This is a great article - thank you for posting! I've heard a small craft distiller refer to their still as a combination pot & column still. Does that mean the wash boils in the pot and then is fed into the top of the columns and passes through the subsequent columns?
Also, if a distiller has fewer than 4 columns – say 2 for example – would that mean that they would need to do multiple distillations to make it pure?
Thanks again – still learning and have so many question :)

What your referring to is a hybrid still where the vapour from the pot still is directed through a column for rectification before reaching the condenser. Hybrid stills can have a column sat directly on top of the pot or, one or more columns alongside the pot. It's not the number of columns but the number of plates in the column(s) that matter as each plate is a distillation.
