WLP603 Torulaspora Delbrueckii Yeast: A wild yeast isolated from fruit trees in Denmark. One of three strains that make up WLP611. Has been used for ciders, wine, or beer. Produces a lot of esters and contributes some phenolics as well. Traditionally a longer fermentation and slower attenuator. This strain should be used in a mixed fermentation.

This is a Vault Yeast Strain and is only released July/August/September.

Recommended for: Ciders, Wines, and Ales.

Attenuation: 30 - 50%

Alcohol Tolerance: Medium (5 - 10%)

Flocculation: Low to Medium

Optimum Fermentation Temperature: 50 - 86%F

Concerned about shipping? Don`t be! We ship all of our liquid yeast with ice packs.

Each vial or pouch of White Labs liquid yeast is designed to be used directly in 5 gallons of wort, 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 a 5 gallon batch in 5-15 hours at 70F. If a faster start is desired or if initial gravity is over 1.070 we recommend a 1-2 pint starter be made or add a second vial or pouch of yeast.
