If your CBD tincture has become discolored over time, it may be time for an upgrade. The hue of CBD oil depends on several factors such as its type of hemp extract used and extraction method – darker oils have undergone less processing; lighter refined oils tend to be milder in flavour.
CBD vape oils often turn darker when exposed to heat and lengthy shelf times; this doesn’t indicate spoilage as most contain MCT or olive oil combined with CBD extracts that remain very stable over time. To preserve freshness, store it in a cool, dark location in order to extend its shelf life and ensure maximum freshness.
Oxidation can also play a part in turning your CBD tincture brown; this natural process occurs when any oil is exposed to oxygen and heat for extended periods, like leaving cut apple exposed after cutting it. With time, oxidation causes your CBD extract’s color to change from its initial transparent state into shades of pink or brown.
Your CBD tincture’s color change could be the result of overexposure to heat and sunlight. To extend its shelf life and preserve freshness, store your CBD tincture in an area with low levels of heat, darkness, and humidity.
