Dionysos

The god of wine and beer. Dionysos is the god of joy and the freedom from work. The gospel of  Dionysos is simple: "Enjoy life", "Reap the fruits of your work", "Drink water to survive, drink wine to live". For most people, toil and hard work are necessary to survive. But survival has no point, if there is no joy. So joy is good, as it rewards and motivates hard work. Thus joy propagates life. And though joy is found in many places, none are sure but intoxication. Intoxication causes ecstasy, and if you drink without any other intention than enjoyment, there will be no hang-over. Dionysos does not have many followers dedicated solely to him, for it is only in rare cases that he is worshiped by a single person. He is worshiped in groups, most flamboyantly in the festivals being held up to three times a year, depending on local tradition. He is also quietly toasted at the inn, when the men get a drink after hours, before heading home to the wife and kids. Dionysos is also celebrated as the god of old age, as some consider him is the only god that guarantees a happy life as an old man. These worshipers sacrifice regularly and pray that they will continue to enjoy drinking till they die.
