reflux material question
- there have been a few articles I have been reading about distilling but
none have answered this question.
Is Alumnium ok to be used for the reflux collum. I have read that
Alum.can cause a chemical reaction in the boiler and cause poison is
this also true in the reflux.

- Aluminium works as long as it's not contacting any acids. Cooking pots
made of aluminium are sold everywhere and you do not get any reports
of poisonings. When in contact with acids aluminium forms salts which
are not very healthy. However, there salts do not vaporize so unless
they work their way out of your still in droplets they stay where ever
they are formed or below that.
Now to be practical aluminium is not good material for stills. It's
very hard to solder and since mashes are typically low on pH corrosion
is probable in prolonged use. You'll be better off using copper or

- Technically you can as long as it's only in the vapour path and not
contacting the liquid product. Metal doesn't travel well in steam but
why bother? Copper and stainless are infinitely better materials to use
due to their properties and corrosion resistance. I doubt you will find
anyone that has an aluminium column. Probably a few boilers but no
For my money steer well clear of any metals other than copper or
stainless (platinum would be nice!).
