During the 2011 grape harvest, our youngest brother John (winemaker for Sante Arcangeli Family Wines) set aside some Chardonnay grapes and fermented them with the vineyard yeast in a bucket. He turned that fermentation into a sourdough starter. After 2 years of letting the sourdough cultures build up, he gave it to us. This is the result: a true rustic sourdough made from Chardonnay grapes. A thick crust, dense crumb and sour kick make this a one-of-a-kind old-world sourdough.
