Cream ale is a misnomer. There's no "creaminess" to it - it's basically the same as an American Lager. I prefer to brew mine with a little more mouthfeel which I get by offsetting the high percentage of (body-thinning) corn with a dextrin rest and yeast selection.
It's a style sometimes used as a base for different flavors like orange and vanilla, but at it's best, it's a straight-up grain and hops sort of beer. If I call my cream ale something else, most people like it better. It's very odd.
Here's an excerpt from the BJCP:
History:
A sparkling or present-use ale that existed in the1800s and survived prohibition. An ale version of the American lager style. Produced by ale brewers to compete with lager brewers in Canada and the Northeast, Mid-Atlantic, and Midwest states. Originally known as sparkling or present use ales, lager strains were (and sometimes still are) used by some brewers, but were not historically mixed with ale strains. Many examples are kräusened to achieve carbonation. Cold conditioning isn’t traditional, although modern brewers sometimes use it.
Characteristic Ingredients:
American ingredients most commonly used. A grain bill of six -row malt, or a combination of six-row and North American two-row, is common. Adjuncts can include up to 20% maize in the mash, and up to 20% glucose or other sugars in the boil. Any variety of hops can be used for bittering and finishing.
Style Comparison:
Similar to a Standard American Lager,
but with more character.
