Column stills are more complex and sophisticated than pot stills. They can be purchased or, depending on the still design, built using readily available materials. However, column stills and pot stills work in a relatively similar manner.  Cooling water is usually circulated through a sealed compartment in the distillation column, causing the vaporized alcohol and other substances to condense in the column. This means that such a still must be attached directly to a faucet or a mechanical pump to move water from a supply into the still. If not recirculating water from a single supply, thousands of gallons of water may need to be used to make a small batch of vodka. If water is recirculated from a central reservoir using a pump, about 50 gallons (189 L) of water can be used, but the water will heat up and become less effective. Simple pot stills are akin to pressure cookers that are attached to piping or tubing. They can be constructed very easily and cheaply. Unlike column stills that are essentially vertical columns, pot stills may utilize bent or coiled tubing or piping that can be submersed in a vessel of cooling water. Pumps and large volumes of cooling water are not required, but can be used. A reflux still can do multiple distillations at one time. The packing between the condenser and the pot allows vapor to condense and trickle back down to the liquid pool. This “reflux” cleans the rising vapor and increases the purity of the vodka.
