A Bierkeller in Franconia is a beer garden built above a historic underground sandstone vault. Biergarten is the more general term used mainly in southern Bavaria. In Franconia the term Bierkeller is used almost universally for outdoor drinking spots — even when referring to the garden above, not the cellar below. The informal boundary between the two terms is called the "Bierkeller Equator."
Short Version
- Bierkeller: the historic underground storage cellar where beer was lagered
- Biergarten: the outdoor seating area above or next to the cellar
- In Franconia: "Keller" often means both — the whole complex
- Without a cellar underneath: it's just a Biergarten, not a Bierkeller
What Is a Bierkeller?
A Bierkeller is first of all exactly what the word says: a cellar for beer. Specifically: a room driven into rock or earth, maintaining a stable cool temperature year-round. In Fränkische Schweiz — built into limestone formations — these cellars hold temperatures between 8 and 12 degrees Celsius throughout the year. Before mechanical refrigeration, this was the only way to store lager beer through summer.
From the necessity of storing beer underground grew the tradition of drinking outside: if you're going to the cellar to fetch beer anyway, you might as well drink outside in front of it. The outdoor areas emerged — first as functional side effects, then as a tradition in their own right.
What Is a Biergarten?
The Biergarten is the outdoor area. Originally: the garden in front of or above the Bierkeller. Today: any outdoor hospitality area serving beer can technically call itself a Biergarten. In Munich, "Biergarten" usually means a large, well-organised outdoor area under chestnut trees — often without a historic cellar underneath at all.
In Franconia it is different. When a Franconian says "going to the Keller", they mean the outdoor area of a brewery — because that outdoor area is historically connected to the cellar and has always been called "the cellar", not "the garden".
The Bread-and-Snacks Question
In many Franconian Bierkeller, bringing your own food is permitted — but not everywhere. The prevailing rule: drinks are bought from the operator; food may be brought in if the operator permits it. Always ask first. A polite question causes no offence. An uninvited large picnic spread might.
