Re: Controlling Nixon Stone head
- I tune the output rate based mostly on taste and smell.
Typically I can detect a change in smell before a
change in temperature (maybe I need a better thermometer.
actually I could run no problem with no thermometer).
After a few runs you'll have a good idea where
to set your valves, and you'll probably only be doing
small tweaks during the run. If you take off too much
and it tastes bad, don't worry. Just redistill it
again with the next batch.
On a new still or still head your first batch will
most likely need a redistill. Play with the settings
and smell/taste the output and watch the temperature.
You'll get a feel for how it behaves and you'll be
running it fine in no time.Don't stick your nose
in the cup and take a big sniff. Fan your hand over
the cup and lightly sniff. >90% alcohol vapor is
quite nasty to get up your nose. Dilute the alcohol
before tasting. You want to *taste* what's there, not
burn out your taste buds.
