Activate® Yeast for Rum

Activate® Yeast for Rum is the world’s most efficient yeast for the production of high-quality and smooth tasting rum. Our yeast can ferment near 100% of all sugars to produce a high-quality rum, while naturally generating the glucoamylase enzyme required to convert some of the unfermentable sugars into fermentable sugars for fermentation.

Customer Performance Benefits 

Activate® Yeast for Rum produces alcohol in low pH and high alcohol conditions, in which microbes cannot survive 

  • Reduce Operational Costs: Shorter fermentation times lead to lower operational expenses
  • Improve Asset Utilization: Notable process efficiencies resulting in fixed (equipment) and variable (energy) costs savings
  • Increase Profitability: Produce more rum with higher yields and expanded production capabilities via shorter cycle times 

Production Advantages 

1) High Quality, Smooth Tasting Rum 

Our yeast achieves industry-leading yields, while producing a premium vodka or gin 

2) Superior Sugar Conversion Capabilities 

Capable of expressing the glucoamylase enzyme required to convert near 100% of sugars into fermentable sugars. 

3) Efficient Rum Fermentation Process 

Conversion of nearly all sugars into gin or vodka within 24-48 hours

Product Storage Recommendations

Activate® Yeast for Rum is provided as a stabilized liquid cream yeast (20-22% solids). The product is stable for up to 3 months from date of manufacture when stored at refrigeration temperatures (4°C, 40°F).

Regulatory Compliance

Activate® yeast was certified by an independent scientific expert panel in accordance with U.S. Food and Drug Administration (FDA) guidelines to be GRAS (Generally Regarded as Safe), as a processing aid in the production of alcohol for human consumption.

Protocol for Use

The recommended dosage of Activate® Yeast for Rum is 1L (or ~0.25 gallons) of liquid cream yeast per a 500-gallon vodka or gin fermentation. Please consult your technical support representative for details related to your process.

The ideal fermentation temperature range for Activate® Yeast for Neutral Grain Spirits is 30-32°C (86-90°F) and the ideal pH range is 4.0 to 5.5. The yeast should be supplied sufficient nitrogen to provide a robust and complete fermentation. It is advisable to supply nitrogen, at levels of 500-1500 ppm urea or 200-700 ppm of ammonia.
