Imperial Yeast: A09 Pub

Highly flocculent English ale yeast strain.

Brewers swear by this strain to achieve super bright ales in a short amount of time. One of the most flocculent brewer’s strains around, Pub will rip through fermentation and then drop out of the beer quickly. Pub produces higher levels of esters than most domestic ale strains. Be sure to give beers made with Pub a sufficient diacetyl rest.
