Medieval brewing

Ale was a household product, and mostly women made it

Unhopped ale does not keep. It was made in small batches, drunk within a few days, and produced as part of ordinary household work — which in medieval England meant largely by women. A household that brewed more than it needed sold the surplus, and doing so was one of very few trades genuinely open to women, including married women who could trade on their own account.

This is well documented and it is the part of medieval brewing history most worth knowing. It is also the part that has recently been buried under a viral story about witches, which BeerHQ addresses separately and does not endorse.

Gruit, and what replaced it

Before hops became standard, ale was bittered and preserved with mixtures of herbs — bog myrtle, yarrow, marsh rosemary and others, varying by region. Gruit is the northern European name for such a mixture, and in several territories the right to sell it was a controlled monopoly, held by a lord or a church, and taxed.

That matters for how the shift to hops is usually told. Hops did displace gruit, and hops do preserve beer better; but where gruit was a taxable monopoly, adopting hops was also a way of escaping a levy, and the authorities holding the monopoly frequently resisted. The change had a fiscal dimension alongside the technical one, and telling it purely as brewers discovering a better bittering agent leaves out why it was contested.

Hops turn ale into a business

Hopped beer keeps. That single property changes the economics of the whole trade: beer that survives weeks rather than days can be brewed in large batches, stored, and shipped to somewhere it was not made. Hanseatic trade carried both the technique and the hops across northern Europe over several centuries.

In England the distinction was linguistic and fiscal as well as technical — "ale" meant the unhopped drink and "beer" the hopped one, they were regarded differently and taxed differently, and the two words did not merge for a long time. A reader who assumes the modern meanings will misread almost every English source before about 1600.

The commercialisation that followed is also what pushed women out. Larger batches needed premises, equipment and capital; selling at distance needed guild membership and trading rights. All three were structurally closed to women, so brewing became a male trade — for institutional and economic reasons that are visible in the records, and not for the reason currently circulating online.

Monasteries

Monastic houses brewed, at scale and seriously. They had grain from their own estates, buildings, continuity of technique, literate record-keeping, and an obligation of hospitality to travellers that had to be met with something drinkable. Daily allowances recorded in monastic sources are substantial by modern standards.

What monasteries did not do is invent beer, or brewing, or hopping, all of which are older or lay elsewhere. The specifically monastic contribution is closer to institutional: sustained practice, written records, and the scale that came from being a large landowner. The Trappist and abbey categories on modern shelves descend from this tradition but are considerably later and, in the Trappist case, tightly defined by a modern certification rather than by medieval continuity.
