For vinegar fermentation: Use fruit scraps and leftover wine to ferment sweet home-brewed fruit and red wine vinegar. Home-brewed vinegar is also rich in beneficial compounds, making it a natural probiotic. Some claim it’s a natural home remedy for colds and other ailments, and for shampoo and cleaning.

Home-brewed vinegar isn't as tart or bitter-tasting as store-bought vinegar, making it a best-kept secret for cooking and homemade salad dressings.

Add a Mother or another natural vinegar starter, then store the crock in a warm place between 70 and 80 degrees Fahrenheit. Fermentation takes about two months, so some people keep several crocks brewing at different intervals. Google “Home Brewing Vinegar” for more information.

The crock will produce approximately one dozen 16 oz. Bottles. The bottles are easy to fill because the crock has a high-quality, USA-made Polypropylene spigot. 

For Kombucha fermentation: Typically, store kombucha in a dark place during fermentation; however, this beautiful crock can be displayed on your kitchen counter because it isn't translucent like a glass brewing vessel.

Typical brewing time is 7-10 days in warmer weather and 7-21 days in cooler weather. Brewing time also varies with your home's temperature. You can shorten brewing time by using a brew belt, which significantly warms the vessel. Pottery absorbs heat well, so you can set it near a heat source to speed up brewing.

If you plan to bottle your Kombucha tea for secondary fermentation, the crock will produce about a dozen 16-oz bottles. The bottles are easy to fill because the crock has a USA-made plastic spigot.

How to Choose the Right Stoneware Crock

• Batch size: A ¾- or 1-gallon crock is useful for trial recipes; 2- and 3-gallon sizes provide more working volume.

• Lid and cover: A ceramic lid is useful for storage, but some active ferments require a breathable cover or a recipe-specific fermentation lid and weights.

• Fermentation type: Choose a spigot crock for kombucha or vinegar when convenient dispensing matters.

• Material: Select food-contact-safe, intact glazed stoneware; inspect for cracks and damaged glaze before each use.

• Appearance and lead time: Blue-stripe, plain white, custom colors and personalization vary by listing; handmade pottery may require additional production time.

Practical Fermentation Tips

Wash and sanitize equipment as appropriate for your recipe. For fermented vegetables, follow a tested recipe with the specified salt concentration, keep vegetables submerged beneath brine, and use suitable fermentation weights. Keep vessels in a stable, recipe-appropriate temperature range. Discard batches with signs of spoilage. For kombucha and vinegar, use a validated method and the correct breathable cover during active fermentation; the pottery lid may be intended for storage rather than sealing an active ferment. Don't assume fermented foods are shelf-stable; refrigerate or preserve them using a tested process.
