In MY opinion, the chocolate, red, and yellow are all fairly close in heat. (The yellow maybe trailing just a little.) The peach, purple, and white are REALLY new. Not a lot of people are growing them. From what I hear on the White Bhut's, they don't actually turn COMPLETELY white. I think one or two people might be growing the Peach Bhut this year. I would ask them on heat/taste. (I have seeds, and will try my hand at them NEXT year.) I also have a Purple Bhut growing, as does maybe one or two more people on here. I don't really think they are going to be that hot. They look more hab'ish to me. I'll be able to tell you soon. Also gonna send a few out for some people to test on video.
