Marquis Vodka is a Miami-based brand of vodka produced in Poland. It is distilled by the famous Polmos Bialystok distillery, Poland, from hand selected rye grain using Europe's tallest column stills. Master Distiller Henryk Wnorowski ensures hand-finished quality control through certification conducted by Kema Quality B.V, a Dutch certification unit and an Integrated System of Management. Polmos Bialystok uses the most up to date technological equipment in its manufacturing and purification processes, such as water conditioning plants based on reverse-osmosis, and highly efficient bottle filling units ensuring bottling is in an antiseptic environment. Once filled, each bottle is given a quality assurance hologram and are sealed with hand-applied ribbons. Each bottle is then hand checked for any imperfections prior to packaging and then exported to the United Kingdom.
