Pale ale is a style of beer that gets its name from its golden to amber color. It's brewed using "pale malt," which is dried in a special way. This term first showed up in England around 1703 for beers that were much lighter than others at the time because the malt was dried with a special kind of charcoal called coke.
By the 1830s, people often used the words "bitter" and "pale ale" to mean the same thing. Customers started calling these beers "bitters" to tell them apart from other less hoppy beers. Today, there are many different kinds of pale ales, all with unique tastes and strengths, depending on how they are brewed and how many hops are used.
One very popular type is the American Pale Ale, which became famous in the 1970s and 80s for its bold use of American hops like Cascade. Breweries like Anchor and Sierra Nevada really helped make this style a hit! You can also find Amber Ales, which are a bit darker and have a lovely copper or light brown color from special malts.
Another interesting one is Bière de Garde, a "keeping beer" from France, traditionally brewed in colder months and aged. And of course, there's India Pale Ale, or IPA, which was originally developed in England to stay fresh during long journeys to India. Some pale ales can even be incredibly strong, with much higher alcohol content than typical beers!
