Made by bottling the contents of a fermented wine barrel in a glass jar, this is a portable container of wine. You may either drink the whole bottle yourself (special menu->consume->(pick wine in inventory), or take it to a ceremonial tasting table where you can share it with 6 other people. Drinking wine may increase your Oenology and eventually give you increased perception. When drunk, you will get a glass jar back.
A complex item, wine is listed in inventory as "wine:<guild>'<vintage>", where <guild> is the name of the guild owning the barrel, or the barrel label and <vintage> is set by the vintage of the grapes in the barrel (weighted average plus a small random variation that can change each time, if they're mixed vintage).
Current vintage: '54
