How do you get wine on master of Olympus Zeus?

There are multiple ways to get wine :

* producing it : by producing the grapes and the wine or by buying the grapes and making the wine

* buying the wine from another city : the wine is an luxury and therefore expensive

* asking it from another city : you must have good relation with the city you are asking from

* raiding a city : you must have an army to raid

* receiving it as a present : usually this is when you cannot do any of the above and the game will give wine to you through an offer from a city. You must be careful not to consume the wine or sell it by mistake for the game will only give you the amount needed. Have fun !
