Covertec Breathable & Non-Breathable Ferment Covers

Professional quality ferment covers designed to protect open fermentation vessels while accommodating different process needs.

Made from food-grade materials, these covers help keep insects, dust, vermin and other contaminants out of your open fermenters, bins and vats. Each cover has an elastic drawstring and reinforced hem for secure fitting and easy handling. 

Choose breathable options for fermentation processes that require gas exchange and CO2 release, or non-breathable styles when tighter environmental control around the ferment is needed. Available in round, square and rectangular profiles to match a wide range of tanks and vessels.

Breathable covers are made from non-woven polypropylene for effective airflow while keeping pests and debris out. Non-breathable covers are made from durable polyester to provide a more enclosed environment when required. All covers feature a satin hem with elastic drawstring for a snug, adjustable fit and compatibility with optional hoop or conduit frames.

Whether you’re fermenting wine, beer, kombucha, cider or other beverages, these ferment covers are a practical solution for commercial and craft operations.
