Reyka is distilled in small batches to ensure exceptional quality. Each distillation takes about 5 hours and makes only 330 cases. By vodka standards, that's tiny. We distill Reyka in two of the few Carter-Head stills in the world. The Carter-Head stills' high copper level gives Reyka unparalleled smoothness from a single distillation. Iceland is full of lava rocks. We use them to filter our vodka, giving it a crisp, clean taste. You could say it's "vodka on the rocks." But we'd rather you didn't.
