Posca — the Legions' Vinegar Drink
The drink of the Roman commoner and soldier: water mixed with wine vinegar, sometimes sweetened with a little honey and flavored with herbs. Refreshing, antiseptic, economical—the antithesis of the noble wine of banquets.

You think a soldier quenches his thirst with pure wine? That one I punish. In my camps, we drink posca: a dash of vinegar in water, that is all. It cuts thirst under the sun of Palmyra as well as in the mud of the Danube, and it straightens the murky water of the rivers we cross. A trickle of honey on victory days, a pinch of coriander, and that is already luxury. Keep your Falernian wine for the senators; I command men who march on posca.

Why this dish? Stagnant water killed more soldiers than the enemy; posca, slightly acidic, quenched thirst without intoxicating and sanitized dubious river water. Aurelian, who strictly rationed pure wine in his camps to maintain discipline, drank whole skins of it during his campaigns.

Ingredients (period version)
- Water — a cup (base)
- Wine vinegar (acetum) — a dash (acidity and sanitizing)
- Honey — a drop (optional) (sweeten)
- Crushed coriander seeds — a pinch (optional) (flavor)
Ingredients
- Fresh water — 250 ml (base)
- Red or white wine vinegar — 1 to 2 tablespoons (acidity)
- Honey — 1 teaspoon (optional) (balance)
- Lightly crushed coriander seeds — a pinch (optional) (flavor)
Method
- Pour the vinegar into the fresh water.
- Add the honey and stir until dissolved if you want a sweetened version.
- Flavor with a pinch of crushed coriander seeds and let infuse a few minutes.
- Strain if needed and drink well chilled. Adjust the acidity to taste: posca should tingle slightly, not burn.
How it was made : Posca was the standard drink of the legionary and the lower classes; the Gospel episode of the vinegar sponge offered to a condemned man refers to this common soldiers' drink. Its slight acidity limited bacterial growth in water, a major health asset on campaign before the knowledge of microbes.
The contemporary twist : Served over ice with a slice of cucumber, posca becomes an 'ancient switchel' perfect for summer—a shrub ahead of its time.
