This robust English yeast can ferment up to 25% ABV, making it perfect for strong beers like Barleywines. While alcohol may typically halt around 12–16%, YF-666 can push higher under special conditions. Its fermentation produces a pleasant, balanced English ale profile with a smooth finish, even at high strength. The yeast emphasizes malt richness while allowing subtle fruity esters to shine. YF-666 is ideal for brewers crafting powerful yet drinkable ales with a classic English character.
