It was the American craft brewers who picked up the legacy of India Pale Ales and reintroducing heavily hopped beers, except why simply replicate a somewhat neglected British style when so many great hops are available in the USA? Hops such as Cascade and Centennial characterise this style of stronger (around 5%) full-flavoured and heavily hopped beer, with brewers such as Sierra Nevada and and Anchor pioneering the style in the early 1980s. Today you’ll find this clean, hoppy style made (with American hops) all over the world.
The legacy in question dates back to the 19th century when strong hoppy beer (though not as hopped as some you’ll find these days!) from Britain was sent out to colonial India, benefiting from the conditions of the journey by sea, and gaining popularity ahead of other pale ales and beers of the time. Eventually Hodgson’s introduced their East India Pale Ale to the UK market, made fashionable by the interest in the empire and all things from India during the reign of Queen Victoria. Even back then some American hops were used, alongside those from Europe, although a majority of favoured English hops were used. Over the years the style typically became milder, lighter and less hopped until relatively recently.
