In the Harry Potter series, Butterbeer is a popular wizard drink. Sold in a corked glass bottle, Butterbeer is pleasant-tasting, and due to its incredibly low alcohol content, it may safely and legally be purchased and consumed by any wizard of any age. However, due to what seems to be a very low biological tolerance to alcohol, Butterbeer is hard booze to house-elves.

Butterbeer has no magical properties, so it is indicative of wizard culture far more than magic.
