15 Dec 2014 --- We’re pleased to introduce Jester King Bière de Blanc du Bois — a barrel aged, sour beer refermented with Texas-grown Blanc du Bois grapes. Bière de Blanc du Bois is the creation of Adrienne Ballou, Head of the Barrel Program at Jester King. Adrienne came to us about two years ago, having previously studied viticulture at U.C. Davis and worked in the wine industry in France.
