Pale Ale (British or English Style).

The term Pale Ale and Bitter are more or less interchangeable today, British customers simply began calling what the brewers called Pale Ale by the short quick phrase "Pint of Bitter, Please" and the term stuck.
The Pale in the name is more a reference to the pale malt used in making this beer than in the actual colour of the final beer. It is "Pale" in reference to the Porter which was so common at the time but is a dark golden colour often with red or orange shades. Usually a thick slightly off white head and a fairly full mouth feel.
The tastes are usually quite hoppy and the bitterness definite but mild and lasting.
The malts often provide a nutty or doughy taste which is quite pleasant. In traditional British Pale Ales the hops used often show an earthiness in the taste.

This style of beer is usually better if not too cold, I like to leave the bottle out of the fridge for a half hour or so before drinking it.
