25 Most common peppers used in hot sauce

There are many varieties of hot peppers but all of them may not be used to make hot sauce. Some of the more common peppers used for various cuisine have a lower level of heat to them. However, peppers used to make hot sauce can reach some of the most extreme heat levels.

There are about 25 varieties of hot peppers that are most commonly used to make hot sauces. They are used to boost the heat of a sauce and are often overlooked for the flavor they add. Other hot pepper varieties may be used because of their availability or abundance of products available.  

Three things distinguish each variety of pepper from each other and they are heat level or the amount of capsaicin, the color, and the flavor. There are high and low levels of heat within each variety of pepper and there can also be an assortment of colors and flavors from the same species.

This is the perfect document to guide you through making gourmet hot sauce!…and it starts with selecting the right hot pepper. Read more below…

The level of heat defines a hot pepper

There is a huge difference in the level of heat from one pepper type to the other and there can be variance within that pepper species as well. The intensity of heat from a hot pepper and hot sauce is measured in Scoville Heat Units or SHU. The SHU of a pepper is also an indication of how much capsaicin a pepper contains.

Capsaicin is responsible for hot pepper heat

Capsaicin is the chemical compound in a pepper that is responsible for heat. This occurs as a natural deterrent to prevent natural predators from consuming the fruits. It seems to work the opposite for humans because they seem to be drawn toward hot sauce. The hotter the pepper, the more capsaicin it has and this is a good thing. Capsaicin has many health benefits to it but the advantages could be lost in the hot sauce. Capsaicin does not have any flavor to it so the amount of heat in a hot pepper will not affect the flavor of a hot sauce.

Ripeness makes a difference in flavor and heat

Peppers will turn different colors throughout the ripening process beginning with green. If they do not reach their full ripeness, they will very bitter in flavor and firm in texture. Tabasco® uses a bright red colored stick to determine the ripeness of each crop so they can harvest at just the right time. Some varieties of hot peppers will change colors as they are left on a plant to ripen, and this will lead to an increase in heat level.

Soil conditions determine heat level

The proper pH balance of soil can make a difference in how hot the peppers will become. However, even the most acidic soil will not make a bell pepper any hotter. Growing peppers in soil with lower acidic levels can be achieved by adding organic matter like compost or natural acids like vinegar. The soil conditions won’t affect the color of hot peppers as much as the right harvest time.

Hot peppers come in a variety of colors

Throughout history, a hot pepper has always been commonly associated with the color red and this has been synonymous with heat. The color of a hot pepper can range from yellow to pale and dark greens into orange and red hews. There are some varieties such as a chocolate habanero that are dark brown and a purple Jalapeno that is…well…purple. These colors will change differently for each pepper variety throughout the growing season and this will make a difference in the flavor as well.

Hot peppers are full of flavor

Aside from heat, many people may not be aware that a pepper has a variety of flavors as well. Flavor, like heat, can vary from pepper to pepper. I love the sweet and fruity flavor of a ripe Red Bell pepper…but I wish they had just a little heat to them. I make sauces with them but also include a spicier pepper as well. A jalapeno or habanero combines nicely with the flavor of orange or red bell pepper.
