About

RB003 is a superhot Capsicum chinense variety bred by Australian grower Ross Barber. It is a cross between a yellow Carolina Reaper and a 7 Pot Brainstrain. The pods are gnarly, bumpy, and scorpion-like with prominent tails, ripening from lime green to a deep dark red. It offers brutal heat combined with bright citrus, fruity, and floral flavors that make it excellent for hot sauces.
