Demi-Tone (blueberries) follows in our lineup of refermentations with spent fruit, which includes La Vie en Rose (raspberries), Detritivore (cherries), and Grim Harvest (blackberries). The result of refermenting on spent fruit is a more subtle fruit character and arguably more complexity in terms of the fermentation profile. Demi-Tone is a really great expression of one of our core philosophies — allowing native yeast and bacteria to create interesting flavors and aromas through the fermentation of grains and fruit.
