I had a player start a tavern and called his local beer- Bob's Booze, mostly in remembrance of his 3 dead brothers. He was Bob IV and his brothers were Bob, Bob Jr, and Bob Jr Jr.
Minotaur's Maze- For those who want to get drunk and forget where they are. Black Dragon Stout- A common black ale in my games. Although most of the beers are just called black, brown, gold, and local.
Sex on the Kobold - a fruity drink from distilled peaches (or tropical fruits) with a bunch of ground raw grain on the bottom. Troglodyte Fart - A mix of whiskey and fermented mushrooms that despite the atrocious smells is popular because of how cheap it is and the ease of which one can get drunk and/or have hallucinations.
Mushroom Scrumpy - a favourite of gnomes, brewed from apples and mushrooms
Mushroom Lager - another gnome brew
Strawberry Xuxu - brewed by pixies
Cloudberry Liquer
Sloe Gin
Green Fairy
