A fast-fermenting English ale yeast that drops clear and brings a touch of fruit.
Better still, ferments fast and clears up well. And there's more. Suits English bitters and ambers, and works well for stouts too. High flocculation gives a cleaner, clearer beer.
One sachet pitches a standard batch, so there's no guesswork on quantity.
Ferment temperature and attenuation are in the tabs below. We stock a range of yeast for whatever you're brewing next.
