Nutri-Lock Vacuum Sealer Bags, Commercial Grade, Works with Sous Vide, BPA Free, 100 Quart Bags 8 x 12 Inch
Nutri-Lock's commercial grade BPA free vacuum sealer bags, 100 Quart Bags at 8 x 12 Inch that work with sous vide.
Syntus 3 Rolls 8" x 20' Vacuum Sealer Bags, BPA Free for Food Storage
Syntus set of 3 vacuum sealer rolls, each 8 inches by 20 feet (60 feet in total), embossed on one side and cut to length for bag ferments of any batch size.
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.
