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.
Unopened Dried in Pantry2-4 years (for optimal quality)
Signs of Spoilage
Loss of potent aroma and flavor is the primary sign of degradation, not spoilage in a safety sense. Very rarely, if packaging is compromised, mold or pests could occur.
How to Check
Visually inspect the packaging for any damage. If the packaging is clear, check for any signs of moisture or clumping. Rub a small amount (if visible) between fingers to check for a strong aroma, though this is less practical for unopened. The main check for unopened is the 'best by' or 'packed on' date.
Storage Tips
Store in a cool, dark, dry place away from direct sunlight and heat sources. While safe for much longer, the quality (flavor and aroma) will diminish over time. The 'best by' date typically refers to peak quality, not food safety.
Opened Dried in Pantry6-12 months (ground), 1-2 years (whole leaves) for optimal quality
Signs of Spoilage
The most common 'spoilage' is a significant loss of aroma and flavor, making the spice ineffective. Other signs include: fading color, clumping or hardening due to moisture exposure, and in rare cases, mold growth or presence of pantry pests (small insects or webbing).
How to Check
-
Smell Test: Rub a small amount of the oregano between your fingers. It should release a strong, pungent, earthy, slightly citrusy aroma. If it smells faint, like dust, or has an 'off' smell, its quality has degraded.
-
Visual Inspection: Look at the color. Dried Mexican oregano should have a green-grey hue. If it's significantly faded, brown, or dull, its potency is likely low. Check for any signs of moisture (clumping), mold (fuzzy spots), or tiny insects/webbing.
-
Taste Test (Optional): If the smell and visual checks are acceptable, taste a tiny pinch. It should have a distinct, slightly bitter, earthy, and aromatic flavor. If it tastes bland or dusty, it's time to replace it.
Storage Tips
To maximize freshness, transfer opened dried oregano to an airtight container (dark glass jars are ideal) immediately after opening. Store in a cool, dark, dry place, away from heat sources (like above the stove) and humidity. Label with the date opened. Whole dried leaves retain potency longer than ground versions.
