One garden plant that can match our summer’s heat intensity is the chili. Funny
hat they’re called ‘chilies’ when we all know there is nothing remotely ‘chilly’
about them at all!
Heat intensity of our peppers is measured in Scoville units. This is in honor of
the great American pharmacist Wilbur Scoville (1865-1942), who used human
guinea pigs to compile his scale. I hope he paid them well!
In our modern era, these Scoville units are measured more scientifically, using a
form of liquid chromatography which measures - in a more precise manner -
the amount of pure capsaicin oil.
At the very bottom of this scale, you find the sweet bell peppers, with a zero
Scoville rating. Next we come to the jalapenos - the most popular chili in Texas.
On the cooler side is the TAM mild jalapeno, with very little heat. From there
they range up to 9,000 Scovilles, the hottest being ‘mucho nacho,’ which is also
longer, fatter and wider… and great for stuffing.
Also popular in the Austin area are the New Mexico hatch chilies that we see in
late summer and fall. These Anaheims range from mild to their hottest form, the
Sandia, with a Scoville rating of 6,000.
Further up the scale we find Thai, Serrano, and the chili pequin at 25,000 to
30,000 Scovilles. At this point, there seems to be a big gap until we get to the
different varieties of habaneros. These extremely hot peppers range from
200,000 to 400,000 Scovilles with the chocolate and red Caribbean varieties
being the hottest.
And we’re not at the top of the scale yet.
The Guinness Book of World Records identifies an Indian pepper as the hottest
on the planet. Known as Naga Morich, Bhut Jolokia, or the ghost pepper, this
dastardly little pepper boasts a Scoville scale topping 1,000,000! Naga translates
as cobra or viper, and for sure, this pepper has the baddest bite of all.
Whether you eat them or not, these peppers are fun to grow and make great
conversation. They’re colorful and add great beauty to any garden.
Happy gardening everyone!
