Cover your primary fermenter and keep insects, dust, and airborne spoilers out during open fermentation.
These food-grade plastic sheets are designed to cover primary fermentation buckets during open fermentation, creating an effective barrier against fruit flies, dust, and excessive oxygen exposure. Large enough to drape over a standard 27L primary fermenter and secure with a rubber band or lid rim. Sold in a 10-pack for multiple batches or ready replacement.

Winemaker's Tip: Don't seal the sheet airtight during active fermentation — CO₂ needs to escape. A loosely draped cover is all you need.
