Every time I want to impart flavor for an apfelwein or any kind of cider or wine, I usually take part of the base liquid (apple juice, water, etc.) and then make a tea with the flavoring. For example, I take 1/2 gallon of apple juice in a non-reactive pot and place broken cinnamon sticks and crushed nutmeg berries in a piece of cheesecloth. I then tie the sachet and add to the juice, then bring to a boil. After boiling for about 5 minutes, remove from the heat and let steep for 1-3 hours, covered. After that, add it to the must and you should get a really good flavor from it. Of course that is my 2 cents worth, but it works for me
