Overview

Key Details

  • Refrigerator: 4-6 months (opened)
  • Freezer: Not recommended (kills probiotics)
  • Pantry/Counter: 12-18 months (unopened, pasteurized)
  • Category: Condiments

Why This Matters

  • Spoilage sign: Pink or brownish discoloration on top layer
  • Spoilage sign: Fuzzy mold on surface
  • Spoilage sign: Extremely soft or mushy texture
  • Spoilage sign: Off or putrid smell (tangy is normal)

How To

  1. 1Keep sauerkraut submerged under brine — exposed portions spoil first
  2. 2Unpasteurized sauerkraut contains live probiotics — keep refrigerated
  3. 3Top layer may darken — scrape off and the rest is fine
  4. 4Use clean utensils each time — introducing bacteria shortens shelf life
  5. 5Pasteurized (shelf-stable) sauerkraut has no live probiotics but lasts longer
