All liquid yeast being shipped includes a complementary ice pack per shipping order when temperatures are above 50F. Although we cannot guarantee that the ice packs will stay cold during shipping, we highly recommend the addition of an insulated mailer. Store pickup orders do not include an ice pack, but may be purchased with yeast or kits.

*Selecting the “Ice Pack” option adds an additional ice pack to shipping orders, or a single ice pack to store pickup orders.
**Selecting the “Insulated Mailer” option will add an insulated envelope and additional ice pack to shipping or store pickup orders.

True top cropping yeast similar to Alt strains. Produces slightly more fruity/winey characteristics. Fruitiness increases with temperature. Low or no detectable diacetyl production. Also ferments well at cold 55-60°F (13-16°C) range. Used to produce quick conditioning pseudo lager beers. Poor flocculating yeast requires filtration to produce bright beers, or additional settling time.
