Control Unwanted Fermentation in Kegged Drinks
Impressence Ferm Stop is a powerful yeast inhibitor designed to help prevent unwanted fermentation and spoilage in sweetened kegged drinks, premixed alcoholic beverages and Impressence flavour recipes.
Rather than killing the yeast, Ferm Stop inhibits its ability to multiply and remain active. This helps protect the intended sweetness and flavour of compatible beverages after sugar and flavouring have been added.
The 50ml sachet treats approximately 19 litres when used at the recommended rate of 2.6ml per litre.

How to Use Impressence Ferm Stop
Measure the required amount according to the finished volume of your beverage.
Add Ferm Stop as directed by your Impressence recipe and mix thoroughly to ensure it is evenly distributed throughout the drink. Maintain suitable sanitation and cold-storage practices after preparation.
Always follow the instructions supplied with the applicable beverage recipe.
Does Ferm Stop Kill Yeast?
No. Ferm Stop is a yeast inhibitor rather than a yeast killer. It restricts the yeast’s ability to multiply and remain active, helping prevent unwanted fermentation in compatible beverages.
Can Ferm Stop Be Used to Stop an Active Fermentation?
Ferm Stop should not be relied upon as the primary method of stopping a vigorous active fermentation. Complete the required fermentation and stabilisation process for your beverage before adding sugar or packaging.
It is intended to inhibit unwanted yeast activity in compatible finished-drink recipes.
How Much Does One Sachet Treat?
The recommended dosage is approximately 2.6ml per litre. One 50ml sachet therefore treats approximately 19 litres of finished beverage.
For a 9.5-litre batch, use approximately 25ml.
Is Ferm Stop a Sanitiser?
No. Ferm Stop is not a cleaning or sanitising product. All kegs, fermenters, utensils and dispensing equipment must still be properly cleaned and sanitised before use.
Can I Naturally Carbonate After Adding Ferm Stop?
Ferm Stop inhibits yeast activity and may prevent reliable natural carbonation. It is primarily suited to kegged beverages that will be force carbonated with CO₂.
Do not bottle a sweetened beverage unless you are using a tested recipe and appropriate stabilisation process.
Does Ferm Stop Replace Refrigeration?
No. Ferm Stop does not replace correct sanitation, refrigeration or safe beverage-handling practices. Keep prepared drinks stored according to the recipe instructions.
