An interesting sidenote to this is that the modern Greek word now used for undiluted wine, krasi (κρασί), originates from the krasis (κράσις, i.e. mixing) of wine and water in kraters. Kraters were glazed

Usage

At the beginning of each symposium a symposiarch (συμποσίαρχος), or "lord of the common drink", was elected by the participants. He would then assume control of the wine servants, and thus of the degree of wine dilution and how it changed during the party, and the rate of cup refills. The krater and how it was filled and emptied was thus the centerpiece of the symposiarch's authority. An astute symposiarch should be able to diagnose the degree of inebriation of his fellow symposiasts and make sure that the symposium progressed smoothly and without drunken excess.

Wine dilution

Drinking ákratos (undiluted) wine was considered a severe faux pas in ancient Greece, enough to characterize the drinker as a drunkard and someone who lacked restraint and principle. Ancient writers prescribed that a mixing ratio of 1:3 (wine to water) was optimal for long conversation, a ratio of 1:2 when fun was to be had, and 1:1 was really only suited for orgiastic revelry, to be indulged in very rarely, if at all. Since it is well-known that such mixtures would nowadays produce a rather unpalatable, watery drink, this certain practice of the ancients has led to speculation that ancient wines might have been vinified to a high alcoholic degree and sugar content, e.g. by using dehydrated grapes, and could withstand dilution with water better. Such wines would have also withstood time and the vagaries of transportation much better. Nevertheless the ancient writers offer scant details of ancient vinification methods, and therefore this theory, though plausible, remains unsupported by evidence.
