Microcid SB

Microcid SB is a brewery-grade antimicrobial and antioxidant stabiliser designed for use in finished beer. Based on a synergistic blend of potassium sorbate and sulphite compounds, it protects against yeast and bacterial spoilage while preventing oxidative degradation, helping to preserve the intended flavour and stability of the final product.

Its targeted action inhibits unwanted refermentation and extends shelf life without impacting sensory quality when used at recommended dosages. Applied at the bright beer stage or prior to packaging, Microcid SB provides a reliable solution for maintaining microbiological control and product consistency in both filtered and unfiltered beers.

Microcid SB is designed to provide microbiological stability and oxidative protection in finished beer, and is suitable for use in:

• Bright beer tanks (BBT)
• Inline dosing prior to packaging
• Filtered and unfiltered beer (with controlled yeast counts)
• Prevention of refermentation in packaged beer
• Shelf-life extension through antimicrobial and antioxidant action
