The chocolate bhutlah is across in between Douglah and a bhut jolokia (ghost pepper). to Personally for me when super hots reach a certain level it's hard to tell which is hotter. Especially without testing. But I will personally say this one is a scorcher. When you cut one open you can see the capsaicin oil. That oil is bringing the heat to the pepper.
Medium to high yields and very large peppers.
