Apple juice and apple cider start from the same fruit — the difference is how far the juice is processed, and which country you’re standing in when you name it. For a home brewer, that distinction barely matters: what matters is buying 100% apple with no fermentation-stopping preservatives. Here’s how the two compare, how to swap them, and how to turn a jug of juice into hard cider or cyser.
Apple juice vs apple cider: the real difference
In the United States, the split is about processing, not alcohol. Both drinks are non-alcoholic — one is just closer to the raw pressed fruit than the other.
Apple cider (US) — raw, unfiltered pressed apple — cloudy, with fine pulp and sediment. Fresh or lightly pasteurized, a shorter shelf life, and a fuller, more tart apple flavour.
Apple juice (US) — filtered to remove pulp, then pasteurized for a clear, shelf-stable drink. Often sweeter, sometimes from concentrate, and stores for months unopened.
Taste & body — cider is tannic and complex; juice is smoother and sweeter. Once fermented, cider tends to give a rounder hard cider and juice a cleaner, crisper one.
The line is blurry in the store — some “cider” is pasteurized and some “juice” is cloudy — so always read the ingredients rather than trusting the label word.
US vs UK: why 'cider' can mean alcoholic
The same word points at two very different drinks depending on the country, which is a common source of confusion in recipes and forums.
Can you brew hard cider from store-bought juice?
Yes — this is one of the easiest ways to start brewing, and cheap supermarket juice makes perfectly good hard cider. The single rule is that the juice must be able to ferment, which comes down to what’s in it. Buy 100% apple juice with nothing added that’s designed to kill or inhibit yeast.
- ×Potassium sorbate — a preservative that stops yeast reproducing; fermentation will stall or never start
- ×Sodium benzoate (and benzoic acid) — an antimicrobial that inhibits yeast the same way
- ×Juice labelled "not from concentrate" but with added sorbate/benzoate — still will not ferment
- ×"Apple drink," "cocktail," or "-ade" — often watered down with added sugar and flavouring, not 100% apple
Ascorbic acid (vitamin C) and citric acid are fine — they’re antioxidants, not fermentation inhibitors. Pasteurization is also fine: heat pasteurization kills microbes at the time but leaves nothing behind to stop the yeast you pitch later. The only true dealbreakers are the sorbate and benzoate preservatives.
What to look for on the label
Turn the bottle around and read the ingredients before you buy. A brew-ready juice is short and boring on the label.
Ingredients: apple juice (and maybe vitamin C) — ideal — ferments cleanly with any cider or wine yeast.
From concentrate, no preservatives — works fine; flavour is a touch thinner than fresh-pressed but ferments the same.
Contains potassium sorbate or sodium benzoate — will not ferment — leave it on the shelf.
"Fresh cider," unpasteurized — ferments, but carries wild yeast and bacteria; treat with a Campden tablet first for a predictable result.
Cloudy, preservative-free juice or fresh cider gives the most apple character. Clear filtered juice ferments just as reliably and is usually the cheapest per litre.
Substituting one for the other
Whether you can swap juice for cider depends on what you’re making. The two are close, but not identical.
What is cyser?
Cyser is a mead — but instead of fermenting honey with water, you ferment honey with apple juice or cider. The result sits between hard cider and traditional mead: unmistakably apple, but with the body, floral aroma and higher strength that honey brings.
Because you’re adding a concentrated sugar (honey) on top of the sugar already in the juice, cyser starts at a much higher gravity than plain cider, and finishes stronger. Typical numbers:
Plain hard cider from unsweetened juice usually starts near 1.045–1.055 and finishes around 5–7% ABV. Adding honey is what turns it into cyser and pushes the alcohol up. Use your starting and finishing gravity to read the exact number.
How to make a simple cyser
A one-gallon (4 litre) batch is the easiest way to start. You need preservative-free 100% apple juice, honey, a fermenter with an airlock, and a wine or cider yeast (a neutral one like Lalvin 71B or a champagne yeast both work well).
- 1Sanitize everything Clean and sanitize the fermenter, airlock, spoon and anything else the juice will touch. Contamination is the main thing that ruins a batch.
- 2Warm and dissolve the honey Gently warm 1 to 1.5 kg (2–3 lb) of honey with a litre of the apple juice until it dissolves fully. Don't boil — you'll drive off the aroma. Let it cool to room temperature.
- 3Combine and check gravity Pour the honey mix and the rest of the juice into the fermenter, leaving headspace. Aim for roughly 4 litres total. Take a hydrometer reading — you're looking for about 1.075–1.100. Record it; you need it to work out ABV later.
- 4Pitch the yeast Rehydrate the yeast per its packet, then stir it in. Optionally add yeast nutrient — honey is low in nitrogen, so nutrient helps the ferment finish cleanly. Fit the airlock.
- 5Ferment Keep it at 18–22°C (64–72°F), out of direct light. Active bubbling starts within a day or two and slows over 2–4 weeks as the sugar is consumed.
- 6Rack, age and bottle When the gravity is stable for several days (often near 0.995–1.005), siphon off the sediment into a clean vessel. Age at least a month — cyser is harsh young and mellows beautifully. Take a final gravity reading before bottling.
Plug in your original and final gravity to get exact alcohol by volume.
Common mistakes to avoid
Most failed first batches come down to a handful of avoidable errors — nearly all about ingredients or sanitation rather than skill.
- ×Buying juice with sorbate or benzoate — it simply will not ferment, and there is no rescue
- ×Skipping sanitation — an off, vinegary batch is almost always contamination
- ×Boiling the honey — it strips out the aroma that makes cyser worth making
- ×Bottling before fermentation finishes — trapped CO2 in sealed bottles can build up and cause bottle bombs
- ×Drinking it too young — both hard cider and cyser taste raw for the first few weeks and improve with a month or two of aging
