Ice Options *

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.

A complex alternative to the standard German wheat strain profile. This strain produces apple, pear, and plum esters in addition to the dominant banana character. The esters are complemented nicely by clove and subtle vanilla phenolics. The balance can be manipulated towards ester production through increasing fermentation temperature, increasing the wort density, and decreasing the pitch rate. Over pitching can result in a near complete loss of banana character. Decreasing the ester level will allow a higher clove character to be perceived. Sulfur is commonly produced, but will dissipate with conditioning. This strain is very powdery and will remain in suspension for an extended amount of time following attenuation. This is true top cropping yeast and requires fermentor headspace of 33%.

  • Flocculation: low
  • Apparent Attenuation: 70-76%
  • Temperature Range: 64-75°F (18-24°C)
  • Alcohol Tolerance: 10% ABV

Activator packages are designed for direct inoculation of 5 gallons of standard wort. Activator packages contain at least 100 billion live yeast cells in a liquid slurry. This yeast slurry is packaged in an optimum condition for storage, while maintaining the ability for rapid and complete fermentation.
