Thinking that today the average English person drinks from green glass bottles with labels written in Italian is incredible. Fortunately, there are still - and again - those pubs where you walk in and read words like “Mild,” “Porter,” or “Stout”: know that these names are among the oldest to have survived to this day, even though the products they refer to are very different from those of the past. Today many breweries also produce a Bitter, and this is the style we immediately think of when we talk about England, but you should know that it is one of the latest to appear in the historiography of beers from across the Channel.
This article explains that the term - and therefore the style - “Bitter” originated as an offshoot of the first English Pale Ales.
