What is the Scoville Scale?

The Scoville Scale is a measurement system used to determine the heat level or spiciness of peppers. It was developed by pharmacist Wilbur Scoville in 1912 and has since become the go-to method for rating pepper heat.

The Science Behind the Scoville Scale

Capsaicin In Hot Peppers

Capsaicin is a natural chemical compound found in chili peppers belonging to various Capsicum species, such as Capsicum frutescens, Capsicum chinense, Capsicum baccatum, Capsicum rhomboideum, Capsicum eximium, and Capsicum pubescens. This compound gives them their characteristic spiciness.

The amount of capsaicin pungency in a hot pepper determines its heat level and Scoville Heat Unit (SHU).

Capsaicin concentration varies among different pepper varieties within these Capsicum species and is responsible for the burning sensation experienced when consuming spicy peppers.

Factors Affecting Pepper Heat

Several factors influence the heat of a pepper, including growing conditions, hours of sunlight, moisture, soil chemistry, type and amount of fertilizer used. These factors can affect the concentration of capsaicin in the pepper, which in turn affects its heat level.

Growing Conditions

Pepper plants require warm and humid conditions to grow. The ideal temperature range for pepper plants is between 60°F and 90°F. The plants require well-drained soil and regular watering to thrive.

Hours of Sunlight

Pepper plants require at least six hours of sunlight per day to produce fruit. If the plants receive less than six hours of sunlight, the fruit may not develop properly, resulting in a lower concentration of capsaicin.

Moisture

Pepper plants require regular watering to produce fruit. However, overwatering can result in a lower concentration of capsaicin in the fruit. Additionally, high humidity can also affect the concentration of capsaicin.

Soil Chemistry

The type of soil in which the pepper plants are grown can affect the concentration of capsaicin. For example, sandy soil may produce peppers with a milder flavor, while clay soil may produce peppers with a stronger flavor.

Type and Amount of Fertilizer Used

The type and amount of fertilizer used can affect the concentration of capsaicin in the pepper. Fertilizers high in nitrogen can result in a higher concentration of capsaicin, while fertilizers high in phosphorus can result in a lower concentration of capsaicin.

Measuring Pepper Heat: The Scoville Organoleptic Test

Using the Scoville Heat Units (SHUs), the scale is based on the Scoville Organoleptic Test, which relies on human taste testers to determine the heat level of a pepper or hot sauce.

The extract of chili pepper is diluted in sugar water until its heat is no longer detectable by the testers. The degree of dilution corresponds to the pepper's SHU rating.

Modern Methods for Measuring Pepper Heat: HPLC

Although the Scoville Organoleptic Test remains popular, modern methods like High-Performance Liquid Chromatography (HPLC) offer a more accurate and objective measurement of capsaicin concentration in peppers.

Despite its limitations, the Scoville Scale continues to be the most easily understood and widely used method for describing pepper heat.

Peppers from Mildest to Hottest as Measured on the Scoville Heat Scale

The Scoville Scale rates a wide variety of peppers and hot sauces based on their heat levels.

Some popular peppers, arranged from mildest to hottest as measured using the scoville rating, the higher the capsaicinoids number, the hotter:

Bell Pepper (0 SHU)
Poblano Pepper (1,000-2,000 SHU)
Jalapeño (2,500-8,000 scoville units)
Serrano Pepper (10,000-23,000 SHU)
Cayenne Pepper (30,000-50,000 SHU)
Habanero Peppers (100,000-350,000 SHU)
Ghost Pepper (Bhut Jolokia) (855,000-1,041,427 SHU)
Trinidad Moruga Scorpion (1.2 2 million scoville )
Carolina Reaper (1.5 2.2 million SHU) (our hottest chili pepper)

Dried Peppers

Dried peppers are an essential ingredient in various cuisines worldwide, providing a concentrated and robust flavor.

The heat of dried peppers depends on various factors, including the conditions they were grown in and the drying process itself. Example: jalapeño peppers smoked, which become dried, are chipotles.

Tame the Heat: Neutralizing Capsaicin

If you've accidentally gone overboard with the heat in a dish, don't fret! There are ways to neutralize capsaicin and bring the heat level down a notch.

Dairy products, such as milk, yogurt, or sour cream, can help counteract the spiciness due to their fat and protein content. Additionally, serving a spicy dish with a side of rice, bread, or other starchy foods can help absorb some of the heat.

Safety First: Handling and Preparing Chili Peppers

When working with hot peppers, it's crucial to take safety precautions. Capsaicin can cause irritation or burning sensations when it comes into contact with skin, eyes, or mucous membranes.

To avoid mishaps, wear gloves when handling and chopping chili peppers, and avoid touching your face, especially your eyes.

Conclusion: Scoville Heat Units Scale

Understanding the science behind the pure capsaicin Scoville Scale and pepper heat allows us to appreciate better the diversity of flavors and heat levels that peppers offer.

From mild bell peppers to the world's hottest pepper, the Carolina Reaper, there is a pepper to suit every palate.

Whether you're a fan of mild sweet peppers or prefer the fiery heat of the world's hottest peppers.
