This answer might vary between types of chillies, but I'm curious to know when they're hottest.

McGee writes: "Capsaicin appears to accumulate in the fruit concurrently with the pigment during ripening". (On Food and Cooking, p.212) So yes, chilis get hotter as they ripen (that is, as they turn from green to red). Many chili varieties are picked and sold in stores while still unripe and green (e.g. jalapeño, serrano, poblano), but you will occasionally see ripe, red ones in stores. All of the dried chilis I've seen in stores have been completely ripened before drying (e.g. chipotles, which are smoked, dried red jalapeños and anchos, which are dried, red poblano peppers). I've personally observed this effect with padron peppers, which are usually picked green and mild, but can ripen to red, hot peppers if left on the plant. |

Most chiles become more picante as they ripen. But they also become much sweeter. Jalapenos are a good example. Red jalapenos are much more delicious than green ones. Most of the 'heat' is in the seeds and the tissue connecting the seeds to the capsule. You can pare those parts out with a small knife. I eat most of my ripe jalapenos right in the garden, pocket knife in hand! |

Not really. The chemical that gives chillies their heat is called capsaicin. It is an extremely stable alkaloid, and so remains potent even after a long period of time: note, for example that dried chillies and even chilli flakes are still hot. |
