Answer: wine emphasized social divisions between its drinkers, as opposed to Ancient Greece, where guests drank as equals from a shared krater.
Explanation: The use of wine differed from that of beer in Greece and Rome in many different ways. For example, beer was used for the common people in societies who had switched to agriculture for certain reasons ( lack of food, wanted a steady supply of beer, and/or had to supply a growing population ). The reason it was for everyone and not exclusively for the rich was because beer was quite common and easy to make and was a great supplement to the diets of farmers who lacked in meat consumption. However, prior to the "golden age" of wine cultivation, Roman wine was reserved for the rich due to the fact that wine transport costed so much, and this caused wine to be concentrated in the hands of the rich. However, as wine cultivation became increasingly popular, everyone ( including slaves ) were allowed to, and even advised to, drink wine.
