Equipment

Improvising: what genuinely substitutes and what does not

What can I use instead of proper cider making equipment?

In short

Most of what a cider maker uses is a container, a tube or a lever, and those can be improvised freely as long as the materials are right and the thing can be cleaned.

A smaller set of items is not a shape but a specification: a bottle rated to hold pressure, a plastic certified for food contact, an instrument that has been calibrated. Substituting for those is not thrift, it is a change of outcome.

The three questions to ask of any substitute are whether the material is safe against an acidic alcoholic liquid, whether it can actually be cleaned, and whether it is being asked to hold pressure. Anything that fails the third is dangerous rather than merely unsatisfactory.

The principle behind the list

Cider is mildly acidic and, after fermentation, contains ethanol. Between them those two properties attack a surprising range of materials: acid dissolves zinc from galvanised surfaces, attacks aluminium and mild steel and takes copper into solution; ethanol is a far better solvent than water for the plasticisers, pigments and residues in plastics and coatings that were never intended to meet it. A material that is inert to water is not necessarily inert to cider, which is why the food-contact question is not a formality.

The cleaning question is the second filter and it eliminates more improvisations than the first. Anything with a hidden cavity, a thread, a rough weld, a scratched interior or a shape that cannot be reached will hold soil and organisms below the level any sanitiser will reach. A cheap tap with an internal void will be the dirtiest object in a cider house within a season, and no amount of chemistry will change that.

The pressure question is different in kind, because the failure mode is different in kind. A tainted batch is a disappointment; a glass container failing under internal pressure fragments and the fragments travel, and eye and hand injuries from this in home brewing and cider making are documented and are not rare. There is no version of this where a careful improviser gets away with it, because glass fails from a flaw rather than at a predictable pressure.

What substitutes and what does not

Common improvisations, judged
Instead ofWhat people useVerdict
A millFreezing and thawing the fruitWorks. Ice crystals rupture the cells and the thawed fruit gives up juice readily; it changes the colour and aroma and it needs freezer space
A millA food processor, or a mallet on fruit in a strong bagWorks for a few kilograms and becomes unbearable above that; very fine pulp may need a bag to press at all
A pressBoards, a car jack and a cloth-wrapped parcel of pomace in a crateWorks at small volume. The improvised frame is what fails, so keep loads modest, build for more force than you intend to use, and stand clear
A press clothAn old cotton sheet or a pillowcaseFails under load. A woven press cloth is cheap and a burst cloth loses the run and the pomace with it
A fermenting vesselA food-grade bucket with a sealing lid and a grommetWorks, and is what most people should use in preference to glass
A fermenting vesselA drum whose previous contents are unknownDoes not work. Solvents and aromatics partition into polyethylene and leach back into an alcoholic liquid for years
An airlockA length of tubing from the bung into a jar of waterWorks, and handles a vigorous ferment better than an airlock because it passes foam without blocking
An airlockA cloth over the neckWorks for a vigorous primary only. Once the gas stops it admits air and flies, which is exactly when protection is needed
A trial jarA tall straight-sided glass or a measuring cylinderWorks if the hydrometer floats free and does not touch the sides
A hydrometerNothingThere is no substitute. Guessing the gravity is guessing whether fermentation has finished, which is the decision that breaks bottles
A thermometerA cooking probe thermometer with a stainless tipWorks, if it is checked in an ice bath and the probe is sanitised
A racking caneA rigid tube with the intake held clear of the leesWorks. The standoff is the only clever part of a racking cane
A sanitiserBoiling water, on glass and stainlessWorks on things that can be filled or immersed; useless on a vessel too large to fill and damaging to most plastics
A sanitiserHousehold bleachPoor choice. It pits stainless steel and chlorine is a documented route to musty haloanisole taint in a cellar
Temperature controlA cold shed, a north wall, a tub of water around the vesselWorks, and is what temperature control amounts to at small scale
A pressure-rated bottleA still-wine bottle, a jam jar, a screw-cap bottle, a plastic milk bottleDoes not work and is dangerous. Nothing in this table matters as much as this row

What is never worth improvising

Pressure containment, for the reason above. If a cider is to be sparkling it goes into a bottle made and tested for sparkling wine or into a beer bottle at beer-range carbonation, closed with the closure that finish was designed for. If neither is available, the honest answer is to make the cider still.

Food-contact materials, because the failure is invisible and slow. A drum, a hose, a tap or a liner whose provenance cannot be established should not carry cider, and the money saved is trivially small against a batch.

Anything that produces a number destined for a label, a customer or a revenue authority. Alcoholic strength, sulphite declarations and volume statements are legal claims with tolerances behind them, and they are established by a method that will stand up rather than by arithmetic on a hydrometer reading.

And, less obviously, the cleaning and sanitising chemicals themselves. Substituting one product for another because it looks similar, or mixing two because one seemed weak, is how people are injured — an acid product and a chlorine product together release chlorine gas, and that has killed people in food premises.

Improvisation is the tradition, not a departure from it

Almost every piece of historic cider equipment was made locally from what was available: presses built by the estate carpenter, screws cut from apple wood, cloths woven from horsehair, casks bought second-hand from a trade that had finished with them. The idea that proper equipment is bought is recent and is largely a consequence of there being an industry to buy it from.

The other traditional answer to the capital problem is still the best one, and it is not improvisation but sharing. A community press, a mobile press that visits for a day, a neighbour’s mill, a group of people who between them own one of everything — all of these solve the problem that a press is a large object used one weekend a year. Borrowing capacity is almost always a better answer than owning a machine that will stand idle.

The last observation is about progression. Most people improvise at the start because they do not yet know which parts of the process they care about, which is exactly the right reason. What is worth buying properly reveals itself after a season or two, and it is rarely the press.

The one rule that admits no improvisation

Any container holding a cider that is carbonated, or that still contains fermentable sugar and live yeast, must be made for pressure. Glass fails from a scratch or a chip rather than at a predictable pressure, and when it fails it fragments. Use bottles sold for sparkling wine or for beer, matched to the carbonation intended and to the closure the finish takes; inspect every bottle and reject any that is chipped at the rim or scuffed; store bottle-conditioned cider cool and boxed, out of living space; and never bottle a cider whose gravity has not been stable for several days. If the right bottle is not available, make the cider still.
