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.

Description: On the one hand, WLP004 Irish Ale Yeast tends to finish quite dry, with a nice crisp aftertaste. Yet, on the other hand, the mild fruity ethers produced by this strain can add an interesting nuance to anything from a Stout to a Pale Ale.

Thanks to the fairly high flocculation the resulting beer will be clear and visually pleasant, with a compact sediment formed after the fermentation is carried out. Definitely, a yeast strain that is fun to experiment with in various styles besides using it for the obvious choices.
