I suppose thickness is relative. Most of the peppers I grow have walls over 1/4" thick, so to me, anything less than that is "thin". As I recall, Melrose had walls just under 1/8"... thicker than most hot peppers.Interesting as some seed sellers call it “thick walled”.
There might be several strains in circulation. I first saw Melrose growing in one of SSE's trial gardens; they were growing seed from several different sources.
