The bitter style came from brewers who wanted to differentiate these ales from other mild brews - enter pale malts and more hops. Most are gold to copper in color and are light bodied. Low carbonation. Alcohol should be low and not perceived. Hop bitterness is moderate to assertive. Most have a fruitiness in the aroma and flavor, diacetyl can also be present. These are traditionally served cask conditioned, but many breweries have bottled versions.
