Buying spices from the bulk section of your grocery store will get you plenty of Chai flavors . You will definitely want cinnamon , cardamom , and ginger best fresh , but it keeps a while . Other good flavors are clove , nutmeg , black pepper , and even a touch of mint . I have made concentrates by boiling the crushed spices for an extended period of time , but if you wanted to make a bulk concentrate to save over a long period of time I don ' t think that method will work well . This is how I make it for immediate consumption . I ' ve never considered using alcohol to infuse the flavors , it may just work though . If it doesn ' t work for your protein shakes , I bet it would make a hell of a cocktail . <| sep |> does it work on version 9 . 8 ?
