The Bavarian cheese spread served with pretzels at Oktoberfest is Obatzda.
Obatzda is a soft, savory cheese mixture traditionally made by blending ripe Camembert or another soft cheese with butter. Paprika gives it its characteristic orange color, while salt, pepper, caraway, onions, and sometimes beer add flavor. Recipes vary between families, breweries, and festival tents.
The dish developed as a practical way to use leftover or overripe cheese, turning it into a spread rather than discarding it. It is now a classic Bavarian beer-garden and Oktoberfest snack, commonly served with a large pretzel, sliced radishes, onions, or chives.
A common mix-up is treating Obatzda as a single cheese variety. It is not: the name refers to a prepared cheese spread. Spellings such as Obazda and Obatzter also appear, especially in regional usage, but Obatzda is the standard form used in many English-language references.
