Beer Brewing Classes



WLP004 Irish Ale Yeast: 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. Gives a nice dry finish that promotes roasty notes. Esters also help to round out the overall flavor making a soft drinkable stout.

Recommended For: Ales

Attenuation: 69 - 74%

Flocculation: Medium to High

Optimum Fermentation Temperature: 65 - 68F

Alcohol Tolerance: Medium to High (8 - 12%)

Concerned about shipping? Don`t be! We ship all of our liquid yeast with ice packs.

Each vial or pouch of White Labs liquid yeast is designed to be used directly in 5 gallons of wort, hence the term `pitchable yeast.` Each vial is equivalent in cell count to a pint starter or 75-150 billion cells. One vial will usually start fermentation in a 5 gallon batch in 5-15 hours at 70F. If a faster start is desired or if initial gravity is over 1.070 we recommend a 1-2 pint starter be made or add a second vial or pouch of yeast.
