The history of IPA: from colonial myth to truth and craft

IPA, that is India Pale Ale, is today the most popular style of craft beer, and its name carries a colourful, colonial legend. The myth holds that IPA was invented specially, by adding lots of hops, to survive the long sea voyage to British India without spoiling. It is a beautiful story - and largely untrue. The real history of IPA is more complex and more interesting: it is the story of an already existing beer, the role of the long journey and the town of Burton-on-Trent, and finally a spectacular revival in the era of craft. Here is a guide to the history of IPA: what the colonial myth is, what really happened, what role Burton played and how IPA became the banner of the craft revolution.

The colonial myth

Let us begin with the famous legend that almost every beer lover knows. The myth holds that George Hodgson and his Bow Brewery in London invented the heavily hopped IPA in the mid 18th century, because ordinary beers sent to India arrived spoiled due to the long journey and the heat. According to this tale Hodgson deliberately added an enormous amount of hops (a natural preservative) and raised the alcohol, so the beer would survive the voyage. It is a beautiful, romantic story, linking beer with the British empire and a deep-sea adventure. The problem is that almost all of this tale is untrue. It is one of the most enduring myths in the world of beer, repeated on labels and in bars. Understanding that the popular history of IPA is largely a legend is the starting point for learning the truth. It is time to debunk a few myths. We cover hops themselves more in hops in IPA.

What really happened

The truth is more complex and less romantic. First, other beers - porters, pale ales, brown ales - were shipped to India for decades without significant spoiling. This undermines the basis of the myth: ordinary beers did not arrive spoiled en masse at all. Second, there is no evidence that Hodgson specially formulated his pale ale with an enormous dose of hops for the India trade. The beer he exported was a variant of an already existing style called October Beer - a stronger, naturally well-hopped beer, brewed in the autumn and maturing in cellars for two years. Hodgson therefore did not invent a new beer for India - he took an existing, strong, hoppy beer and sent it overseas. Understanding that IPA is an adaptation of an existing style, and not an invention for the colonies, is the key to the real history. The myth simplifies and romanticises reality.

The role of the long journey

Although Hodgson did not invent IPA for India, the journey itself played an important role - just a different one than the myth holds. The key was not that the hops protected the beer from spoiling, but what the journey did to the flavour. The long voyage through tropical waters, with swings of temperature and constant rocking, acted like accelerated maturation. October Beer normally needed two years of cellar ageing to reach a mature, refined flavour. But during the four-month journey to India this maturation happened much faster - the beer arrived perfectly matured in four months instead of two years. It was precisely this effect, not preservation, that made the beer so popular in India. The journey was therefore an accelerated cellar, not a test of survival. Understanding this difference debunks the myth while keeping the real role of the voyage. It is a truth subtler but more interesting than the legend. It is maturation in motion, not a fight for survival.

A table: myth versus truth

Let us gather the myth and the truth in one place:

The table shows how far the popular legend diverges from the facts. The real history of IPA is less romantic but more fascinating.

Burton-on-Trent and the water

An important chapter of the history of IPA is the shift of its centre to Burton-on-Trent. At first the beer trade to India was dominated by London’s Hodgson, but around 1820 the dominance passed to the town of Burton-on-Trent. The reason was surprising: water. The breweries of Burton, like the famous Bass, used local water rich in gypsum (calcium sulphate), ideal for brewing hoppy pale ales. This hard, gypsum water showcased the bitterness of the hops and gave a clearer, more expressive beer than the soft water of London. This gave the Burton breweries an enormous advantage in producing IPA. Interestingly, it is only in 1829 that the first beers marketed as India Pale Ale appear - the name of the style therefore came later than the beer itself. Understanding the role of Burton water shows that the success of IPA was also decided by a local raw material, not just trade. It is geology turned into beer flavour. We cover water in beer more in hops in IPA.

Decline and revival in craft

Like many classic styles, IPA went through a period of oblivion, only to be spectacularly reborn in the era of craft beer. For most of the 20th century IPA declined, becoming a weaker, less hoppy beer than its 19th-century prototype - the style almost lost its former character. Everything was changed by the American craft revolution at the end of the 20th century. American craft brewers revived IPA, adding to it enormous amounts of aromatic American hops with notes of citrus, resin and tropical fruit. Thus the modern IPA was born, and the style became the banner of the whole craft movement - the most popular and most recognisable beer of the revolution. Today IPA is not one style but a whole family, of which more in a moment. Understanding this revival shows how a forgotten style returned as a symbol of a new era of beer. We cover the IPA family more in the IPA family.

The family of modern IPAs

The modern IPA has grown into a whole family of varieties, far beyond the original style. West Coast IPA is the classic of the American revival: clear, dry, strongly bitter, with citrus-resin hops. Hazy IPA (New England IPA) is a cloudy, juicy, fruity beer of low bitterness, exploding with tropical aromas. Double and Imperial IPA are stronger, more hoppy versions. And Cold IPA is a newer, experimental variety, combining the hoppy character of IPA with the clean, dry profile of lager (cold) fermentation, giving a crisp, heavily hopped beer. This shows that IPA is not a closed style but a still evolving family, driven by the creativity of craft brewers. From its colonial roots IPA has become a field of constant innovation. Understanding this diversity shows how alive and dynamic this style is today. It is a history that is still being written. We cover craft more in craft beer.

How to sense it in the mug

A modern IPA is easy to recognise by its dominant hops. You sense above all an intense aroma and flavour of hops: citrus (grapefruit, orange), tropical fruit (mango, passionfruit), pine resin, sometimes floral notes. The bitterness ranges from moderate (Hazy) to clear (West Coast). West Coast IPA is clear, dry and bitter; Hazy cloudy, juicy and fruity of low bitterness; Cold IPA crisp and clean. The malt base is usually discreet, so as not to cover the hops. If a beer hits with an intense, fruity-resinous aroma of hops, it is without doubt some IPA. It is worth comparing a classic West Coast with a cloudy Hazy, to feel the range of the family. Serve IPA fresh and lightly chilled, because the hop aromas fade quickly. Over time you will learn to recognise the varieties of IPA by the style of hopping. It is the most hoppy family of beers.

The essentials in brief

Let us gather it up. The popular myth holds that IPA was invented with lots of hops to survive the voyage to India without spoiling - but this is largely untrue. Other beers also arrived in India intact, and George Hodgson did not invent a new beer but took the existing October Beer. The real role of the journey was the accelerated maturation of flavour, not preservation: the beer matured in four months instead of two years. The name India Pale Ale appears only in 1829, and the centre of production shifted to Burton-on-Trent thanks to its gypsum-rich water. After a decline in the 20th century IPA was reborn in the American craft revolution and became the banner of the movement, growing into a family: West Coast, Hazy, Double and Cold IPA. Now you know the real history of IPA, far from the colonial myth.
