Ethanol Red®

The industry standard for industrial ethanol production

Ethanol Red ® is the industry standard in biofuels production. Ethanol Red ® is our rapid fermenting, temperature-tolerant strain of yeast that displays higher alcohol yields and maintains higher cell viability during Very High Gravity fermentation. Ideal for the production of industrial ethanol from starch substrates, Ethanol Red ® is designed for maximizing alcohol yields under a wide range of fermentation conditions.


Performing Very High Gravity fermentation offers many upsides from water savings, wastewater reduction, CO2 emissions reductions, as well as energy savings at distillation allowing a cost reduction per volume of ethanol produced.


Carrying out such fermentations requires, among other conditions, an optimized propagation reaching at least 300 million yeast/mL. EthanolRed®’s rapid growth rate properties make it the ideal yeast to perform Very High Gravity fermentations.

Meeting the needs of our partners with a fast acting strain

Performing Very High Gravity fermentations

Our Ethanol Red® strain tolerates high ethanol concentrations and high temperatures, even if recommended temperatures are exceeded. Such robustness allows our partners to perform stable Very High Gravity fermentations and to sustain plant performances by limiting day-to-day disruptions.

Relying on fast kinetics in fermentation processing

During propagation, our Ethanol Red® strain displays a higher growth rate and faster kinetics enabling our partners to maintain yields. These fast kinetics help limit the competition between yeast and other organisms during fermentation.

Saving energy through
higher productivity

With Ethanol Red®, we allow our partners to reach higher ethanol titers up to 19 v/v As the ethanol concentration increases, energy needs decrease reaching such titers enables a substantial reduction in a plant’s energy consumption.
