Guinness Draught is one of best-selling imported beers in the USA. A unique mix of nitrogen and carbon dioxide helps create Guinness Draught's liquid swirl that tumbles, surges and gradually separates into a black body and smooth creamy head. The rise and fall of bubbles has perplexed PhD physicists. But all you need to focus on is the taste. With an initial malt and caramel flavour, and finishes with a dry roasted bitterness. Enjoy!
