FermentMate™ Tamper-Evident Relief Caps – Pressure-Regulating Lids for Beer, Kombucha, Sparkling Wine, Soda & More (32-Pack Yellow Valve Replacement Relief Caps)
Product Information
About
【Includes Yellow Valve Relief Caps】– Each set comes with 32 Yellow Valve Relief Caps featuring a built-in silicone valve to maintain optimal carbonation by venting excess pressure during fermentation. Relief Cap is designed specifically to regulate gas production from aggressive active fermentations. FermentMate is designed to prevent excessive bottle pressure caused by over priming or when a living fermentation is desired. It cannot address under priming & will not revive a stale or dead fermentation.
【Tamper-Evident Ring】– Relief Caps include a breakaway ring that snaps upon first opening, offering a clear visual indicator of whether a bottle has been previously opened—just like store-bought beverages.
【Perfect for Fermented Beverages】– Designed for active fermentation of naturally carbonated drinks like kombucha, home-brewed beer, sparkling wine, mead, and more.
【Compact & Practical Design】– Relief's Fermentmate System is easy to handle, and clean—great for single servings, test batches, or small-batch brewers.
【Customizable Pressure Options】– Expand your setup with replacement Relief Caps in multiple pressure ratings and colors (sold separately): 🔴 Red (Very Low – 8.7 psi) 🟡 Yellow (Low – 12.3 psi) 🟢 Green (Normal – 16.4 psi) 🔵 Blue (High – 20.5 psi) 🟣 Purple (Very High – 24.9 psi)
