Dwarven Ale

Dwarven Ale is a beverage available at merchants throughout the Shiverpeak Mountains for 200 gold. Drinking it will cause the screen to temporarily blur and erratically zoom in and out. Beware drinking several tankards in rapid succession as that will result in loss of balance, loss of dignity, declarations of love, and general hilarity for everyone else watching.

Currently the only use for Dwarven Ale is to get the Drunkard title.

Levels of drunkenness
There are 6 levels of drunkenness distinguishable when dealing with Dwarven Ale. When you did not drink any kind of alcohol you are at level 0. For each ale drunk in a row you ascend one level until you reach the highest level. After that drinking ale has no effect besides the waste of money. Every minute you will automatically descent one level until you reach level 0. With every descent you will earn 1 minute towards Drunkard title.

As you can see it is most efficient to stay within level 2 and 5 to gain the Drunkard title. E.g. you could drink 5 ales in a row then wait for 3 minutes so that you drop to level 2. Then you have to drink another 3 ales to get back to level 5 and so on.
