Ran my new reflux still for the first time on 05-07, Wednesday
After I took off foreshots, it stabilized at 78.3*C for nearly the
entire run which means the stuff coming out was 96% ABV. Probably lost
some due to evaporation, but wow.
The takeoff rate was pretty slow because I'm using a hack until I buy
a proper needle valve. 500ml per 2 hours. But still, 96%!
I fed some old tails and heads from other runs into the boiler with most
of a bucket of 12% ABV sugar wine that had breakfast cereal soaking in
it for flavor. Some of the breakfast cereal notes carried through but
it smells and tastes ultimately like a rum. Dilute down to the low 40%s
and I ended up with 6 liters from 12 hours of operating time.
Based on my math, the ~80cm of packing in a 2" pipe is achieving 13 or 14
"plates" worth of distillation when refluxing. A stripping run normally
takes me 8 hours to pull out 4L of 40% that have a lot of off flavors,
and running 18L of ~35% takes 9 hours to extract ~3L of "hearts" around
70%. So big picture, the reflux saves a lot of time for producing a
clean, strong spirit.
going to do another reflux experiment next week with the bran sugar wash,
curious how it will compare to the cereal sugar wash. I suspect it will
taste like a pretty good whisky. There are hints of whisky flavor in my
breakfast cereal reflux (some of the heads/tails I dumped in were from
my bran sugar wash spirit run) but it ultimately tastes more like rum
than anything.
