Irish Ale Yeast - WLP 004

For an authentic Irish Ale experience, try WLP004 Irish Ale Yeast.

Rumoured to be sourced from the original Guinness Stout strain, applying this yeast can produce very peculiar results in a wide variety of beer styles.

With medium attenuation, high flocculation and fairly high alcohol tolerance, WLP004 is a trendy pick for fermenting Stouts, particularly Irish Dry Stouts, as well as Irish Reds, English Porters, Brown Ales, ESBs, and other styles that will benefit from the low amounts of diacetyl produced by this yeast.
