The Fresno chile or Fresno chili pepper (/ ˈ f r ɛ z n oʊ / FREZ-noh) is a medium-sized cultivar of Capsicum annuum. It should not be confused with the Fresno Bell pepper. [ 1 ] It is often confused with the jalapeño pepper but has thinner walls, often has milder heat, and takes less time to mature.
A variety that produces capsaicin is colloquially known as a hot pepper or chili pepper. In British English , the sweet varieties are called "peppers" [ 12 ] and the hot varieties "chillies", [ 13 ] whereas in Australian English and Indian English , the name "capsicum" is commonly used for bell peppers exclusively and "chilli" is often used to ...
It is currently the most potent TRPV1 agonist known, [13] with ~500x higher binding affinity for TRPV1 than pure capsaicin, the active ingredient in hot chili peppers such as those produced by Capsicum annuum. It is 3 to 4 orders of magnitude more potent than capsaicin for effects on thermoregulation and neurogenic inflammation. [14]

The class of compounds causing pungency in plants such as chili peppers is called capsaicinoids, which display a linear correlation between concentration and Scoville scale, and may vary in content during ripening. [40] Capsaicin is the major capsaicinoid in chili peppers. [5]
The new peppers have been termed "super-hots". [6] Super-hots are classified as peppers registering over 1 million SHU. [7]In 2015, Bosland and his team, using fluorescence microscopy, found that super-hots not only have more capsaicin than other peppers, but also store their capsaicin differently.
The spicy capsaicin content of the chilis must have aroused the interest of the Portuguese, who for decades have been looking for easier sources for the then-rare black pepper of Asia (the piquant compound in which is piperine); one of the major motivations for the Columbian voyages was to discover a new route to Asia for direct trade in spices ...
Tabasco peppers start out green and ripen to orange and then red. It takes approximately 80 days after germination for them to fully mature. The tabasco plant can grow to 1.5 m (60 in) tall, with a cream or light yellow flower that will develop into upward-oriented fruits later in the growing season. [5]
