Its a bit early for gathering chilli's, mine are no where near ready.

The trouble with saying a chilli is med or hot, is a bit vague, and is
very much down to the person tasting it. A bit like ordering a curry
??

A scale of chilli hotness exists which is measured in Scoville units.
This test was developed back in 1912 by Wilbur L. Scoville using a
human tasting panel. The Scoville scale is still in use although the
human panel has been replaced by a high-pressure liquid chromatography
machine.
