We start with the best grain neutral spirit, improving it with an industry-leading distillation and charcoal filtration process. Smirnoff distillation uses high column plate stills, a process that takes 24 hours.  Eventually the neutral spirit becomes a strong, pure alcohol.  This is blended with demineralised water to achieve a strength of 57% alc/vol. The Smirnoff filtration process is unparalleled.  Our blended spirit is charcoal filtered for up to eight full hours, using seven tons of hardwood charcoal to absorb impurities. Once charcoal filtered, the Smirnoff is still too strong to drink.  More demineralised water is added to reduce the vodka to bottling strength. Samples from each tank are scrupulously analysed for quality and consistency. After passing through one more filter, the vodka is bottled and ready for your favourite cocktail or mixer.
