Vegan Trentino Sauerkraut Braised with Apple and Juniper | Crauti Vegani alla Trentina
Crauti are the sauerkraut of the Italian Alps: white cabbage shredded, salted and left to ferment until it turns pale, tender and pleasantly sour, then braised slowly with onion, apple and mountain spices. In Trentino and in Alto Adige they are the classic winter side dish, served next to polenta, bread dumplings and potatoes. This recipe starts from the cabbage itself, with a precise home fermentation, and ends with a gentle braise in olive oil, white wine, juniper and caraway, so the crauti stay bright, aromatic and fully plant based. The method controls the salt, the temperature and the cooking time, which decide whether sauerkraut is crisp and lively or flat and mushy.

The Story
Fermented cabbage is one of the oldest ways to keep vegetables through the winter in Central Europe, and the high valleys of Trentino and Alto Adige share that culture with the Tyrol and Austria. For centuries the region was part of the Habsburg world, and its kitchen still shows it: canederli, strudel, goulash, and the Sauerkraut that in Italian became crauti. In the farmhouses, the cabbage harvested in autumn was shredded, salted and pressed into wooden barrels or stoneware crocks, and by the first snows it was ready to feed the family until spring.
The method is pure microbiology, discovered by practice long before it was understood. Salt draws water out of the cabbage and makes a brine, and in that brine the lactic acid bacteria that live naturally on the leaves multiply and turn the sugars of the cabbage into lactic acid. The acid preserves the cabbage, softens it and gives it its clean, sour taste. Nothing is added except salt and sometimes a few spices, and the result keeps for months in a cool cellar.
Traditionally, crauti in Trentino are braised with speck or other smoked cured fat, and served next to smoked meats, cured sausages and polenta, so the classic dish is not vegan. This version replaces the smoked fat with olive oil and a small amount of smoked paprika, keeps the onion, the juniper and the caraway of the mountain kitchen, and adds the apple that the valleys of Trentino and Alto Adige grow in abundance: Val di Non and the Alto Adige orchards are among the great apple districts of Europe, and both have protected apples, Mela Val di Non DOP and Südtiroler Apfel IGP.
Crauti remain a staple of the region's Christmas markets, of the mountain huts and of the family table, the sour counterpoint to rich winter food. This recipe follows the traditional process exactly, from the salting to the slow ferment and the braise, and adds precision where it matters at home: a measured 2 percent salt, a controlled temperature, a weighted surface and a short final cooking that keeps some bite.
Ingredients
Choose a heavy, tight head of white cabbage, with squeaky, pale leaves and no soft spots; late autumn cabbage is the sweetest and the juiciest, and it ferments best. Use pure sea salt without iodine or anti caking agents, which can slow the bacteria and cloud the brine. For the braise, pick firm, slightly tart apples and whole juniper berries that still smell of resin when crushed.
For the fermentation
White cabbage, 1 large head, about 4 1/2 lb (2 kg) after trimming
Fine sea salt, without iodine, 1 1/2 oz (40 g), exactly 2 percent of the cabbage weight
Caraway seeds, 1 tsp (2 g)
Juniper berries, 4, lightly crushed
Bay leaves, 2
For the braise
Home fermented crauti, drained, 2 lb (900 g)
Extra virgin olive oil, mild, 1/4 cup (60 ml)
Yellow onion, thinly sliced, 1 large, 8 oz (225 g)
Garlic, 1 clove, crushed
Tart apple, peeled, cored and grated, 1 large, 7 oz (200 g)
Juniper berries, 6, crushed
Caraway seeds, 1 tsp (2 g)
Bay leaf, 1
Smoked paprika, 1/2 tsp (1 g)
Dry white wine, such as Müller Thurgau or Pinot Bianco, 1/2 cup (120 ml)
Vegetable broth, unsalted, about 1 cup (240 ml)
Raw cane sugar, 1 tsp (4 g), optional
Freshly ground black pepper, to taste
For the finish
Extra virgin olive oil, 1 tbsp (15 ml)
Fresh chives or flat leaf parsley, finely chopped, 1 tbsp (3 g)
Tart apple, cut into fine matchsticks, 1/4 apple
Preparation
Step 1
Shred and weigh the cabbage. Remove the two outer leaves and keep one or two whole and clean. Quarter the cabbage, cut out the core and slice it very thinly, about 1/16 inch (2 mm), with a sharp knife or a mandoline. Weigh the shredded cabbage and calculate the salt at exactly 2 percent of its weight: 40 g for 2 kg. This ratio is the most important number of the recipe. Less salt lets undesirable microbes compete with the lactic bacteria and the cabbage softens; more salt slows fermentation and makes the crauti harsh.
