We were asked by yeast producer Lallemand to trial an unreleased experimental yeast strain—internally code-named EXP-666—so we gave in to temptation and brewed a Belgian Golden Strong, a classic Belgian style traditionally given "devilish" names due to its deceptively dry, highly drinkable nature despite its strength (Duvel being the most famous example). Fermented with this thiol-expressive yeast, Levure du Démon develops a light white-grape aroma that descends into bright orange rind & marmalade created entirely through fermentation—no fruit added—layered over a crisp, effervescent, deceptively dangerous golden ale.
