Colonial coward, the coffee reference is to the flavour not the colour, fuckwit.

"Adored since 1959, it’s the powerful surge and settle that gives GUINNESS® Draught beer its uniqueness. Lovingly poured around the world, GUINNESS® Draught is the UK’s best selling BLACK beer.

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 our bubbles has perplexed PhD physicists. But all you need to focus on is the taste. With an initial malt and caramel flavour, GUINNESS® Draught finishes with a dry roasted bitterness. Enjoy.

Six Degrees of Preparation
GUINNESS® Draught is best served at 6°C (that’s 42.8°F), with the legendary two-part pour. First, tilt the glass to 45 degrees and carefully pour until three quarters full. Then place the glass on the bar counter and leave to settle. Once the surge has settled, fill the glass to the brim. It takes about 119.5 seconds to pour the perfect pint. But don’t fret. It’s worth the wait."

Oh yeah, and I take my coffee BLACK too...
