Ever heard of Crystal Head Vodka? I happened to spot its unique bottle at my parents’ house a few weeks ago. (Yes, it was still full.) I hadn’t heard of it before, but it turns out it’s actor, musician and writer Dan Aykroyd’s special blend, which is said to be free of any additives, is quadruple-distilled and then triple-filtered through polished crystals called Herkimer diamonds. And the skull-shaped bottle is cool enough to keep (plus it was designed by world-renowned American artist John Alexander), so why not cruise over to the BevMo at 3106 Arden Way on Wednesday, buy a bottle, and have Aykroyd sign it? You can pre-order yours and have it waiting for you when you arrive. Head over between 4 p.m. and 6 p.m., and make your bottle of Crystal Head even cooler!
