					What is in Guinness?
Known popularly as the 'black stuff' many people are surprised when they
hear that Guinness is not actually black at all but more a ruby red
color. This is because of the method used to prepare the ingredients. The
barley is roasted in much the same way as coffee beans are roasted and
this is what gives it that unique hue.
Guinness is made from water, barley, hops and brewer's yeast. Some of the
barley undergoes a process called flaking in which it is steamed and
rolled and this gives Guinness it's distinctive black colour. It is then
pasteurised and filtered. A pint of the black stuff is that not that bad
for the hips either, it contains just less than two hundred kcal which is
in fact less than a equivalent measure of skimmed milk or orange juice.
Drought and canned Guinness contains nitrogen and carbon dioxide.
Nitrogen allows the beer to be put under high pressure without making it
fizzy. High pressure is necessary to enable the formation of tiny bubbles
by forcing the drought beer through very fine holes in a plate in the tap
which causes the characteristic surge, the widget in the cans and bottles
achieves the same effect. The smoothness of Guinness is due to the low
level of carbon dioxide and the creamy head is a result of fine bubbles
caused by the nitrogen and the dispensing method.
The reason that "Original Extra Stout has a bubbly head and has a more
fizzy constitution is due the fact that it does not contain nitrogen.
There a number of different variants of the Guinness brand, including
Guinness Drought, Guinness Foreign Extra Stout and Guinness Extra Stout.
