Sextarius, a Roman measure for liquids…. This measure held two cotylae, or heminae, being about an English pint and a half…. The sextarius was also the sixth part of a congius, a liquid measure of ten libra in weight (about one gallon). It was the moderate quantity of wine which persons of sober habits drank at their meals…
That\’s (using American pints) .7 of a litre or so, or 4 ish of a standard modern glass of wine.
Nowadays, a standard glass of wine is served in a 175ml glass and is often up to 13% ABV, which adds up to 2.3 units.
Hmm, so a moderate quantity of wine which a person of sober habits would have with their meal was about 9 units.
We are told, for instance, that for women 14 units of alcohol a week is the recommended limit, and for men 21
So Roman women could have one and a half meals a week, Roman men two and a half.
No wonder they\’re all dead then.
