Safety first: This guide provides general information. When in doubt, throw it out! Trust your senses and err on the side of caution. If something smells, looks, or tastes off, don't consume it.
opened refrigeratorFor best quality, 1-3 months. Can remain safe for consumption up to 6 months, but flavor and pungency will significantly diminish over time.
Signs of Spoilage
Visible mold growth (rare but possible), significant discoloration (e.g., turning brown, grey, or dull), a sour, musty, or 'off' odor, an unusually watery or hardened texture, or excessive liquid separation that doesn't mix back in easily.
How to Check
Visual Inspection: Look closely for any mold spots, changes in color, or unusual consistency. Check for excessive pooling of liquid. Smell Test: Open the container and take a gentle sniff. It should have a sharp, pungent, characteristic wasabi/horseradish aroma. If it smells weak, sour, fermented, or otherwise unpleasant, it's best to discard. Texture Test: If visual and smell tests are fine, observe its consistency. It should be a smooth paste. If it's very dry, crumbly, or excessively watery and doesn't mix, quality is compromised. Avoid tasting if other signs are present.
Storage Tips
Always reseal the tube or jar tightly immediately after use to minimize air exposure. Use a clean, dry utensil each time to prevent introducing moisture or contaminants. Store in the main body of the refrigerator, not the door, for more consistent temperature.
