The most popular non-alcoholic drink in ancient Rome, appreciated by both citizens and legionaries. It was a vinegar water made from diluted vinegar
(wine vinegar). The finely acidic taste had a refreshing effect and also masked the taste or smell of water of inferior quality. In addition to the posca produced from wine vinegar (which, as mentioned, was alcohol-free), wine that had become acid or iora
(marc wine) was also used for production. Wine vinegar was added for this purpose. Posca became known through the Gospels in the New Testament of the Bible
, although it is not explicitly mentioned there. When Jesus was hanging on the cross, a soldier (different in the Bible translations) gave him wine mixed with bile, vinegar or vinegar water with a sponge impaled on a lance. Most likely, the legionary in question resorted to what he had in his canteen, namely posca. This was thus an attempt to refresh the sufferer and not a torture usually interpreted in this way.
