My current mead has them in it, as well as a couple of other fruits. Pineapple can be tasted, and I probably didn't add enough bananna. I would suggest planning on racking onto them in the secondary (as well) to get maximum fruit flavor--I didn't and can barely taste the fruits. Hopefully they'll come out with age.

While I didn't have too much problem with foam--but I still second this, lol.
