The tiny chili peppers of C. a. var. glabriusculum are red to orange-red, usually slightly ellipsoidal, and about in diameter. Some strains of tepin peppers are much closer to perfectly round when fresh. A dried tepin pepper appears quite round even if it was slightly ellipsoidal when fresh. Tepin peppers are very hot, in Scoville Heat Units (SHU) measuring between 465,000–1,629,000, or 325,000–2,469,000 depending on the capsaicinoid ⇨ SHU conversion method.
