The most popular non-alcoholic drink in ancient Rome, appreciated by both citizens and legionnaires. It was a vinegar water made from diluted vinegar
(Wine vinegar) was produced. The fine-sour taste had a refreshing effect and also covered the taste or smell of water of inferior quality. In addition to the produced from wine vinegar Posca (which, as I said, was non-alcoholic) was also turned sour wine or iora
(Pomace wine) used for production. For this purpose wine vinegar was added. The 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 mixed it with bile, vinegar or vinegar with sponge speared on a lance. Most likely, the legionnaire in question grabbed what he had in the flask, Posca. This was therefore an attempt to refresh the sufferer and not usually interpreted as torture.
In the famous "Historia Augusta" (late antique collection of about 30 imperial biographies) is told how an emperor (for example, handed down to Trajan and Hadrian) approaches the "simple man or soldier". After personally grinding corn in the camp with a hand mill in front of the Legionnaires and baking a simple soldier's whole wheat bread in the fire, he does not allow himself to be rinsed down with more expensive wine, but rather the simple drink of the legionaries, the Posca , He drinks the sour drink to the men and wins their hearts. Legionnaires should think, "The Emperor is one of us, he eats and drinks the same as us!"
