East Coast Yeast’s Mission is: “To provide new, fresh, liquid cultures for your special brewing projects. Specializing in artisanal yeast blends and pure yeast strains long forgotten.”

Actually… Finding East Coast Yeast

East Coast Yeast is tough to find in stock. It’s in high demand and distribution is very limited. Fermented NJ is one of a very few sources where you can actually get ECY. Stock is usually limited and can change quickly

East Coast Yeast Strain Guide!

BugFarm ECY01 – Large complex blend of cultures to emulate sour or wild beers such as lambic-style ales. Over time displays a citrus sourness and barnyard funk profile. Contains yeast (Saccharomyces, Brettanomyces) and lactic-acid producing bacteria (Lactobacillus, Pediococcus). The Brett population is > 50% of the culture. The BugFarm blend changes strains every calendar year for those who like to blend aged brews. The 2014 version contains a wild Saccharomyces yeast and four different brett isolates, L. brevis and Pediococcus.

Flemish Ale ECY02 – A unique blend of Saccharomyces, Brett, Lacto & Pedio perfect for flemish reds and sour browns. Dry, sour, leathery and notes of cherry stone. Designed for 5 gallon pitch, but may be added at any stage of fermentation.

Available Strains

Being a small yeast house affords ECY the luxury of providing homebrewers with a variety of yeast. Beyond the general availability issues that have already been mentioned ECY changes strains, this guide is a reference that lists all strains that we’ve become aware of. That to say, not all strains are produced.
