Why would they make a Guiness without the creamy goodness of nitrous carbonation? As I sit and watch the cascade, my happiness builds into pure giddiness in anticipation of the first mouthful of frothy deliciousness. As the glass hits my lips and that dark, roasted liquid splashes into my mouth a feeling of wellness washes over me. The smoothness over my palette and down my throat explains, without a doubt, why this beverage has been around for 250 years. Plus, I love the beer mustache!
