The Carribean Red Habanero has scored up to an incredible 475, 000 Scoville Units on the hotness scale, which is rivaled only by the legendary Red Savina Habanero (525, 000). Of course, your mileage may vary according to the season and record-high hotness scores are always exceptional. But you can be sure that the Caribbean Red packs a powerful wallop by any measure -- that is, about twice as hot as an ordinary Habanero. Peppers grow to about 1" in diameter and 1-1/2" in length. Definitely an amazing, unforgettable experience.
