So, let's chat for a moment about ice, okay? There's a reason you want your cocktail ice crystal clear, and it's not just because it looks so dang pretty that way. Clear ice looks better but also melts more slowly (aka lasts longer) than cloudy ice. Plus, those clouds? They're made up of minerals and trapped gas that can add off flavors to a drink. Clear ice is also purified ice, and since that melt water is eventually making its way into your mouth and onto your tastebuds, you want it to be as pure as possible.
