Active dry yeast for tequila and mezcal production

Tequila classic yeast strain used for several years by tequila industry. It was selected due to its good performance in juice-producing agave tequila and mezcal. It ferments well agave juice musts supplemented with sugars that do not come only from agave, for example cane molasses or sucrose.

Ingredients: Yeast (Saccharomyces cerevisiae), emulsifier: monostearate sorbitan (E/INS491)


30-40°C (86-104°F) (optimal 32°C (90°F))

Direct pitching (no propagation):

A minimum of 25-50g per hectoliter to achieve an initial viable cell concentration approximately 18-36 billion viable cells per gallon (5-10 million per milliliter) in the fermentation vessel.

Indirect pitching (short propagation):

In state-of-art facilities, exerting strict control over contamination issues, dry yeast can be propagated during a short period (8 hours). The required quantity of yeast is 0.5g per hectoliter should be pitched in a propagation volume equivalent to a tenth or twentieth of the fermentation volume. This process would give around 10 million of initial viable cells per milliliter in fermentation if the whole propagation is transferred.

Rehydration instruction

The yeast should be rehydrated in 5-10 times its weight of sterile water, prior to using in fermentation. This should be done at 35°C (95°F) ± 5°C (9°F) for 15-30 minutes to ensure “conditioning” and a perfect homogenization.

During transport: The product can be transported and stored at room temperature for periods of time not exceeding 3 months, without affecting its performance.
