Lallemand Go-Ferm Sterol Flash – Yeast Rehydration Nutrient
Lallemand Go-Ferm Sterol Flash 100g is a natural yeast rehydration nutrient and yeast protector designed to improve yeast viability, vitality and fermentation performance.
Used during the rehydration of active dry wine yeast, Go-Ferm Sterol Flash helps strengthen yeast cell membranes before fermentation, giving yeast greater resistance to fermentation stress and helping promote a healthy, reliable fermentation.
The Sterol Flash formulation is designed for rapid dispersion and improved wettability, allowing efficient sterol integration during yeast rehydration.
Ideal for winemaking, mead, cider and other suitable fermentations using active dry wine yeast.

What is Go-Ferm Sterol Flash?
Go-Ferm Sterol Flash is a specialised yeast protector used during the rehydration stage before yeast is pitched into your must or juice.
Rather than simply adding nutrients to the fermentation, Go-Ferm Sterol Flash is used directly in the yeast rehydration water.
This allows the yeast to take up important compounds during rehydration, helping strengthen cell membranes and prepare the yeast for the stresses it will encounter during fermentation.
Why Use Go-Ferm When Rehydrating Yeast?
The rehydration stage is an important part of preparing active dry yeast for fermentation.
Go-Ferm Sterol Flash is designed to support yeast during this stage, helping improve yeast viability and vitality before pitching.
A stronger yeast population can be particularly useful when fermentation conditions are challenging, including musts with high sugar concentrations, increasing alcohol levels, low temperatures or other fermentation stresses.
Lallemand's Go-Ferm range is specifically designed for use during active dry yeast rehydration rather than as a conventional fermentation nutrient.
Fast & Easy Dispersion
Go-Ferm Sterol Flash features a larger particle size designed to provide:
- Improved wettability
- Faster dispersion in water
- Reduced dusting
- Efficient sterol integration during yeast rehydration
This makes preparing your yeast rehydration solution quick and straightforward.
Ideal for Wine, Mead & Cider
Go-Ferm Sterol Flash can be particularly useful when preparing active dry wine yeast for:
- Red wine
- White wine
- Rosé
- Mead
- Cider
- Fruit wine
- High-gravity fermentations
- Other suitable wine-yeast fermentations
The aim is to give the yeast the best possible start before it enters the must.
How to Use Go-Ferm Sterol Flash
For a typical 23 litre home fermentation:
- Measure approximately 10g Go-Ferm Sterol Flash.
- Mix into approximately 100g of 15–20°C water.
- Mix thoroughly to disperse the Go-Ferm.
- Add your dry yeast to the rehydration mixture.
- Allow the yeast to rehydrate for approximately 15 minutes.
- Pitch the rehydrated yeast into your must.
Your current product instructions specify 10g Go-Ferm Sterol Flash per 100g water for a 23L batch.
Recommended Dosage
Recommended dosage:
30g/hL based on final fermentation volume
Equivalent to:
30g per 100 litres
For a standard homebrew-sized fermentation, follow the yeast manufacturer's instructions and adjust the quantity appropriately for your batch size.
Go-Ferm vs Fermentation Nutrient
Go-Ferm is different from a conventional yeast nutrient added directly to the fermenter.
Go-Ferm is primarily a yeast rehydration nutrient/protector and is added to the rehydration water before the dry yeast is pitched.
Fermentation nutrients such as the Fermaid range are instead designed to provide nutrition during fermentation.
Lallemand's protocols commonly use Go-Ferm during rehydration followed by an appropriate fermentation nutrient where required.

Frequently Asked Questions
What is Go-Ferm Sterol Flash?
Go-Ferm Sterol Flash is a yeast rehydration nutrient and protector from Lallemand. It is designed to support active dry yeast during rehydration before the yeast is pitched into the fermentation.
What does Go-Ferm do?
Go-Ferm helps support yeast viability, vitality and membrane strength during rehydration, preparing the yeast for the stresses encountered during fermentation.
When should I add Go-Ferm?
Go-Ferm should be added to the yeast rehydration water before adding the active dry yeast. It is not intended to simply be tipped into the fermenter like a conventional yeast nutrient.
Can I use Go-Ferm for mead?
Yes. Go-Ferm is commonly useful when rehydrating suitable active dry wine yeast for mead fermentation, particularly where healthy yeast preparation is important.
Can I use Go-Ferm for cider?
Yes. Go-Ferm can be used when rehydrating suitable active dry wine yeast for cider and fruit fermentations.
How much Go-Ferm should I use?
The recommended dosage for Go-Ferm Sterol Flash is approximately 30g per 100 litres of final fermentation volume. Your 100g pack therefore provides enough for multiple home-sized fermentations.
How much Go-Ferm should I use for a 23L batch?
Your current product instructions recommend approximately 10g Go-Ferm Sterol Flash mixed into 100g of 15–20°C water for a typical 23L batch before adding the dry yeast.
Is Go-Ferm the same as yeast nutrient?
Go-Ferm is a specialised yeast rehydration nutrient/protector. It is used during yeast rehydration, whereas fermentation nutrients are generally added to the must during fermentation.
Do I still need yeast nutrient if I use Go-Ferm?
Potentially, yes. Go-Ferm prepares and protects the yeast during rehydration but doesn't necessarily replace the nutrient requirements of the fermentation itself. Lallemand protocols can use Go-Ferm during rehydration together with fermentation nutrients from the Fermaid range.
