This came up today and I thought it would be best to post my reply... Even if the new COA section is not live as of yet... It is coming I swear.
The shelf life of a flavor will vary widely. It is best to follow this guide. To find the exact date of manufacture, please refer to your lot number and our COA guide found on our website.
Super Concentrates have a shelf life of 12-18 months (60F° to 72F°) and up to 4 years if refrigerated. Never freeze flavors, this will cause some separation, and the flavor may "break" causing you never to get them to mix again.
Be sure to store all flavors in a cool, dark place away from sources of direct sunlight heat and flame; pigments in the flavor (from the natural extracts) tend to fade or discolor over time when exposed to sunlight. This fading is normal and is to be expected. Flavor bottles can explode in temperatures inside the container reach above 150F° from evaporation. For long-term storage, refrigerate, and then allowing the flavor to return to room temperature before opening or using the flavor.
