So far I've done a jalapeno mead and a habanero mead.
The jalapeno come out without any heat what so ever and had a very peppery taste. I myself am not too fond of it, but my friends really liked it.
I kicked it up a notch with the the habanero mead and tossed in the pepper with the seeds and pith. It is still in secondary, but I did take a little for a taster when I racked it last. It's very sweet, which is what I was aiming for with an og of 1.150, and has a very nice mouth warming feel to it that starts off slow and doesn't get too hot. But then again I like hot stuff so I could be murder so someone with a lesser tolerance.
