Impressence - FermStop - 50mL

FermStop – Fermentation Inhibitor & Spoilage Preventer

FermStop is an effective and reliable solution designed to halt fermentation and prevent spoilage in your brew. Rather than killing yeast outright, FermStop works as a yeast inhibitor, disrupting the yeast’s ability to multiply and remain active. This makes it ideal for stopping fermentation at a specific point or for stabilising before bottling or backsweetening.

Whether you're looking to retain residual sugar, prevent over-fermentation, or preserve flavour profiles, FermStop gives you greater control over the process and helps ensure long-term product stability.

Usage Instructions:

• 1 sachet per 9.5–10L of wash

• 2 sachets per 19–20L of wash

• Liquid dosing rate: 2.6mL per litre

Perfect for winemakers, cider brewers, and distillers who need to precisely stop or stabilise fermentation.

FermStop is a must-have tool for maintaining quality, consistency, and shelf life in your finished product.
