Is pineapple beer actually alcoholic?

Yes, but only lightly. A 2–4 day ferment usually lands somewhere around 1–3% ABV — closer to a kombucha or a light shandy than a lager. The alcohol stays low because you drink it young, before the yeast has time to convert all the sugar. The longer you leave it, the stronger and drier it gets.

Do you use the pineapple skin?

Yes. The skin is the point. Wild yeast and flavour compounds sit on and just under the peel, so traditional recipes chop the whole fruit — skin, core and flesh — straight into the bucket. Scrub the outside well first to remove dirt, then use all of it. Many cooks make the beer specifically to use up the peel after eating the flesh.

How long does pineapple beer take to ferment?

Two to four days at warm room temperature (about 24–28°C / 75–82°F). You'll see a foamy, bubbly head form within a day. Most people strain and drink it at 2–3 days while it's sweet and gently fizzy. Past 4–5 days it turns drier, more sour and more alcoholic.

What do the raisins do?

Raisins feed the ferment and add body and a rounder, wine-like note. They also carry their own wild yeast. As they ferment they fill with gas and bob to the surface — an old rule of thumb says the beer is ready when the raisins float. They're optional but traditional.

Why does my pineapple beer bottle keep exploding?

Because it's still alive. Active yeast keeps producing CO2, and a tightly capped bottle has nowhere to vent it, so pressure builds until the bottle bursts. Bottle only once fermentation has slowed, leave the caps loose or 'burp' bottles daily, refrigerate to slow the yeast, and drink within a few days. Never store sealed at room temperature.

Do I need special beer yeast?

No. Plain instant or active dry baking yeast works and is what most traditional recipes call for. The pineapple skin and raisins also bring wild yeast, so some versions use no added yeast at all — they just take a little longer to get going.

How should I serve and store it?

Serve it cold over ice, well strained. It's a fresh drink, not a keeper — flavour is best in the first day or two after straining. Keep it in the fridge in loosely capped bottles and finish the batch within about 3–4 days.

Pineapple Beer & Quash Beer — Ferment Calculator

Pineapple beer is a fast, home-brewed drink made by fermenting a whole pineapple — skin included — with sugar, water, raisins and a pinch of yeast for just a few days. It comes out sweet, fizzy and only lightly alcoholic, and it’s one of the easiest ferments a beginner can make.

What is pineapple beer (quash)?

Pineapple beer is a traditional home brew found across Southern Africa, where it’s often called quash. It sits somewhere between a beer, a cider and a soft drink: naturally carbonated, tropical and tangy, with a modest alcohol kick. Unlike lager or ale, there’s no boiling, no malt and no long conditioning — you build it in a bucket and drink it within the week.

The flavour is bright and juicy up front, with a gentle sourness that grows the longer it ferments. Because it’s drunk young, it keeps much of the raw pineapple’s sweetness. Think of it as the pineapple cousin of ginger beer or Mexican tepache — a quick, everyday brew rather than a cellared one.

Does it use the pineapple skin?

Yes — and that’s the whole trick. The skin does most of the work.

Wild yeast lives on the peel The skin carries natural yeast and bacteria that kick-start fermentation, which is why even no-added-yeast versions still bubble away happily.

Flavour is concentrated at the surface Aromatic oils and sugars sit in and just under the rind, so fermenting the whole fruit gives a deeper pineapple flavour than juice alone.

Scrub before you chop The outside collects field dirt and residue. Rinse and scrub the peel well under running water, but do not peel it — chop skin, core and flesh together.

Traditionally the beer is often made from the peel and core left over after eating the flesh, which makes it a thrifty, waste-free brew. If you want a stronger pineapple hit, use the whole fruit.

What you'll need

A single batch is roughly one large pineapple to every 2–3 litres of water. This makes about 6 litres:

2 ripe pineapples, skin on

5 cups white sugar

6 L lukewarm water

You’ll also need 1 cup of raisins (lightly bruised), 2–3 teaspoons of instant dry yeast, a large food-grade plastic bucket (about 10 litres), a piece of cloth or tulle to cover it, and a strainer. That’s it — no airlock, no thermometer required, no special equipment.

Ripe fruit matters most: a fragrant, slightly soft pineapple has the most sugar and the best flavour. Under-ripe fruit ferments slowly and tastes thin.

How to make it, step by step

The process is forgiving. Keep everything clean, keep it warm, and don’t seal it.

1
Chop the whole pineapple Cut off the leafy crown, scrub the skin, then roughly chop each pineapple — skin, core and all — into chunks and drop them into a clean bucket.
2
Add sugar, water and raisins Pour in the lukewarm (not hot) water, add the sugar and bruised raisins, and stir until the sugar dissolves. Lukewarm water helps the sugar dissolve and wakes the yeast without killing it.
3
Pitch the yeast Sprinkle the yeast over the surface, wait about a minute, then stir it through. If you are going fully traditional with no added yeast, just rely on the wild yeast from the skin and raisins.
4
Cover loosely Lay a cloth or tulle over the bucket and secure it with string or a rubber band. This keeps out flies and dust while letting CO2 escape. Do NOT use an airtight lid.
5
Ferment warm and stir Leave it somewhere warm and dark and stir twice a day. Within a day it should be foaming and smelling yeasty and fruity. Let it work for 2–4 days.
6
Strain and bottle When it tastes right — lightly fizzy, faintly boozy, still a little sweet — strain out the pineapple and raisins. Bottle the liquid, chill it, and leave caps loose for the first several hours.

Ferment time and how strong it gets

Pineapple beer is a sprint, not a marathon. Warmth drives the speed, and the finish point is a matter of taste — pull it early for a sweeter, softer drink, or later for something drier and stronger.

2 days sweet, gently fizzy, ~1% ABV

3 days balanced, tangy, ~2% ABV

4+ days dry, sour, stronger, 3%+

The alcohol stays modest for one simple reason: you drink it young. Yeast turns sugar into alcohol and CO2 over time, so a batch stopped at 2–4 days has only converted a fraction of its sugar — most recipes land around 1–3% ABV. Leave it a week or more and it will keep climbing, getting drier and more sour as it goes. These are eyeball estimates; a hydrometer reading before and after gives you a real number.

Straining and serving

Once it’s fermented to your liking, strain the liquid off the solids through a sieve or muslin — the pineapple chunks and raisins have given all they’ve got and will only make the beer cloudy and bitter if left in.

Serve it cold, over ice, ideally within a day or two of straining. Pineapple beer is a fresh drink at its best straight after it’s ready; it doesn’t age or improve in the bottle. If you like it fizzier, a short chilled rest before serving builds a little more natural carbonation — just keep an eye on the pressure (see below). It’s a naturally cloudy, rustic drink, so don’t expect it to be crystal clear.

A safety note on carbonation

The one real risk with pineapple beer is pressure. Live yeast keeps making CO2 after you bottle, and a sealed bottle has nowhere for that gas to go — so it builds until the bottle can burst. Home brewers regularly report pineapple beer bottles exploding in cupboards and fridges.

×Never store tightly sealed bottles at room temperature while the beer is still active
×Use plastic bottles you can feel go rock-hard, not glass, if you are unsure
×Bottle only once the vigorous fermentation has calmed down
×"Burp" caps daily to release pressure, or leave them slightly loose
×Refrigerate to slow the yeast right down, and drink the batch within 3–4 days

Fermentation is also why you never use an airtight lid on the fermenting bucket. Keep it loosely covered, keep bottles cold and vented, and finish the batch quickly. Treat it as the short-lived, fresh drink it is and you’ll never have a problem.
