Pineapple Beer & Quash Beer

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.

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

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.

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

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.

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

1. 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. 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. 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. 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. 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. 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.

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.

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.

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.

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.

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.
