You know, I might have to invest in these because as much as I love keeping my cocktails cold..the ice really does dilute it way too much. That kills the alcohol level and makes your cocktails taste like runny cereal. I'm really interested to see how these work. They seem great for sipping your cocktails neat whether it's a quality scotch, bourbon, liqueur, rum, vodka, or tequila or cognac.
