Re: [new_distillers] ruined fermentation?
- I don't know for sure if it's the source of your
problem but galvanized steel should not come into
direct contact with the alcohol vapour! Use stainless
or brass instead, even now threaded copper fittings
and adapters are available.
There are several grades of galvanization and some can
contain varying levels of lead as well as a host of
other chemicals and metals that will create toxic
gases and by-products that will contaminate your
spirits and WILL poison you when exposed to heat!
Plastics are another area of concern, certain plastics
are just not safe when heated above a specific temp or
exposed to alcohol vapours, eg; rigid PE plastics and
HDPE specifically are what I am willing to use... PVC,
CPVC, ABS, etc are some I would not use with my
spirits ! Even in soft PE plastics there are
"elastomers" which are added to make the polyethylene
pliable which will leach with extended contact with
some solutions and solvents!
No need for unnecessary risks!

happy new year to all out there!
i got a question. i have a fine 39" reflux column with
a 15 US gallon
beer keg as a boiler. the piece that couples the 2 is
kitchen mixing bowl with holes drilled in the bottom
and an adapter
that the column slides into. i use cork as gaskets and
there are no
all the stuff that i have fermented so far (5 batches
rum))has smelled delightful, but the spirit i get is
stuff! last friday i got 3 liters of 80% out of 25
liters of mash.
that is before i gave up in disgust and tossed the
is it possible that there is a cockup in the ferment?
everything properly and have a bubbly thing in the lid
of the food
grade fermenting bucket that stops trash coming back,
but no matter
what i do, i get nothing usable. to try and describe
the mouth feel
of the spirit - it doesn't taste anything like booze,
but feels like
it evaporates instantly on the tongue and leaves a hot
feeling in the
mouth. the wife says it smells like mail polish
remover! and that is
acetone. i don't know if there is a chemical
acetic acid and acetone, but is it possible that the
brew goes bad
before i distill? how would i be able to tell?
i also know that the adapter that joins the column and
the bowl on
the boiler isn't stainless steel. i think it is
that make a difference?
any pointers will be MOST appreciated!
