Tartan Ale Yeast | Imperial Yeast A31

Brew Malt-Forward Beers with a Clean Fermentation Profile

Imperial Yeast A31 Tartan is a traditional Scottish ale strain, perfect for crafting malt-forward styles like Scottish ales, Wee Heavies, and red ales. Known for its ability to enhance malt character, this yeast creates rich and flavorful beers with a clean fermentation profile. While ideal for traditional styles, it also works well in hop-forward beers like IPAs. Fermenting at the higher end of its temperature range can increase ester production, adding subtle fruity notes to your beer.

Our Commitment to Yeast Health

At SoCal Brewing Supply, we take yeast storage and viability very seriously. We ensure yeast is always stored under optimal conditions, with 24-hour monitoring of refrigerator temperatures to prevent spikes that could negatively impact yeast health.

For liquid yeast orders, we recommend shipping with an ice pack and insulated envelope to ensure your yeast arrives in top condition. It’s normal for ice packs to melt during transit; their purpose is to protect the yeast from extreme temperatures caused by external weather conditions.
