Wiesnbräu

 is an item bought from the Merchant during the Oktoberfest Update. It behaves very similarly to ale, but also adds the Potion Sickness debuff, which doesn't start counting down until the effects of the item wear off. This means that it effectively adds 30 seconds to the regular Potion Sickness debuff.

Trivia

 * It is the only consumable to cause the Potion Sickness debuff without restoring any health.
