Ingredients

Malted barley (barley that has been sprouted and dried) — 500 g (1.1 lb)
Water — 3 L (12 cups)
A small amount of a natural yeast or fermentation starter

Method

Bring the water to a simmer in the pot and add the malted barley.
Simmer for 1-1.5 hours, stirring occasionally, until the liquid takes on a sweet, malty aroma.
Strain through cloth into a clean fermentation vessel, pressing to extract as much liquid as possible; discard the solids.
Cool the strained liquid to room temperature, then add the yeast or fermentation starter.
Cover loosely and leave to ferment at room temperature for 3-5 days, tasting periodically, until it reaches a mildly alcoholic result.
Strain again if needed and serve at room temperature or lightly chilled.

Introduction: A mildly alcoholic barley beer, described directly by the Greek observer Posidonius as the everyday drink of poorer Gauls, in contrast to the imported wine favoured by the wealthy.

Cultural Background: Posidonius, as quoted by Athenaeus, directly describes the Gauls drinking a barley-based beer he records under a term rendered variously as korma or zythos, specifically noting that this was the drink of ordinary and poorer Gauls, while wealthier Gauls instead drank imported Italian wine; this is one of the more directly attested details in this entire collection, coming from a named ancient source describing an actual named beverage.

Tips: – Malted barley (rather than plain barley) is essential, as the malting process converts starches into sugars the yeast can ferment. – Fermentation time varies with ambient temperature; taste from day 3 onward and refrigerate once the flavour suits your preference.

Variations: – Honey can be added during the initial simmering for a sweeter variant. – A shorter fermentation gives a milder, less alcoholic result.

Storage: Refrigerate fermented beer in a covered container and consume within a week.

Reheating: Not applicable; this is a cold or room-temperature beverage.

FAQs:

Q: Is this beer directly attested in an ancient source?

A: Yes, Posidonius, as preserved through later quotation by Athenaeus, directly describes ordinary Gauls drinking a barley-based beer under a term rendered as korma or zythos, making this one of the more directly documented drinks in the entire continental Celtic collection.

Q: Why did wealthy Gauls drink wine instead?

A: Posidonius specifically contrasts poorer Gauls’ beer-drinking with wealthier Gauls’ preference for imported Italian wine, a distinction also supported by archaeological finds such as the Vix Krater and Hochdorf burial, both associated with elite Gallic wine consumption.
