Whats on your list of "Must brews?"

[PasbitinusBluinusRibbinus]

There is a very interesting number of brews on here that are HBT legends, like Alpfwein, Haus Ale, and Skeeter Pee. If someone asks me to suggest something for their first exploration in fermentation, it's always alpfwein.

Does anyone have any other must-brews? It can be beer, cider, wine, whatever, just a drink so well received that everyone should make it once.