Step 2
Salt and massage. Put the cabbage in a large bowl, sprinkle over the salt, the caraway, the crushed juniper and the bay leaves, and massage it firmly with clean hands for 8 to 10 minutes. The cabbage will shrink to about half its volume, turn translucent and release plenty of brine. The pressure of the hands breaks the cell walls and the salt pulls out the water by osmosis: the brine that forms is the protective liquid in which the fermentation takes place, so do not stop until it pools at the bottom of the bowl.
Step 3
Pack the jar and weight it. Pack the cabbage handful by handful into a clean 3 quart (3 l) glass jar or stoneware crock, pressing each layer with your fist or a wooden tamper to push out the air, until the brine rises above the cabbage. Pour in any brine left in the bowl. Leave at least 2 inches (5 cm) of space at the top. Cover the surface with the whole cabbage leaves and set a weight on top, a small jar filled with water or a fermentation weight, so that every shred stays under the brine. If after 24 hours the brine does not cover the cabbage, add a 2 percent brine, 1 tsp (6 g) of salt dissolved in 1 cup (240 ml) of water.
Step 4
Ferment and taste. Cover the jar loosely with its lid or a cloth, so the gas can escape, and set it on a plate in a place at 60 to 68°F (16 to 20°C), away from light. Bubbles appear within two or three days. Press the weight down daily for the first week and skim any white film from the surface. Start tasting after 3 weeks: the crauti are ready when they are pale, translucent, pleasantly sour and still crisp, usually after 3 to 4 weeks. At this temperature the lactic bacteria work steadily; warmer rooms make the cabbage sour faster but soft, colder ones slow everything down.
Step 5
Rinse and drain. When the crauti are ready, store what you do not use in the refrigerator in their brine. For the braise, take 2 lb (900 g), taste them, and if they are very sour, rinse them briefly in a colander under cold water, then squeeze them gently. Rinsing removes part of the acid and the salt on the surface; do it only if necessary, because it also washes away aroma. A balanced crauto needs no rinsing at all.
Step 6
Build the base. In a wide, heavy pan warm the olive oil over medium low heat with the onion and the garlic and cook for 10 to 12 minutes, until the onion is soft, sweet and lightly golden. Add the grated apple, the crushed juniper, the caraway, the bay leaf and the smoked paprika and cook for 2 minutes, stirring, until the spices are fragrant. Remove the garlic. The slow onion and the apple add sugars that soften the acidity of the crauti, while the fat carries the aromas of juniper and caraway, which dissolve better in oil than in water.
Step 7
Braise the crauti. Add the drained crauti and stir them into the base for 3 minutes. Pour in the white wine and let it bubble for 2 minutes, then add the broth until it reaches about halfway up. Cover and braise over low heat for 30 to 35 minutes, stirring occasionally, until the cabbage is tender but still has a slight bite and the liquid has mostly been absorbed. Taste: if they are too sour, add the sugar; season with black pepper. Uncover, cook for 3 more minutes to evaporate the excess liquid, then let the pan rest off the heat for 5 minutes.
Plating
Serve the crauti hot, around 165°F (74°C), in warm bowls or on warm plates next to the main course, heated to about 140°F (60°C). Lift them with a fork and let them fall loosely, so they form a light, airy mound rather than a compact block, and discard the bay leaf.
Finish with a thread of olive oil, a pinch of chives and a few matchsticks of raw apple, which add a fresh, crisp note against the soft braised cabbage. In Trentino they are served with polenta, potato dumplings or boiled potatoes; the guest eats them with a fork, together with the main dish, using them to cut its richness.
Professional Technique
The key ratio is the 2 percent salt by weight. It is the point at which lactic acid bacteria have the advantage over spoilage organisms while still working fast enough. Weigh the cabbage after trimming and shredding and weigh the salt on a precise scale: measuring by spoon is not accurate enough for fermentation.
The hidden variable is oxygen. Lactic fermentation needs an environment without air, and anything exposed above the brine can develop yeasts and molds. The whole leaves on the surface, the weight and the daily pressing during the first week keep the cabbage submerged. A thin white film on the brine is a harmless yeast to skim; fuzzy, colored mold means the batch must be discarded.
The doneness test is double. Fermentation is complete when the crauti are pale, evenly translucent and clearly sour, with no raw cabbage taste. After the braise they must be tender but not soft, with a slight resistance between the teeth, and their acidity must taste rounded rather than sharp.
