Why Storage Matters
Proper storage is the difference between an infusion that stays potent for months and one that degrades in weeks. Active compounds break down when exposed to light, heat, air, and moisture. A well-stored infusion retains 90%+ of its potency over its expected shelf life.
Beyond potency, improper storage can lead to mold growth, rancid fat, and bacterial contamination — especially in dairy-based infusions like butter.
Shelf Life by Type
| Infusion Type | Room Temp | Refrigerated | Frozen |
|---|---|---|---|
| Infused Butter | Not recommended | 2-3 weeks | 6 months |
| Coconut Oil | 2-3 months | 6+ months | 1+ year |
| MCT Oil | 6+ months | 1+ year | 2+ years |
| Olive Oil | Not recommended | 1-2 months | 6 months |
| Alcohol Tincture | Indefinite* | Indefinite* | N/A (don't freeze) |
| Glycerin Tincture | 6 months | 1-2 years | N/A |
| Gummies | 1-2 weeks | 2-3 months | 6+ months |
* Alcohol tinctures at 60%+ ABV are self-preserving and do not require refrigeration, though cool dark storage is still preferred.
The Four Enemies of Potency
Active compounds degrade through four main mechanisms. Minimizing exposure to all four is the key to long-lasting infusions.
- Light — UV radiation breaks down active compounds. Use opaque or amber containers.
- Heat — temperatures above 70°F (21°C) accelerate degradation. Refrigerate when possible.
- Air — oxygen causes oxidation. Use airtight containers with minimal headspace.
- Moisture — water promotes mold and bacterial growth. Keep containers dry and sealed.
Best Practices
- 1Use airtight glass containers (mason jars work perfectly) — avoid plastic which can absorb compounds
- 2Store in a cool, dark location — a refrigerator is ideal for most infusions
- 3Minimize headspace in containers — less air means less oxidation
- 4Use opaque or amber glass to block light degradation
- 5Label everything immediately (see Labeling Checklist below)
- 6Keep a consistent temperature — avoid frequent warming and cooling cycles
- 7For butter and oil, ensure the infusion is fully cooled before sealing the container
Freezer Tips
Freezing is the best long-term storage method for fat-based infusions. The cold temperature virtually halts all degradation processes.
- Portion into single-use amounts before freezing (silicone molds work great for butter/oil)
- Wrap tightly in plastic wrap, then place in a freezer bag with air squeezed out
- Label with date, type, and estimated potency per portion
- Thaw in the refrigerator, not at room temperature — prevents condensation
- Once thawed, use within the refrigerated shelf life — do not re-freeze
- Frozen gummies may change texture slightly — let them come to room temperature before consuming
Silicone ice cube trays are perfect for portioning infused butter or oil before freezing. Each cube is roughly 1-2 tablespoons — a convenient pre-measured dose for cooking.
Labeling Checklist
Every container of infused product should be clearly labeled. This is essential for safety, especially in shared households.
- Product name (e.g., "Infused Coconut Oil")
- Date made
- Estimated potency per portion (mg)
- Portion size (e.g., "1 tablespoon = ~10mg")
- Total number of portions
- Source material used and concentration
- Carrier type and amount
- "INFUSED — KEEP AWAY FROM CHILDREN" warning
When to Discard
Any mold growth (fuzzy spots, discoloration), sour or rancid smell, slimy texture, or any off-putting change in appearance. When in doubt, throw it out — a wasted batch is better than a health risk.
- Butter: discard if sour smell, mold, or off-white/yellow discoloration
- Oils: discard if rancid smell, cloudiness, or visible mold
- Tinctures: rarely spoil, but discard if cloudy or has visible particles
- Gummies: discard if sticky, slimy, or show mold
- Any infusion past its expected shelf life should be discarded
