Making apple cider vinegar (small-batch home method to yield ~16 fl oz)
- 2
- 3
Combine liquids and sugar
Pour 8 cups (about 1.9 L) raw apple cider into the jar. If the cider is very strong or sweet, add up to 2 cups of filtered water to lower sugar concentration and promote balanced fermentation. Stir in 2 tablespoons of granulated sugar to give yeast more fermentable food (this step is optional if using fresh cider with adequate natural sugars).

Add starter
Add 3 tablespoons of active mother of vinegar or 3 tablespoons of unpasteurized raw vinegar to inoculate. This introduces acetic acid bacteria that will convert alcohol to acetic acid.
- 5
Cover and ferment (alcoholic fermentation stage)
Cover the jar with cheesecloth or a breathable cloth secured with a rubber band to keep out insects and dust while allowing air exchange. Leave the jar at room temperature (65–75°F / 18–24°C). Over 1–3 weeks, natural yeast will ferment sugars into alcohol. Check weekly: you may see bubbling or a film (mother) forming. If fermentation stalls, a warmer spot may help.

Acetic fermentation stage
Once alcoholic fermentation slows (bubbling diminishes and liquid may smell like hard cider), transfer the liquid back to the jar if you sampled. Maintain the breathable cover and let it sit for 3–6 weeks to allow acetic acid bacteria to convert alcohol to vinegar. Taste every week starting at week 3 until you reach desired acidity. A developing cloudy mother is normal.

Strain and bottle
When vinegar has attained the desired sourness, remove any solids or excess mother with a fine mesh strainer. Decant into a clean 16 fl oz (473 ml) bottle or jars, leaving some headspace. Seal tightly.

Age and store
Optionally age the bottled vinegar in a cool, dark place for 2–4 weeks to mellow flavors. Store indefinitely at room temperature; refrigeration is unnecessary. Label with date and type.

Yield note
Starting with ~8–10 cups of liquid will yield roughly 16 fl oz of concentrated vinegar after evaporation and solids removal; adjust batch sizes accordingly if you want exactly 16 fl oz finished product.
