I advise against using store bought baking coconut. I recently did a cream ale with coconut, I toasted a 7 oz. package of shredded coconut to a medium brown and added it to the FV after fermentation was essentially complete. The beer turned out to be pretty tasty but there is a hint of a chemical aftertaste that I can't quite put my finger on, I'm almost certain though that it came from the coconut. In the future I think I'll either use fresh or at least something that doesn't have added sugar or preservatives. TIFWIW
