Germany didn't actually invent sauerkraut. But step into a German supermarket, and you'll find entire aisles of cabbage fermented in dry Riesling, hard apple cider, and even sparkling wine.
The technique actually originated in China over 2,000 years ago. It was brought to Eastern Europe by the Tartars, eventually making its way into Germanic regions. Because cabbage grew exceptionally well in the cold, temperate climates of Northern Europe, and because fermentation prevented scurvy during brutal winters, Germans enthusiastically adopted it.
While the core technique is ancient, the massive supermarket variety exists today because Germany is a fiercely regional food culture. The products on the shelf are not just competing brands, but completely different recipes.
Standard sauerkraut is just cabbage and salt. But those wine-infused varieties from the supermarket aisle originate in the Rhineland, where cabbage is fermented with white wine to create Weinkraut, giving it a lighter, fruity acidity. Sektkraut uses local sparkling wine, while around Frankfurt, the cabbage is prepared with Apfelwein (hard apple cider).
The spices vary by state. A Bavarian brand will almost always include Kümmel (caraway seeds) and is designed to be cooked down with pork fat. In Swabia, sauerkraut is often infused with apples, making it sweeter and milder to balance out hearty local dishes. Jars are often pre-mixed with juniper berries, bay leaves, or cloves, each calibrated to a specific traditional meal.
The variety also extends to biology and texture. In the refrigerated section, you can buy Frisches Sauerkraut in a plastic bag. This is raw, unpasteurized, and full of live lactic-acid bacteria. It is sour, crunchy, and requires an hour of braising. On the dry shelves, jars and cans are pasteurized and pre-cooked. Brands like Hengstenberg’s Mildessa are heavily cooked down to be soft and mild, requiring only three minutes in a microwave. Some traditionalists prefer a thick, hearty shred that holds its crunch when braised with a pork shoulder, while other brands offer an ultra-fine, almost hair-like shred that practically melts.
To a German cook, sauerkraut is a foundational ingredient rather than a simple condiment. The vast supermarket selection exists because a rich Bavarian pork roast requires a completely different cabbage profile than a delicate Thuringian sausage.
