Sauerkraut, a beloved fermented cabbage dish, offers a tangy, probiotic-rich addition to many meals. Proper storage is key to maintaining its crisp texture and vibrant flavor, ensuring you can enjoy this versatile food for longer. Understanding how to store sauerkraut correctly helps preserve its beneficial qualities and prevents premature spoilage.
Storage Time
Unopened commercial sauerkraut can last 12–18 months in the pantry. Once opened or for homemade batches, store in the refrigerator for 1–2 weeks (commercial) or 2–4 weeks (homemade). Sauerkraut can also be frozen for 6–8 months.
Temperature
Keep opened or homemade sauerkraut refrigerated at a consistent temperature between 0–4°C (32–40°F) to inhibit bacterial growth and maintain freshness. Unopened commercial sauerkraut should be stored in a cool, dark pantry, ideally below 20°C (68°F).
Freezing
Yes, sauerkraut freezes remarkably well. To freeze, drain any excess liquid if desired, then pack the sauerkraut into freezer-safe airtight containers or heavy-duty freezer bags, leaving about an inch of headspace to allow for expansion. Freezing may slightly soften the texture, but the tangy flavor will remain intact. Thaw frozen sauerkraut slowly in the refrigerator overnight before use, or add directly to cooked dishes.
Signs of Spoilage
- Visible Mold Growth: Any fuzzy, discolored spots (green, black, pink, or white) on the surface or within the sauerkraut indicate spoilage and the entire batch should be discarded.
- Off-Putting Odor: While sauerkraut has a distinct tangy aroma, a strong yeasty, putrid, rancid, or unusually sour smell that is not its typical fermented scent is a clear sign it has gone bad.
- Slimy or Mushy Texture: Fresh sauerkraut should be crisp and firm. If it becomes slimy, overly soft, or mushy, it has likely spoiled and should not be consumed.
- Significant Color Change: While slight darkening can occur, unusual pink, orange, or very dark brown discoloration beyond its typical pale yellow-green hue can signal spoilage.
