Oktoberfest, a major German cultural event with an estimated annual economic value of $1.5 billion, is facing legal challenges regarding its long-standing practices for beer sales and tent allocations. A key point of contention is the rule that only beer from six Munich "traditional breweries" can be served. This restriction, outlined in contracts between the city of Munich and tent operators, has led to accusations of cartel behavior, as it completely shuts out other breweries, even local ones like Giesinger Bräu. Critics argue that this arrangement, which allows breweries to supply beer and sometimes operate or lease tents, inflates prices, with a liter of beer now costing over $15, and benefits the city, which owns one of the permitted breweries and collects significant business taxes.

Adding to the controversy, the city's method of allocating the 35 beer tents (14 large and 21 small) is being challenged in court. A Munich couple, who were denied a large tent, argues that the allocation process violates EU procurement law, which would require an EU-wide tender for projects exceeding $5.4 million. They claim that the city's criteria for tent operators, such as prioritizing experience, ownership, and tradition, unfairly favor established local businesses. The city, however, maintains that the procurement law does not apply, partly because a previous requirement for continuous on-site presence by tent operators—a factor that could trigger procurement rules—was recently removed. This change has been described as a "legal maneuver" to avoid EU tendering requirements.

Despite an initial ruling by the Südbayern Procurement Chamber in favor of the city, the legal battle continues, with the Bavarian Supreme Court set to hear arguments on September 11. Critics, including legal experts, believe that the city's "flight into private law" to manage these contracts avoids administrative court scrutiny and prevents genuine competition. The "Vereinigung der Münchner Wiesnwirte" (Association of Munich Oktoberfest Restaurateurs) defends the current system, fearing that an EU-wide tender would lead to "unlimited commercialization" by multinational corporations and alter the festival's traditional character. However, opponents point out that several of the "traditional" Munich breweries are already owned by large international beverage conglomerates, such as Anheuser-Busch InBev and Heineken.
