Just did a google search for the drink .. Looks like a lot of them do use apple so I'm sure that's where the name came from. It would probably be a good addition ... a mix of FA Fuji and Stark Apple at 1%.
I think I will add it to the recipe.
The great thing about that site is you can search for mixes using just about any flavor you want.
Say you want to find recipes for strawberries. Click on the S and then scroll down to Strawberries. You'll find 95 recipes that use it. Its a great way to find flavor combinations that go together for recipe ideas.
