White Labs Liquid

Each vial of White Labs liquid yeast is designed to be used directly in 5 gallons, hence the term "pitchable yeast." Each vial is equivalent in cell count to a pint starter, or 75-150 billion cells. One vial will usually start fermentation in 5 gallons in 5-15 hours at 70°F. If a faster start is desired, or if initial gravity is over 1.070, we recommend a 1-2 pint starter be made.

Liquid yeast is shipped with an ice pack during the warmer months. Nevertheless, summer temperatures do present challenges in the hotter regions of the country and we recommend that liquid yeast is shipped UPS 2nd Day Air to guarantee viability.  Simply note UP2 yeast only in the comment section.
