Cameron,

You may be mistaken.  For one thing moving to Denver would lower the
boiling point of capsaicin too.  But I think there's another process
going on here.

Capsaicin:

Melting point: 65 oC (Ref 8, 1811)
Boiling point: 210-220 oC at 0.01 torr pressure (Ref 8, 1811)

8: The Merck Index. 12th Edition. Merck & Co., Inc. Whitehouse Station,
NJ. 1996.

Note the pressure--that's a pretty hard vacuum.  Got this from Mike's
Pepper Garden.

95% ethanol/water is a constant boiling mixture and the ethanol/water
proportions don't change, as you know.  I thought perhaps there was
something analogous with steam stripping going on here, but that doesn't
apply to miscible compounds.

If he's boiling it a long time then capsaicin is lost.  After all, it's
going into the air, not a fractional column.  But judging from the
boiling point I wouldn't think much would be lost.  Hydrolysis perhaps?
Wimpy habaneros?
