2,500 - 8,000 Scovilles.
A jalapeno pepper is a fuit of the Capsicum pod type. It is a medium sized pepper when compared to other chili pepper, measuring an average of 2-3.5 inches in length but growing up to 6 inches long or longer. While originating in Mexico, it is now grown worldwide for it's popular flavor and mild heat level, which averages around 5,000 Scoville Heat Units. That is hot, but not too hot.
You'll find them served when green, but if you leave the jalapeno pepper on the plant long enough, it will turn red. The red variety are just as delicious as the green jalapeno pepper, though a touch sweeter.
A mature jalapeno pepper plant measures 2-3 feet in height and will typically produce around 30-40 jalapeno pepper pods. If you grow them in your own garden, pick them regularly, as the plant will continue to produce.
The Jalapeno Pepper - America’s Favorite Chile Pepper
America’s Favorite Chile pepper is by far the jalapeño, a thick-fleshed pepper about 3 inches long (give or take). It’s a bright green little guy that can be lovingly incorporated into just about anything, from soups to Lemonade.
The majority of our jalapeños come from Mexico, where the natives eat them as snack foods, plucking them in droves from sidewalk carts and fields. The red variety of the jalapeño is a bit milder than the green variety, and sweeter as well. They are also milder than their cousin, the serrano, another popular chile pepper, though not as widely known as our favorite, the jalapeño.
