands sampled) 2777-3260
DiGrazia Vineyards Wind Ridge Seyval Blanc blend 715 Chardonnay (11 brands sampled) 270-520 Pinot Grigio(2 brands sampled) 340-350 Chablis (3 brands sampled) 320-350
Dr. DiGrazia used "ethanol extraction" in which he immersed seeds and skins of the fruit in a solution of ethanol. No details were supplied.
This got me thinking of experimenting by adding some blueberries to a small trial batch of grape wine. I have heard that in the past, some have used elderberries with grapes to give more color and body. Maybe we can concoct a "Super" healthy wine - ha ha. I might even get brave and go for the gusto and add elderberries, blueberries, pomegranate and cranberries to the grapes. I should live forever - ha.
Has anyone experimented by adding any of the fruits to their grape wines and what was the resulting taste?
