How cider knowledge was passed on

Brewing, coopering, milling and baking were trades: they had defined entry, a term of apprenticeship, recognised competence and, in many places, an institution enforcing standards. Cider making had none of these anywhere in Britain, and the position in Normandy and northern Spain was broadly comparable — farm making was farm work, and the specialist roles that existed were around the equipment rather than around the drink.

The absence of a formal structure meant no curriculum, no examination and no external standard, and it meant enormous variation. Farms a mile apart made cider by different methods with different results, and neither had any way of knowing whether their practice was good beyond the opinion of the people who drank it.

It also meant no written record. A trade with an apprenticeship generates documents; a household practice does not. What is known about how cider was actually made on farms before the twentieth century comes from the technical writers, from the equipment, and from oral accounts collected late — never from the ordinary transmission itself, which left nothing behind.

The content of the knowledge is worth specifying, because it is not what a modern reader might assume. Little of it was procedural in the sense that a recipe is. Most of it was judgement about particular states: whether fruit gathered a fortnight ago is ready to mill, whether the pomace is milled finely enough for this year’s fruit, whether a cask smells sound, whether a ferment is going too fast, whether it is time to rack.

Judgements of that kind are tacit. They are made by smell, by touch, by the sound of a cask and the look of a surface, and the person making them frequently cannot say how. This is exactly the difficulty the seventeenth-century writers ran into: their books are detailed about equipment and vague about the moments that matter, because the moments that matter were not verbalisable with the vocabulary available.

The corollary is that written instruction was a poor substitute even when it existed. A book can say to rack when the fermentation slows; it cannot convey what that looks like in a particular cellar with a particular fruit, and the person who knew was standing next to you or was not.

Transmission was also material. A person taking over a holding inherited the mill, the press, the casks, the cellar and its resident microflora, and with them a set of constraints that shaped what could be made. The practice was fitted to the equipment, and the equipment persisted for generations.

That is one reason regional differences were so durable. A district in which everyone used a particular kind of press, particular vessels and particular fruit produced a particular kind of cider, and a person learning in that district learned that kind, not cider in general. Regional style, in this reading, is partly the accumulated consequence of who taught whom in a small area.

It also explains a specific vulnerability. When the vessels changed — when a farm replaced wooden casks with steel or plastic — some of what had been transmitted stopped applying, and the older maker’s judgements about cask condition, topping up and cellar management became advice for equipment nobody had any more.

Farm cider making contracted sharply through the middle of the twentieth century for reasons of agricultural economics, and with it the ordinary occasion for learning. A person who did not make cider in the autumn did not teach anybody to make cider, and the interruption was measured in decades in most districts.

The revival that began in the 1970s therefore had to reconstruct rather than continue. Its sources were the surviving technical literature, the twentieth-century research output, a small number of old makers who were sought out and recorded, and — importantly — practice borrowed from brewing and from winemaking, which had continuous professional traditions and published methods.

This is why modern small-scale cider making is more explicitly technical than its predecessor. It measures gravity, acidity and sulphur dioxide, because the tacit judgements those measurements replace were not available to be learned. The instruments are not a modern affectation; they are what you use when the person who could tell by smell is not there.

What exists now is a patchwork of explicit instruction: short courses run by associations and by producers, published handbooks aimed at small-scale and at commercial making, technical texts on production and quality control, university programmes in cider-producing regions outside Britain, and structured judging frameworks that teach a vocabulary for what is in the glass.

The gain is transferability. Explicit knowledge can be taught to someone with no family connection to an orchard, checked against evidence, argued about, and improved. The modern sector is populated almost entirely by people who came to cider from outside it, and that would be impossible under the old transmission.

The loss is specificity. What written instruction transmits well is the general case, and what it transmits badly is the local one — this fruit, this cellar, this year. Some of what was in the old transmission was not superstition or habit but genuine local knowledge, and where a district’s practice went unrecorded it has not been replaced by anything.
