Distribution from the Tavern for a happiness bonus. Your amount of wine served per hour determines the value of the bonus; larger Taverns allow serving more .
When being distributed, 1/3rd of your hourly ration is consumed every 20 minutes: at HH:00:00, HH:20:00 and HH:40:00 (server time). One full hour's ration is taken whenever you change the amount served in the Tavern. [1]
A Wine Press decreases Wine costs for all of these uses, except for Miracle donations, by 1%per level in the town it is built in.
A Winegrower increases the Wine production of a Vineyard by 2%per level in the town it is built in.
The Ikariam PlusWine production bonus is a separate process and does not affect the bonus from the Winegrower.
