Independence A15


Imperial Yeast's A15 Independence is an American ale yeast strain. It is slightly ester forward and loves to play with hops. It will truly bring new character to your hop-driven beers. It will give some fruit character to your beer due to the higher ester content. This strain is guaranteed to take your hoppy beers to a whole new level.

If you need a substitution we recommend Imperial A07 Flagship or A01 House, Wyeast American Ale II 1272, or White Labs California V Ale WLP051,

It is a great choice for hop-driven beers, Pale Ales, IPAs, Stouts, and English Ales. It's really a great well rounded strain that works in practically any style.
