1,001 things every woman should know…
Why is Guinness black?
It’s not. It’s a deep, ruby red because its malted barley is roasted before brewing (turning it dark red). But it’s so dark that the creaminess of the head makes it look black. So how come the head’s so white, then? Guinness taps have a special widget in them that releases nitrogen into the beer as it is poured, creating tiny bubbles. This, combined with the pressure of the tap, gives the head its ‘whipped’ texture.
