"It’s the Water! Crater Lake in the Cascade Mountains of Oregon, long regarded as the purest water in the world, is our inspiration for Crater Lake Vodka. Melting snow, percolating through porous lava rock, forms the source of this extraordinary water. Mimicking this natural process, we filter our vodka ten times through charcoal and crushed lava rock. Then, a portion of each batch is rested briefly in new American oak. The result is vodka recognized internationally for its exceptional smoothness. You will notice a soft, spring water character with a hint of vanilla on the finish."
