Go-Ferm Sterol Flash™ – Advanced Yeast Rehydration Nutrient for Wine, Cider, Mead and Fruit Wine

Go-Ferm Sterol Flash™ from Lallemand is the latest generation of yeast rehydration nutrients developed for modern wine, cider, mead and fruit wine production. The product is based on natural yeast autolysates with a high content of bioavailable sterols that strengthen the yeast cell membranes during rehydration.

The patented microagglomerated technology enables faster and more efficient sterol uptake compared with traditional yeast rehydration nutrients. The result is improved yeast health, greater vitality and a more reliable fermentation – even under demanding conditions.

Why choose Go-Ferm Sterol Flash™?

Rapid dry yeast rehydration in approximately 15 minutes
Can be used in water above 15 °C
Improves yeast vitality and resilience
Enhances sterol uptake during rehydration
Reduces the risk of stressed or weakened yeast
Contributes to a more stable and reliable fermentation
Suitable for wine, cider, mead and fruit wine

Benefits of Go-Ferm Sterol Flash™ during fermentation

A healthy yeast start is essential for aroma development, complete fermentation and overall product quality. Go-Ferm Sterol Flash™ helps the yeast build stronger cell membranes, resulting in better tolerance to alcohol, sugar and other fermentation-related stresses.

The product is particularly beneficial for cider, mead and wines with a high sugar content, for low-temperature fermentations or for fermentations where maximum yeast health and aromatic quality are required.

Improved aroma and greater fermentation reliability

Lallemand trials show that Go-Ferm Sterol Flash™ can improve the yeast’s ability to absorb aroma precursors from the must. This can contribute to more complex and fruit-forward aromas in the finished product while reducing the risk of slow or problematic fermentation.

For producers of wine, cider and mead seeking maximum control over fermentation, Go-Ferm Sterol Flash™ is among the most advanced yeast rehydration nutrients available.

How to use Go-Ferm Sterol Flash™

Go-Ferm Sterol Flash™ is used when rehydrating dry yeast before addition to the must. The product is designed for rapid dissolution and efficient sterol uptake, making it possible to complete the rehydration process faster than with traditional yeast rehydration nutrients.

Always follow Lallemand’s current dosage instructions for the selected yeast strain.

Temperature is essential for a healthy yeast start

Lalvin dry yeast consists of living yeast cells that must be handled correctly during rehydration and addition to the must. An excessive temperature difference between the yeast solution and the must can stress the yeast and reduce both its vitality and fermentation reliability.

Whether you use GoFerm, Go-Ferm Protect Evolution or Go-Ferm Sterol Flash, always follow the instructions for the selected product. The individual products are used at different temperatures and with different rehydration methods.

When the yeast is ready for addition, the temperature difference between the yeast solution and the must should not exceed 10 °C. If the difference is greater, gradually acclimatise the yeast by slowly adding small quantities of must before the final addition.

When should Go-Ferm Sterol Flash be used?

The product can be used for all types of must and juice, but is particularly suitable for:

Producing highly aromatic wines, meads and ciders
Very clear must with a low nutrient content
Barrel fermentation
Must with a high sugar content
