Peppers are classified in types according to their size, sweetness and bitterness. Almost all the varieties cultivated in Europe belong to the species Capsicum annuum. Other species, most of them hot peppers, such as the famous Jalapeños Chili peppers, etc. are mainly cultivated in America.
There are different species that defer from one another mainly in the number and colour of the flowers of each inflorescence, shape and type of fruit, length of the vegetative cycle, etc.; although there are others and multiple types of pepper, both sweet as hot.
We make the distinction of varieties in large fruit, smaller fruit and very narrow and lengthy fruit:
- Large fruit: Infantes, with fruits weighing more than 250g, "Grande de Plaza’ or "Morrón de Plaza’ with heart shape, "Morro de Vaca’ very extended in Spain and also known as "Morrón Dulce’ or "De Fresno’, "Largo de Reus" in the Mediterranean coast, known in France as " Dulce de España’, "Najerano’ only in La Rioja, "Amarillo de Mallorca’ with matured thick yellow fruit.
- Smaller fruits: "Cistal" and "Marconi’ (typical from the País Vasco to Gernika) used to fry when green, pepper "De Padrón" , and " De Arnoia’ (typical from Galicia) used in the Galician ‘empanada’ (a kind of pasty).
- Very narrow and lengthy fruit: ‘Guindilla Amarilla’ from Ibarra, "Guindilla de San Sebastián", etc. that are eaten both fresh as pickled; other varieties of hot peppers are used to preserve and some ivory-coloured varieties for pickling in brine.
Peppers can also be classified according to their sweet or hot taste:
- Sweet: They are eaten raw, intact or chopped for salads or cooking, when they are green or purple, or already mature. The most known varieties are for example the Valencian Pepper, Morrón, Hocico o Bonete, Temprano de Valencia, Cuadrado de America, Del Pico, De Cristal, Amarillo y Verde de Mallorca, Najerano, Largo de Reus or Grande de Torroella, Morro de Vaca and Cornicabra, among others.
- Hot: They contain an alkaloid causing the bitter or hot taste, and it is called capsaicin. They are consumed raw or pickled and as garnish, the paprika. The mostly known varieties are for instance the type guindilla (hot pepper), the Cornezuelo pepper, Cerecilla or Indias, Rojo de Cayena, Picante Amarillo, Rojo Largo, De Padrón, Ñora, etc.
Along with Spain, Italy is also an important country of fresh peppers production. In Italy, the type " Lamuyo largo’ is cultivated in greenhouses in Sicily (harvests between March and July) and to the south of Rome and in the Tirrenean Sea they also produce the type " Italiano’ and "California amarillo (June-September).
In Asia, Turkey is the country that produces more peppers after China; it has two great producing areas, both in the peninsule of Anatolia and the Mediterranean Sea. In Antalya, the varieties cultivated in greenhouses are Turkish types, of yellowish green colour (October-March). In Izmir, zone next to Istambul those of Italian type are cultivated (June-September).
In North America, by its geographic amplitude, the pepper production extends during good part of the year. To that supply the import of red square pepper of Holland is added (April and October). Also there is certain production under conservatory in the U.S.A. and Mexico, but still enough it is reduced. In the U.S.A. the main cultivated types of pepper are Bell or Californian Wonder, Pimiento or Morrón de Conserva , Roumanian Sweet, Anaheim, Wide , Caloro, Jalapeño , Cayena , Sweet Cherry, Serrano and Tabasco in greater proportion. In Mexico the main types of peppers or " chillies" are Jalapeño , Serrano , Ancho , Mulato, Pasilla , Bravo, Piquín , Chiltepín, Various (dry), Habanero , Manzano , Bell and others.
