About 2-4 Weeks

Cannabutter, when stored properly in the refrigerator, typically lasts around 2 to 4 weeks. The quality degrades over time due to oxidation and the breakdown of cannabinoids. Maintaining a cool, dark place and using airtight containers are crucial for extending its shelf life. Proper storage is key to preserving flavor and potency.

Factors Affecting Shelf Life

• Temperature: Lower temperatures slow down degradation.
• Light: Exposure to light speeds up oxidation.
• Air Exposure: Oxygen causes rancidity.

Storage Methods Comparison

Method	Cost (Approx.)	Estimated Shelf Life
Airtight Glass Jar (Refrigerator)	$5 - $15	2-3 Weeks
Vacuum-Sealed Bag (Refrigerator)	$10 - $20 (for vacuum sealer)	3-4 Weeks
Freezer (Freezer Compartment)	$0 (if already have freezer)	2-6 Months

Tips for Extending Shelf Life

• Use Dark Glass Containers: Minimize light exposure.
• Minimize Air Exposure: Ensure a tight seal.
• Freeze Small Batches: This helps preserve potency and reduces waste.
• Avoid Repeated Opening: Each time you open the container, you introduce air.

Note: The potency of cannabutter will decrease over time. Regular testing is recommended to ensure desired effects. The color and smell can also change, indicating degradation.
