===Robert Stein===
In 1828, Scotsman, Robert Stein, patented a continuous still that fed the "wash" through a series of interconnected pots. Piston strokes were used to vapourise the wash and feed it into a horizontal cylinder which was divided into a series of compartments using cloth.<ref name=":2" /><ref>[https://books.google.com/books?id=5VEEAAAAQAAJ&dq=robert+stein+distillation&pg=PA538] December 1828 Patent for Stein</ref> The Stein still offered improved [[fuel efficiency]] compared with the traditional pot still and was the first continuous still to be employed commercially in Scotland, finding use at the Kirkliston (1828), [[Cameron Bridge#The Cameronbridge Grain Distillery|Cameron Bridge]] (1830), Yoker (1845), and Glenochil (1845) distilleries.<ref name=":2" /> However, as the still did not allow for siphoning off of the pungent fusel oils, the spirit produced was not highly rectified, and still needed to be stopped frequently for cleaning.<ref name=":2" />