Fermentation and Acidity Control
Temperature drives the speed and the character of the fermentation. Between 60 and 68°F (16 and 20°C), different bacteria take turns: the first ones produce gas and mild acids, the later ones more lactic acid, which gives the deep, clean sourness of a good crauto. Above 75°F (24°C) the process runs too fast, the cabbage softens and the flavor turns flat; below 55°F (13°C) it almost stops.
Acidity is also controlled in the pan. The onion, the apple and a small spoon of sugar, if needed, round the sourness; the wine adds its own fresh acidity and aroma; the broth dilutes and softens. Taste the crauti before the braise and adapt: a young, mild batch needs no sugar and no rinsing, a long fermented one may need both.
Cooking time decides the texture. The traditional braise can last more than an hour, until the cabbage almost melts. This version stops at 30 to 35 minutes, enough to soften the shreds and blend the flavors while keeping some crunch and a fresher taste. Long cooking also destroys much of the vitamin C of the cabbage.
Professional Mise en Place
Fermentation needs planning, not work: shred and salt the cabbage four weeks before you need it. The braise can be cooked up to two days ahead and reheated, which makes it ideal for service.

Chef Tips
Write the date and the salt weight on the jar. Fermentation is easier to repeat when you know exactly what you did, and after a few batches you will know how many weeks your kitchen needs.
Keep a cup of the brine. It is rich in lactic acid and flavor: a spoonful brightens a vegetable soup, a potato salad or a bean dish, and it can start a new batch of crauti faster.
For a more rustic, Alpine flavor, add a few whole crushed coriander seeds or a small piece of fresh horseradish to the jar. Both are traditional additions in the mountain kitchens and both work without changing the method.
Serve crauti with a vegan main of the same region: potato and buckwheat dumplings, polenta with mushrooms or roasted root vegetables. Their acidity balances the starch and makes the whole plate lighter.
Common Mistakes
Measuring the salt by eye. Too little salt invites spoilage and soft cabbage, too much stops the bacteria. Weigh the cabbage and use exactly 2 percent salt.
Using iodized salt. Iodine and anti caking agents can slow fermentation and cloud the brine. Use pure sea salt.
Leaving the cabbage above the brine. Exposed shreds dry out and grow mold. Keep everything submerged under leaves and a weight.
Sealing the jar tight. Fermentation produces carbon dioxide, and a sealed jar can build pressure. Cover it loosely or use an airlock lid.
Fermenting in a warm room. Above 75°F (24°C) the crauti turn soft and flat. Keep the jar in a cool place.
Rinsing every batch. Rinsing removes aroma along with acid. Rinse only very sour crauti, and briefly.
Overcooking. An hour of braising turns crauti into a gray mash. Stop when the shreds are tender but still have a slight bite.
Wine Pairing
Alto Adige Gewürztraminer DOC: The aromatic white of Alto Adige, with rose, lychee and spice and a full, round body. Its aromatic intensity meets the juniper and the caraway, and its weight softens the acidity of the cabbage. Serve it at about 50°F (10°C).
Trento DOC: The traditional method sparkling wine of Trentino, mainly from Chardonnay and Pinot Nero grown in the mountains. Its fine bubbles and lively acidity cleanse the palate, and its bready notes match the fermented character of the crauti. Serve it at about 46°F (8°C).
Alto Adige DOC Pinot Nero: A light, elegant red with red berry fruit, gentle tannins and fresh acidity. It accompanies the crauti when they are served with a hearty main, and its low tannin does not clash with the sourness. Serve it at about 59°F (15°C).
Teroldego Rotaliano DOC: The red of the Piana Rotaliana in Trentino, with dark cherry, violet and a fresh, juicy finish. Its fruit and acidity stand up to the smoked paprika and the onion, a natural regional match for a winter table. Serve it at about 61°F (16°C).
Storage & Reheating
Refrigerator: raw fermented crauti keep for 3 to 6 months in their brine in a closed jar, slowly becoming more sour; always use a clean fork to take them out. The braised crauti keep for 4 days in an airtight container, and their flavor improves on the second day. Freezer: braised crauti freeze well for up to 3 months, although they lose some crunch; raw crauti should not be frozen, because freezing kills much of their live bacteria and softens them.
Reheat the braised crauti in a covered pan over low heat with 2 to 3 tbsp (30 to 45 ml) of broth or water, stirring, for 6 to 8 minutes, until steaming throughout. In the microwave, cover and heat at 70 percent power for 2 minutes, stir, then 1 minute more. Finish with a thread of olive oil and fresh chives.
