Nature's Flavors' Blueberry Flavoring System for Coffee & Tea is a unique recipe specially tailored to penetrate coffee beans, tea leaves, and any other dried herbs. Nature's Flavors' Flavoring Systems are water soluble, and will also mix well with vegetable glycerin and propylene glycol. All of our Coffee and Tea Flavors are Kosher, Vegan, Gluten-free, and contain no Allergens. To add Flavor to your own Coffee Beans, Tea Leaves, and other dried Herbs, simply take one pound of roasted coffee beans and one-half of a teaspoon of your favorite Nature's Flavors' Coffee and Tea Flavoring System and sprinkle it over your beans. For the most even distribution we use a sprayer. Once you have distributed your Flavor over your Coffee, we recommend that you place these newly flavored beans within a seal-able container like a mason jar, old coffee can, or a zip-lock bag, then shake it up to help spread the flavor out, and then let the sealed container sit for 24 hours to allow the flavors to permeate the coffee or tea. Nature's Flavors has recently renamed our Flavor Oils for Coffee and Tea, or Coffee and Tea Flavoring Oils, to Flavoring Systems for Coffee and Tea, or Coffee and Tea Flavoring Systems, due to the fact that the name Flavor Oil was misleading. Nature's Flavors' Coffee and Tea Flavoring Systems are not set in an oil base, and are not oil soluble. They are a direct evolution from our Flavor Extracts. Like our Flavor Extracts there is a small amount of alcohol added to help the flavors permeate the coffee beans or tea leaves. It will evaporate out of the beans or herbs usually with in the first 24 hours. You will smell a little alcohol when you first open the sealed container, any remaining alcohol will burn off immediately when you brew the coffee or tea. These flavors have no nutritional value as used in this application are calorie, carb, and sugar free. There is no fat. Enjoy. Ingredients: Natural Vegetable Glycerin, Natural and Organic Flavors, and Natural Ethyl Alcohol.
