Fermentation Jar with Water Seal: The water-seal fermentation crock provides an airtight environment for fermentation, supporting sauerkraut and wine brewing while preventing unwanted smells, dust, and chemicals from leaching into the pickles. Two sizes, glass jars with lids: 2.5 L and 1.5 L glass jars with lids offer versatility for homemade pickles, kimchi, vegetables (onions, ginger, garlic, cucumber, carrots, cabbage), canned peaches, jams, jellies, tomato sauces, brewing, and preserving wine. Durable glass construction: Thick, healthy glass build designed for long-term use for kimchi, pickles, and wine brewing, or storing dry foods. Easy to use and maintain: To seal, pour water around the bowl lid to create an airtight environment and keep out outer dust. Wash with kitchen detergent and dry thoroughly, then store in a dry place. Remember to add water to the bowl lid channel every week. Practical use scenarios: - Ferment sauerkraut or kimchi at home with a reliable seal. - Create small batches of pickles or vegetable mixes (onions, garlic, cucumber, carrots, cabbage) for daily use. - Brew wine in small quantities or preserve items like jams, jellies, tomato sauces, or peaches for later.
