Oktoberfest Pours Beer From Only Six Munich Breweries. One Craft Brewer Raised €12.4 Million to Dig a Well and Get In
The rules, including a 1487 purity law that even specifies well water from inside city limits, have kept the same six breweries in the tents for decades. It’s the most drinkable lesson in moats you’ll find all month.

Key Points
Only six established Munich breweries have supplied Oktoberfest’s beer for decades, all brewing under a 1487 purity law that even requires well water from inside city limits.
Craft brewer Steffen Marx of Giesinger Bräu spent two years getting a drilling permit, raised €12.4 million to dig his own well, and has 21,000 of the 35,000 signatures needed to force a citywide referendum.
A restaurant’s lawsuit over tent-bidding rules that award points for tradition goes before Bavaria’s Supreme Court this month.
About 6.7 million visitors are expected from Sept. 19, bringing roughly $1.8 billion into the local economy.
Some tents charged €15.80 a liter last year, about 30% above typical central-Munich prices, and dirndls and lederhosen became the dress code only in the 1990s.

Oktoberfest opens Sept. 19 in Munich, where a handful of long-established local breweries supply all the beer, and the rules on who gets in are being tested in court and by a referendum petition.
In one line: Oktoberfest’s six-brewery lineup is a moat written into the rules, and the €15.80 liter is what pricing power looks like, right up until someone changes the rules.
Want to pour beer at Oktoberfest? It’s simple. Be one of six established Munich breweries, and brew under a purity law from 1487 that even specifies the water — it’s got to come from a well inside city limits. Craft brewer Steffen Marx took that second part literally. He spent two years getting a drilling permit, raised €12.4 million to dig his own well, and is now collecting signatures, 21,000 of the 35,000 he needs, to force a citywide referendum so his Giesinger Bräu can be poured next year.
Tradition, or a very old cartel?
Organizers call the arrangement tradition; critics call it a cartel. A restaurant that sued the city over tent-bidding rules awarding points for tradition goes before Bavaria’s Supreme Court this month, arguing that open bidding across the EU would bring prices down. The old tent families answer with visions of foreign beer and döner stands. Some of the heritage isn’t as old as it looks — dirndls and lederhosen only became the dress code in the 1990s — but the rules are sturdy enough that even the Prince of Bavaria, whose family started the whole festival, lost in court trying to get his beer in.
What a moat really is
Investors love the word moat. Munich serves one by the liter. A moat is often nothing more than a rule that keeps competitors out, and with 6.7 million visitors expected from Sept. 19 and about $1.8 billion flowing into the local economy, this rule is worth a fortune. It helps explain how some tents charged €15.80 a liter last year, roughly 30% above typical central-Munich prices. That’s pricing power with foam on top. And it tends to last exactly as long as the rule does.
Index investors own the incumbents almost by definition, and some of their advantages look a lot like a spot in the tents. So here’s a good question for any holding: which of its advantages are products customers keep choosing, and which are laws someone could rewrite? Products have to keep winning; laws don’t, until a court, a regulator or a petition with 35,000 signatures undoes them. Bring the list of your ten largest positions — it’s a pleasant fifteen minutes, ideally with a pretzel.
What It Means For Your Portfolio
Hold — ask which advantages are laws, not products
A moat that rests on a rule is only as durable as the rule, so the useful question for any holding is which advantages customers choose and which ones a court, a regulator or a referendum could take away.
General planning principles, not advice for anyone in particular: pricing power backed by regulation, licensing or tradition can be very profitable while it lasts, and it can end on a court date rather than with a sales miss. Diversified investors own many such incumbents by design, which is one more reason not to lean too hard on any single protected franchise.
In the book, there’s no position here — no brewer and nothing tied to the festival — and nothing is being bought or sold ahead of Friday’s inflation report. The moat question applies to every holding, though: which advantages are products and which are permissions, and how the portfolio would look if a permission were withdrawn.
