Is it beer, or is it wine? “Aged in French oak wine barrels for twelve months with distinct characteristics of fruit and subtle oak” sounds more like a description of wine than beer. But, of course, Temptation is indeed beer. Flavors of wine and oak absorb into the brew throughout twelve months of aging. During this aging process, a secondary fermentation occurs using a yeast strain disliked by most brewers and winemakers called Brettanomyces. The “Bret” gives Temptation intriguing characteristics and a pleasant sourness. Temptation is re-fermented in the bottle to create its carbonation—a process commonly used to make fine champagne and sparkling wine. Spent yeast forms a thin layer of sediment to remain in the bottle.
