Folks, I don't know how many varieties of habanero there are. The ones I know about begin green then mature to either red (as in red savina) or orange (the scotch bonnet and other varieties). For heat: 1) The green is immature and heat minimal (for habs). 2) The yellow/orange varieties are hot. 3) The red a bit hotter. These rankings are of course my subjective opinions. Now, I have found the red savina a bit smaller, rounder, less wrinkled, and not quite as pointed on the bottom. The flesh is a bit thicker, but not so thick that it is more time consuming to dry them (like jalapenos). That's my two cents worth. Brandon Nuttall in digest land bnuttall@kih.net
