I bought them as white bhut joloka, and I thought they could be (they are lighter than my other peppers when green), until they started turning orange.
The spicyness, I cant really tell. The "tail" seems to not be really spicy, way way less than cayennes. And the top, seems to be more or less like cayennes.
Im ussing cayennes as a refference, because they are a common pepper arround here, donr know if its a good refference. And the spicyness data may not be really accurate, I may test them again later.
