From one of the oldest stout producing breweries in the world. It produces a slight hint of diacetyl, balanced by a light fruitiness and slight dry crispness. Great for Irish Ales, Stouts, Porters, Browns, Reds and a very interesting Pale Ale. To ferment this yeast properly pitch at 63-65F and let it rise to 65-68F. Ferment for 10-14 days in the primary. This strain can be used in all ales because of its clean crisp character it produces. Irish ale can also be used to help finish a beer's stuck fermentation.

Attenuation: 69-74%.
Flocculation: Medium to High.
Optimum Fermentation Temp: 65-68.
Wyeast Equivalent: 1084 Irish

For best results we always recommend ordering an ice pack with your liquid yeast.

Quick starter
Used a yeast starter, and had activity within 8 hours. Finished a bit high at 1.014. Created a nice malty Irish red ale.

So far the yeast had no flocculation, which I know it states low Flocculation but this had zero. I was nervous because this was for a 1BBL batch. The yeast showed up 4 days late after ordering and paying for two day delivery. Cold packs were melted and warm. But.... the Fermenter is moving along in our 1 BBL glycol conical

Awesome Strain
Incredible attenuator - prepared a 1.5L starter for a six-gallon batch of an English-inspired milk stout (1.057 OG), and the yeast took off in the first 8-12 hours. Temperature rose from 64 to 72 degrees F within first 36-48 hours, and the activity in the airlock is unlike anything I have seen to date. Looking forward to the results!

Awesome Irish Ales
I used this yeast a few times to brew porter, stouts, and red ales. Awesome yeast, easy to pitch, ferments well, and great results.
