Pale Ales
Pale Ale
Of British origin, this style is now popular worldwide and the use of local ingredients, or imported, produces variances in character from region to region. Generally, expect a good balance of malt and hops. Fruity esters and diacetyl can vary from none to moderate, and bitterness can range from lightly floral to pungent.
American versions tend to be cleaner and hoppier, while British tend to be more malty, buttery, aromatic and balanced.
Average alcohol by volume (abv) range: 4.0-7.0%
IPA (India Pale Ale)
The American IPA is a different soul from the reincarnated IPA style. More flavorful than the withering English IPA, color can range from very pale golden to reddish amber. Hops are typically American with a big herbal and / or citric character, bitterness is high as well. Moderate to medium bodied with a balancing malt backbone.
Imperial IPA
Take an India Pale Ale and feed it steroids, ergo the term Double IPA. Although open to the same interpretation as its sister styles, you should expect something robust, malty, alcoholic and with a hop profile that might rip your tongue out. The Imperial usage comes from Russian Imperial stout, a style of strong stout originally brewed in England for the Russian Imperial Court of the late 1700s; though Double IPA is often the preferred name.
You can thank west coast American brewers for this somewhat reactionary style. “Thanks!”
