Each bottle of Portobello Road Potato Vodka is distilled from almost three kilograms of British potatoes. The spirit is first distilled to a very high level of purity using the process of continuous distillation- and is then distilled once more the old fashioned way- in a copper pot still; this time in the presence of sacrificial copper- which helps to remove any unpleasant tasting flavour compounds. We then add the purest water and bottle it.
