Trying to identify peppers I bought at the local marketplace

[Misbug]

Hi everyone,
Yesterday I was buying groceries at the local market and saw these bundles of green peppers. The vendor wasn't actually able to tell me the variety but I wanted to give them a go anyway for some fermentation. At first I thought they were Anaheim peppers but after tasting one of them I can definitely say the heat level is way higher than the Anaheim (roughly two/three times the heat of a Jalapeño, had a bit of hiccup too); even the taste was actually slightly mintier and peppery than the Anaheim I tried in the past. The texture of the skin and the layout of seeds inside the fruit remind me of a Serrano, but they are less smooth on the outside than the Serrano, also they are smaller and on some fruits the colour changes drastically to vivid red or burgundy. 
Definitely not ornamental sold as edible, the taste is not grassy at all and they don't look like any of the ornamental peppers I researched. 
 
Any clue on how to label them on the fermentation jar?

+1 on green fresnos

A fresno came to my mind too when I saw most of them had pointed ends.

Looks similar to my Fresno and they are quite a bit hotter than most jalapenos. Not quite as hot as a Serrano but they can be close.

Never tried Fresnos as they're harder to find around where I live (in southern Italy there are few people interested in exotic chili peppers, great part of the production moves around the Calabrian Peppers). I researched some informations about Fresnos and yes they look similar but had a look at some pictures of sliced Fresnos and it seems the amount of seeds inside is smaller than the ones I found inside these ones I bought. Starting to think it's some kind of hybrid of Jalapeños and some type of green Calabrian peppers.
 
 
(edit) BTW now you all made me want to try Fresnos

Jalapeños fully ripen to red. The ones you're asking about were picked green, meaning it has nothing to do with the color of a parent.

Oh ok I see. Still learning about growth and cultivation. Thanks for the clarification

If you decide to grow Fresno i highly recommend you let them ripen to red. Green are ok but ripe they are better. Serrano are better green if you want something similar to a green Fresno.

i grew fresno last year and they looked very much the same before turning red.

what is the size of your peppers? my pods were about 3.5 inches or so. here is a red one from last year with a couple of banana peppers.
