Darkness A10

$11.99

Imperial Yeast's A10 Darkness is a perfect yeast strain for dark beers due to its high alcohol tolerance. This strain produces a unique character that matches perfectly with the character of roasted, toasted, and caramel/crystal malts. It is a fantastic choice for high gravity worts due to its alcohol tolerance, so don't hesitate to throw it in.

If you need a substitution we recommend Imperial Yeast A31 Tartan, A07 Flagship, or A15 Independence, Wyeast Irish Ale 1084, or White Labs Irish Ale WLP004, or Omega Irish Ale OYL005

It is a great choice for big beers like Stouts, Porters, Brown Ales and Amber Ales.
