The selling point for Crystal Head vodka is is that it is quadrupled distilled and filtered three times through charcoal followed by triple filtration over Herkimer crystals. It also comes in that nifty skull bottle designed by John Alexander and manufactured by master artisans in Milano's Bruni Glass Company.Brought to us by Dan Aykroyd. Crystal Head Vodka is perfect as a lone shot, chilled or served in signature cocktails.
