Sauerkraut: What It Is and How to Eat It in Germany

What sauerkraut is: shredded cabbage and salt

Sauerkraut starts with white cabbage, called Weißkohl in German, sliced thin and mixed with salt. The salt draws water out of the cabbage, and lactic acid bacteria then ferment the sugars, which is what produces the sour flavor. The National Center for Home Food Preservation recommends firm heads of fresh cabbage for home fermentation, and it describes starting the process between 24 and 48 hours after harvest.

Serious Eats notes that a 2 percent salt ratio is the key starting point for a home batch. That simple combination of cabbage and salt is the whole foundation, and everything else is about time, temperature, and how the finished kraut is cooked or served. For a traveler, the useful takeaway is that sauerkraut is not a pickled cucumber-style quick pickle; it is a slow ferment.

How sauerkraut tastes and why the sourness varies

Expect a sharp, salty-sour flavor with a tender but slightly crisp texture. The sourness depends on how long the cabbage ferments and how the finished kraut is then cooked or served. Cooking changes it again, because sauerkraut braised with stock, wine, or a little fat turns rounder and less aggressive.

On a German menu, sauerkraut turns up in braised and slow-cooked dishes as well as on its own as a side. Ordering a small portion alongside a main is the simplest way to learn whether you prefer a bright, lightly cooked style or a mellower braised version.

What Germans serve with sauerkraut

The classic pairing is pork and sausage: Bratwurst, Schweinshaxe (roasted pork knuckle), and smoked pork all land on the plate with a mound of sauerkraut. Dumplings and boiled or mashed potatoes are the usual starch, and German sides such as Thüringer Klöße or plain Kartoffelpüree are common alongside. If you are building a plate, think of sauerkraut as the sharp counterweight to rich meat and buttery potatoes.

Sauerkraut also appears with spätzle, the egg noodles that show up across southern Germany. The tang of the kraut cuts through the richness of the noodles and browned butter, so the two work well in the same meal. For a broader look at the noodle itself, see Spätzle: Germany's Egg Noodles and How to Order Them.

At home, sauerkraut is often matched with German dumplings or with starchy potatoes, and the same logic applies in a Gasthaus. A plate of German dumplings plus kraut is a filling, inexpensive order when you want something warm and simple. If you want to understand the dumpling styles before you order, the German dumplings guide breaks them down.

Sauerkraut on a German menu: the words to look for

Look for Sauerkraut itself, then for compounds such as Krautwickel, which are cabbage rolls stuffed with meat and often served with kraut or a tomato sauce. Weinsauerkraut signals wine in the cooking liquid, and a dish labeled mit Sauerkraut simply comes with it on the side. Knowing those few words lets you spot the kraut dishes on a menu even when the rest of the description is unfamiliar.

If you want the sauerkraut experience in its plainest form, order a side of Sauerkraut with sausage or pork rather than a composed dish. That way you taste the kraut on its own and can judge whether you like the sour, fermented flavor before committing to a larger plate. For a wider view of how German meals are built, the German Side Dishes guide covers the usual lineup of potatoes, dumplings, and vegetables.

Sauerkraut straight from the barrel at a market

At German markets, sauerkraut is sometimes sold fresh from the barrel rather than only in shelf-stable jars. Kraut bought this way is generally raw and unpasteurized, so it tastes livelier and more layered than the jarred kind. Ask whether it is raw or already cooked before you buy, because that tells you how you will need to store and serve it.

Cooking barrel kraut gently with a little stock or wine softens the edge and makes it a better side for sausage and potatoes. If you prefer the bright, crunchy flavor, use it raw or barely warmed as a contrast to rich meat. Either way, a small amount goes far, so buy less than you think you need on a first visit.

Sauerkraut vs kimchi: fermentation and seasoning

Sauerkraut relies on salt and cabbage alone, which gives it a clean sour flavor rather than a spiced one. The fermentation is driven by lactic acid bacteria, which is what produces the tang.

That difference matters when you are matching kraut to a meal. Sauerkraut works as a sour, salty counterpoint to pork and potatoes, while kimchi brings heat and funk that push a dish in a different direction. Treat them as two separate traditions rather than as substitutes for each other.

Is sauerkraut healthy? What fermentation does

Fermentation turns shredded cabbage and salt into sauerkraut through lactic acid bacteria. The finished kraut is a salty vegetable side rather than a health treatment. If you plan to make your own batch, the National Center for Home Food Preservation covers safe home fermentation.

Beyond that, treat sauerkraut as a flavorful vegetable side rather than as a health treatment. The salt content can be high, especially in jarred versions, so it is not a food to eat in large amounts every day. If you are watching sodium, taste first and use it as a condiment-sized portion.

Why sauerkraut became a German staple

Sauerkraut is a practical way to preserve cabbage, which helps explain why it became a standard part of German home cooking. Cabbage is hardy and cheap, and the salt-fermentation process keeps it without refrigeration, so a household could put up a supply and eat from it through the cold months. That background helps explain why kraut so often sits alongside pork and potato dishes.

Today it is a familiar side rather than a survival food, but the pairing logic survives. Hearty, fatty meats and starchy dumplings still call for something sharp, and sauerkraut fills that role. Expect it most often in traditional Gasthäuser and on menus that lean on pork and potatoes.

How to buy and store sauerkraut in Germany

In German supermarkets, sauerkraut comes in glass jars and vacuum-sealed bags, and the refrigerated section may carry raw, unpasteurized versions. Check the label for the word roh if you want a raw product, and choose pasteurized jars if you prefer a milder, longer-lasting one. Serious Eats notes that a 2 percent salt ratio is the basis for a home batch, which is worth knowing if you plan to ferment your own.

Once opened, keep jarred sauerkraut in the refrigerator and use it within the period the label gives. If you buy raw kraut from a market barrel, ask the vendor how long it keeps and whether it should be refrigerated.

Which sauerkraut order fits your meal?

If you want the classic German plate, order sauerkraut with Bratwurst or Schweinshaxe and a dumpling or potatoes on the side. If you are curious about the kraut itself, ask for a side of Sauerkraut and compare the raw, sharp version with the softer braised style. Either way, it is a low-risk way to eat like a local without committing to a large, heavy dish.
