Smirnoff's unique distillation process gives it a smooth, neutral taste, allowing people to enjoy its effects across a range of strengths and forms. Smirnoff vodka is distilled three times, ensuring its purity and neutral taste. Then comes the filtration process that makes the difference between premium and regular vodka - each drop of Smirnoff takes at least 8 hours to be filtered through charcoal in a 10-stage process.
