- Bell Pepper: A sweet, mild pepper available in various colors, used in salads, stir-fries, and stuffed dishes.
- Serrano: A small, hot pepper often used in salsas and hot sauces.
- Poblano: A mild pepper often roasted and stuffed, known as chile relleno.
Capsicum frutescens: Home to the Tabasco Pepper
Capsicum frutescens is a species of chili peppers known for its upright growth habit and small, fiery fruits. The most famous member of this species is the Tabasco pepper, the key ingredient in Tabasco sauce. Capsicum frutescens peppers are generally hotter than many Capsicum annuum varieties and possess a distinct fruity flavor.
Key characteristics of Capsicum frutescens include:
- Upright growth habit
- Small, conical fruits that typically grow upwards
- High heat levels
- Fruity flavor profile
Examples of popular Capsicum frutescens cultivars:
- Tabasco: The quintessential ingredient in Tabasco sauce, known for its intense heat and distinctive flavor.
- Malagueta: A popular pepper in Brazilian cuisine, used in sauces, stews, and marinades.
- Piri Piri: Also known as African Bird’s Eye chili, used extensively in African and Portuguese cuisine.
Capsicum chinense: The Hottest Chili Pepper Species
Capsicum chinense is renowned as the species of chili peppers that produces some of the hottest peppers in the world. This species includes the infamous habanero, scotch bonnet, ghost pepper (Bhut Jolokia), and Carolina Reaper. While these peppers are known for their extreme heat, they also possess complex and fruity flavor profiles.
Key characteristics of Capsicum chinense include:
- Extremely high heat levels, often exceeding 1,000,000 SHU
- Fruity and floral aroma
- Wrinkled or bumpy skin
- Long growing season
Examples of popular Capsicum chinense cultivars:
- Habanero: A popular hot pepper with a distinctive fruity flavor, commonly used in Caribbean and Mexican cuisine.
- Scotch Bonnet: A Caribbean pepper similar to the habanero, known for its intense heat and sweet flavor.
- Ghost Pepper (Bhut Jolokia): Once considered the hottest pepper in the world, with extreme heat and a smoky flavor.
- Carolina Reaper: Currently the hottest pepper in the world, with scorching heat and a fruity, slightly sweet flavor.
Capsicum baccatum: The Aji Peppers
Capsicum baccatum is a species of chili peppers primarily found in South America, characterized by its distinctive fruity flavor and moderate heat. This species includes the Aji peppers, which are staples in Peruvian and Bolivian cuisine. Capsicum baccatum peppers are often used in sauces, stews, and as a condiment.
Key characteristics of Capsicum baccatum include:
- Fruity and citrusy flavor
- Moderate heat levels
- Long, slender fruits
- Adaptability to cooler climates
Examples of popular Capsicum baccatum cultivars:
- Aji Amarillo: A popular Peruvian pepper with a fruity flavor and moderate heat, used in many traditional dishes.
- Aji Limon: A pepper with a distinct citrusy flavor and moderate heat, often used in ceviche and other seafood dishes.
- Bishop’s Crown: A decorative pepper with a mild heat and a unique bell-like shape.
Capsicum pubescens: The Rocoto Peppers
Capsicum pubescens is a unique species of chili peppers characterized by its hairy leaves and black seeds. This species includes the Rocoto peppers, which are native to the Andes region of South America. Rocoto peppers are known for their thick flesh, juicy texture, and moderate heat. They are often used in stews, sauces, and stuffed dishes.
Key characteristics of Capsicum pubescens include:
- Hairy leaves
- Black seeds
- Thick flesh
- Moderate heat levels
- Adaptability to cooler, high-altitude climates
Examples of popular Capsicum pubescens cultivars:
- Rocoto: A popular Andean pepper with thick flesh and a juicy texture, often used in stews and stuffed dishes.
- Manzano: A similar pepper to the Rocoto, also native to the Andes region.
Beyond the Five: Wild Chili Pepper Species
While the five domesticated species of chili peppers form the basis of most commercially available peppers, numerous wild species exist in the Americas. These wild species often possess unique genetic traits that could be valuable for breeding and improving cultivated varieties. They also play an important role in the ecosystem, serving as a food source for birds and other animals.
Some notable wild Capsicum species include:
- Capsicum chacoense
- Capsicum galapagoense
- Capsicum cardenasii
The Scoville Scale: Measuring the Heat of Chili Peppers
The Scoville scale, developed by pharmacist Wilbur Scoville in 1912, is a system for measuring the pungency (spiciness or “heat”) of chili peppers. The scale is based on the concentration of capsaicinoids, the chemical compounds responsible for the burning sensation experienced when consuming chili peppers. The heat level is measured in Scoville Heat Units (SHU). [See also: Understanding the Scoville Scale].
Understanding the Scoville scale helps consumers and chefs choose the right chili pepper species and varieties for their desired level of heat. Bell peppers have a SHU of 0, while the Carolina Reaper can reach over 2,200,000 SHU.
Cultivating Chili Peppers: A Guide for Gardeners
Growing your own chili peppers can be a rewarding experience. Different species of chili peppers have varying requirements for sunlight, water, and soil. Generally, chili peppers thrive in warm climates with well-drained soil and plenty of sunshine. Starting seeds indoors several weeks before the last frost is recommended in cooler climates.
