White Labs 004 Irish Ale Yeast


This yeast is from one of the oldest stout-producing breweries in the world. It’s great for many beer styles but really shines in malty British styles such as stouts, porters and brown ales. Medium attenuation helps with a dry finish that promotes roasty notes. Esters help round out the overall flavor making a soft drinkable stout.

Attenuation: 69% – 74%
Flocculation: Medium to High
Alcohol Tolerance: Medium – High (8 – 12%)
Optimum Fermentation Temperature: 65°F – 68°F
Wyeast Equivalent: 1084 Irish Ale
Imperial Organic Equivalent: A10 Darkness
Dry Equivalents: Safale S-04 (Not Perfect)
