Other than a mixture of wine, water and a mother, the only other supplies you’ll need are a 1-2 gallon vessel to ferment the vinegar and some cheesecloth. A ceramic crock works well because it keeps out damaging light, but a jar wrapped with cloth or paper to keep out the light could work, too. Covering the top of the vessel with cheesecloth keeps insects out, but lets air get in to feed the bacteria. Tucked away in a warm, dark place, the magical transformation into tasty red wine vinegar will begin. Months later, you’ll be rewarded and we think you’ll agree, it’s worth the wait.
