Home Brewing Products

Wyeast Laboratories has been producing pure liquid yeast cultures for commercial breweries and home brewers for over 20 years. Over time, we have added many new specialty strains to our line-up, as well as refining our packaging. We now offer a packaging size and style to meet all your brewing needs.

Our Smack-pack System allows yeast metabolism to begin, providing proof of healthy yeast ready for brewing. It is not necessary for the packages to fully swell before use.
