In the 18th century, British brown ales were brewed to a variety of strengths, with
original gravities (OG) ranging from around 1.060 to 1.090. Around 1800, brewers stopped producing these types of beers as they moved away from using brown malt as a base. Pale malt, being cheaper because of its higher yield, was used as a base for most beers, including
porter and
stout. The term "brown ale" was revived at the end of the 19th century when London brewer Mann introduced a beer with that name. However, the style only became widely brewed in the 1920s. The brown ales of this period were considerably stronger than most modern English versions. In 1926, Manns Brown Ale had an original gravity of 1.043 and an ABV of around 4%. Whitbread Double Brown was even stronger, an OG of 1.054 and more than 5% ABV. The introduction of these beers coincided with a big increase in demand for bottled beer in the UK. In the 1930s some breweries, such as Whitbread, introduced a second weaker and cheaper brown ale that was sometimes just a sweetened version of dark Mild. These beers had an original gravity of around 1.037.
North American brown ales trace their heritage to American
home brewing adaptations of certain northern
English beers, and the English influence on American Colonial Ales. ==Description==
