Nature's Flavours' Apple Flavoring System for Coffee & Tea is a unique recipe specially tailored to penetrate coffee beans, tea leaves, and any other dried herbs. Nature's Flavours' Flavoring Systems are water soluble, and 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 teaspoon of your favorite Nature's Flavours' 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 or Tea, we recommend you place these newly flavored beans or leaves within a sealable container like a mason jar, coffee can or zip-lock bag, then shake it vigorously to help disperse the flavor. After shaking, let the sealed container sit for 24 hours to allow the flavors to permeate the coffee or tea. Nature's Flavours 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 the name Flavor Oil was misleading. Nature's Flavours' Coffee and Tea Flavoring Systems are not set in an oil base and are not oil soluble. They are a direct evolution of our Flavor Extracts. As with our Flavor Extract, 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 within the first 24 hours. You will smell a little alcohol when first opening the sealed container, and any remaining alcohol will burn off immediately when brewing the coffee or tea. These flavors have no nutritional value as used in this application and are calorie, carb, and sugar free. You can enjoy your flavor knowing it is as healthy as it is tasty! Ingredients: Natural Vegetable Glycerin, Natural and Organic Flavors, and Natural Ethyl Alcohol.
