A shallow cream ceramic bowl of pale white-to-light-yellow, finely cut raw Choucroute d’Alsace, the fermented cabbage product.

What it is

Choucroute d’Alsace is cabbage cut into long, fine strips and fermented with salt. The strips are white to light yellow, slightly crunchy when the product is eaten raw and firm when it has been cooked, with a mildly tangy taste. The name comes from the Alsatian Sürkrüt, sour cabbage.

The protected name covers the vegetable, not the plate. The specification recognises choucroute crue, served raw after fermentation, and choucroute cuite, cooked after fermentation. Choucroute garnie is a separate thing: the dish of choucroute served with meat and charcuterie. Cooking changes the presentation of the cabbage; it does not make a different ferment.

History and protection

INAO places the product in the practice of keeping cabbage through Alsace's hard winters, when fermenting it in quantity was a way to preserve it. A 2018 published application for the protected indication cites Jérôme Bock's 1539 herb book as an early written reference to salted cabbage under the name Sauerkappes. That is an attestation, not a date of invention and not proof of an unbroken practice.

The legal steps are separate. France homologated the national specification by decree on 8 October 2012, and the version of the document consulted is dated 18 April 2013. The European Union registered Choucroute d’Alsace as a protected geographical indication in 2018.

How the fermentation works

Salt draws liquid out of the cut cabbage. The lactic-acid bacteria already present on the cabbage use its sugars and produce lactic acid, which sours the cabbage and helps keep it. The specification describes salted, cut cabbage placed in fermentation vats and says no starter culture is added to begin the fermentation.

The specification sets product requirements, not a household formula. The sources reviewed give no salting rate, duration, temperature or endpoint, so none is stated here.

Uses and limits of the evidence

The fermented cabbage is eaten raw or cooked, and choucroute garnie is the best-known cooked serving, with meat and charcuterie. The specification also permits other cooked presentations.

These definitions describe the protected Alsatian product. They should not be applied automatically to every unprotected regional use of the word choucroute. The 1539 reference is known only through the published application; the book itself was not examined.

Method

Risks and precautions · Standard risk
Unvalidated household method

The sources describe the protected product's specification, not a household process with a salting rate, endpoint or storage limits.

Hazard source

Use a separately validated cabbage-fermentation method for quantities, salt rate and storage; appearance, smell and bubbling do not establish safety.

Control source

The sources reviewed give no household quantities, salt rate, endpoint or storage guidance.

  1. Cut the cabbage into long, fine strips.
  2. Salt the cut cabbage.
  3. Place the salted cabbage in fermentation vats. No starter culture is added; the cabbage's own lactic-acid bacteria carry out the fermentation.
  4. Let natural lactic fermentation run in the vats until the cabbage has turned sour.
  5. Sell or eat it raw as choucroute crue, or cook it after fermentation as choucroute cuite.
