One of our most popular strains right now:

A-72 American Microbrewery Ale

Sourced from a famous brewery in San Fransisco. This versatile ale yeast produces a soft, clean, slightly nutty profile. It finishes with a slight tartness and is fruitier and more flocculant than A-56 Chico Ale. An excellent choice for American pale ale and hazy IPA.

This strain is part of our Express Yeast line and is available for next day shipment!
