Our vodkas are all filtered to clear the liquid of impurities and achieve absolute clarity. Our Russian birch charcoal filters form chemical compounds that improve the taste and aroma . At the same time, a sharp burning or bitter notes in the aftertaste are eliminated. Our filtration process with quartz from the Ural Mountains generates static electricity that changes the molecular structure. This gives the vodka a softer taste. We also use silver, a very effective, antimicrobial agent to further refine our vodka.
