Pub A09

$11.99

Imperial Yeast's A09 Pub is a beloved and highly flocculent British ale strain that will allow you to achieve super bright ales in a short amount of time. It is one of the most flocculent brewer's strains around and it will rip through fermentation and then drop out of the beer quickly. It does produce higher levels of esters than most domestic ale strains but this allows this strain to be the perfect choice when you need a balance between malt and yeast derived esters. A09 Pub does require a sufficient diacetyl rest when being used.

If you need a substitution we recommend Imperial Yeast's A01 House, Wyeast London ESB Ale 1968, White Labs English Ale WLP002, or Omega British Ale VIII OYL016

It is well suited for a variety of beers.
