We know the benefits of eating fermented foods (https://draxe.com/fermented-foods/) but how do you make a small batch? We like sauerkraut and kimchi but don’t need to make a lot so this fermenting kit is just the ticket! It has the 4 air locks, 4 sturdy white screw-on lids for wide mouth mason jars, 4 silicone gaskets, 4 grommets, 1 (2-sided) instruction/recipe sheet. All components are BPA-Free. Does not include the glass quarts.
