# The Best Vacuum Seal Bags for Fermentation Source: https://fermentnest.com/best/best-vacuum-seal-fermentation-bags Updated: 2026-10-06 Publisher: Ferment Nest. Our score is an editorial rating out of 10 (fit 35%, features 25%, build 20%, value 20%), not a customer rating. Method: https://fermentnest.com/how-we-research#our-score Fermenting in vacuum bags is a technique borrowed from restaurant kitchens, and it solves the oxygen problem more completely than any jar. With the air removed there is no headspace, no film of kahm yeast, and no need for weights, since nothing can float. It suits quick vegetable ferments, fruit ferments, and hot sauce mashes especially well. The catch is that bags must be thick enough to hold a seal, and CO2 buildup means you either burp the bag or reseal it partway through. We weighed bag thickness, seal reliability with wet and briny contents, whether the bags are textured for standard suction sealers or smooth for chamber sealers, and cost per use, since bags are semi-disposable. Textured bags plus a basic suction sealer suit most home fermenters getting started. Chamber sealer bags suit high-volume users because they handle liquids without fuss. Reusable silicone bags trade some seal strength for sustainability and work for short ferments. ## Picks ### 1.
