Column-distilled. Quartz and sand filtered. Flavored with 2 grams of carrots per 10,000 liters, the bottle reads "Vodka with natural flavoring" Very very subtle carrot sweetness on the nose but it is very nice. Slightly oily textured, especially for a column distilled vodka. This vodka has a unique earthy flavor. Overall, this is a unique tasting product with no qualities that are off. Interesting, but maybe not a mainstream flavor profile.
