A10

Brewers love this yeast strain for dark beers. Its high alcohol tolerance makes it a go-to for big beers.

A beautiful strain for stout, porter, brown, and amber ales. Darkness produces a unique character that matches up perfectly with roasted and caramel malts. This strain is alcohol tolerant, so don’t hesitate to throw high gravity worts its way.

Beer Styles

Stout: Irish Dry
Stout: Irish Dry

A black beer with a pronounced roasted flavor, often similar to coffee. The balance can range from fairly even to quite bitter, with the more balanced versions having a little malty sweetness and the bitter versions being quite dry. Draught versions typically are creamy from a nitro pour, but bottled versions will not have this dispense-derived character. The roasted flavor can be dry and coffee-like to somewhat chocolaty.

American Stout
American Stout

A fairly strong, highly roasted, bitter, hoppy dark stout. Has the body and dark flavors typical of stouts with a more aggressive American hop character and bitterness.

American Barley Wine
American Barley Wine

A well-hopped American interpretation of the richest and strongest of the English ales. The hop character should be evident throughout, but does not have to be unbalanced. The alcohol strength and hop bitterness often combine to leave a very long finish.
