I recently made a smoked saison with habanero. I prepped 1 habanero and 2 Zavory peppers (a tame habanero hybrid from Burpee, same flavor and aroma but mild heat) by halving, deseeding and soaking in vodka. I put them in a giant SS tea ball and suspended them in my keg with dental floss. After about a week I removed them and repeated the process with another identical batch of peppers. It tastes great, lots of habanero flavor and smell with only moderate heat. The Zavorys initially trick you into thinking it's a lot hotter than it is.
