Dry Hard Cider

Equipment Required

• Glass carboy or fermentation jug (1 gallon to start, or 5 gallon)
• Airlock and bung
• Sanitizer (Star San)
• Auto-siphon and tubing
• Hydrometer (optional but recommended)
• Bottles and caps or swing-top bottles

Ingredients

• 1 gallon fresh apple juice or unfiltered apple cider (no preservatives — avoid potassium sorbate and sodium benzoate)
• 1 packet Safcider AS-2 or Lalvin EC-1118 yeast
• Optional: 0.5 cup brown sugar (to boost ABV by ~1%)
• Optional: 0.5 tsp yeast nutrient
• Sanitizer for equipment

Method

1. Choose your juice. This is the most important step. Read the label — the juice must not contain potassium sorbate or sodium benzoate, which are preservatives that prevent fermentation by inhibiting yeast. Ascorbic acid (vitamin C) is fine. Pasteurized juice works perfectly. For the best flavor, use fresh-pressed cider from an orchard or farmers market — the blend of apple varieties creates complexity.

2. Sanitize and pitch. Sanitize a 1-gallon glass jug and airlock. Pour out (or drink) about 1 cup of juice to create headspace for fermentation foam. If using brown sugar, dissolve it in the removed juice, warm gently, and pour it back. Sprinkle the yeast directly into the jug. Attach the airlock. That is it — you have just started making alcohol.

3. Ferment (10–14 days). Place the jug in a dark spot at 60–72°F. Within 24 hours, you will see bubbles in the airlock — each bubble is CO2 escaping as yeast converts fructose and glucose into ethanol. Fermentation will be vigorous for 3–5 days, then slow. After 10 days, the cider will be visibly clearer and the airlock will bubble only occasionally.

4. Taste and decide. After 14 days, taste the cider. It will be dry — the yeast has consumed nearly all the sugar. If you want it sweeter, you have two options: (a) back-sweeten with apple juice concentrate after adding potassium sorbate to prevent refermentation, or (b) cold crash the jug in the refrigerator for 48 hours to drop the yeast out, then drink it young and slightly sweet.

5. Bottle or drink. For still cider, siphon into sanitized bottles and refrigerate. For carbonated cider, add 1 tsp sugar per 16 oz bottle, cap tightly, and leave at room temperature for 3–5 days. Refrigerate before opening — the carbonation can be vigorous. Your cider will be approximately 5–6% ABV (or 6–7% with the brown sugar addition).

What You're Practicing

Hard cider is fermentation stripped to its essence — sugar, water, yeast, time. There is nowhere to hide mistakes, which makes it the ideal learning project. You are observing yeast metabolism in real time: Saccharomyces cerevisiae consumes simple sugars (glucose and fructose) and produces ethanol and CO2 as metabolic byproducts. The preservative check teaches you about antimicrobial chemistry — sorbate inhibits yeast cell membrane function, which is why it prevents fermentation. Temperature affects fermentation speed and flavor: cooler temps produce cleaner, more apple-forward cider; warmer temps ferment faster but can produce fusel alcohols (harsh, hot flavors). The back-sweetening decision introduces you to residual sugar management — the same concept that distinguishes dry from sweet wine. This is the foundation of all Fermentation Science. If you can make cider, you can make anything.
