Mix 4-6 ounces of our Chaga grounds with one liter of 80 or 100 proof vodka or other alcohol (use flavored alcohol for different tincture flavors). Let sit 3-4 weeks, shaking daily. Filter the liquid from the grounds. Use liquid as desired. Either dehydrate, or freeze, grounds for future use or immediately begin a soak and cook in hot water to make a water extract to add to the alcohol tincture to make a double extract.
