India Pale Ales
In
the early eighteenth century as Porters
were becoming hugely popular in England, the British East India
Company was establishing large colonies of merchants, tradesmen and
British soldiers in India. And while England was busy building an
empire on which the sun never set, demand for British beer was
building in India.
The sea voyage to India took ships to the south Atlantic, around the
horn of Africa and finally to India on a journey that would
typically last about six months. The changing temperatures and
rolling seas wreaked havoc with the beer and the Porters typically
arrived sour, stale and flat.
The
Royal Navy was eager to solve this problem and provide fresh, tasty
beer for British soldiers and sailors, so they put the challenge in
the 1780's to British brewers of the day to brew a beer that would
last through the voyage to India. George Hodgson of the Bow Brewery
in London surmised correctly that higher hop and alcohol levels
would help to preserve his own Pale Ale
through the difficult sea conditions, so he brewed a high hopped,
high alcohol version of it that did the job, eventually earning the
name India Pale Ale, or IPA for short. Hodgson's beer
arrived in quite pleasant condition in India and soon other brewers
like Bass followed suit, creating their own IPAs and the beer
market in India exploded.

As Hodgson brewed his beer well over 200 years ago, we cannot be
completely certain what it tasted like, but it seems clear that his
export version of an IPA was extremely bitter and very high
in alcohol. Other brewers copying Hodgson's recipe found that the
high level of hops created a longer fermentation time and in order
to shorten that time and to brew more beer, hop levels were reduced
for the home country versions of IPA.
Over time, high hop and alcohol levels faded in popularity and
during the twentieth century, the British version of the IPA
was reworked accordingly. Many beer experts theorize that today's
American IPA is closer in taste to George Hodgson's original
IPA than many of it's current British counterparts. That
being said, there are two relatively distinct types of IPAs,
the British and American versions, plus the "Imperial" or "Double"
versions of the American style.
IPAs
are very strong flavored, sturdy beers and as such they will hold up
to many spicy and rich foods. Spicy Asian foods like Thai are
perfect for them as well as Indian curry dishes (they are India
Pale Ales, after all!). Sharp cheeses like limburger and many bleu
cheeses are also well suited to IPAs. Salmon also pairs nicely with
IPA's, but don't forget about the traditional beer and pizza pairing
with this style! And drink an IPA from a pint glass while you're at
it.
English IPAs
The British invented IPAs, as you have probably just read. Yet the
India Pale Ale today is markedly different from the original IPA
brewed for export to India by George Hodgson. From a production
viewpoint, it was difficult to maintain the high hop levels that
Hodgson pioneered in his original recipe as the higher hop levels
slowed the fermentation process and more hops were, of course, more
expensive. Additionally, it was soon found that while higher hops
levels found an audience, an IPA with less hops than Hodgson's
version was even more popular among British drinkers at home.
British IPAs today typically range from 5% to 7.5% abv and from 40
to 60 IBUs. IBUs are a measurement of bitterness in a beer that
is calculated by specifics of the brewing process itself. The higher
the IBU number, the more bitter a beer should be.
British IPAs are generally more balanced than their American
counterpart, meaning that they have a higher malt content and a
lower hop content than American IPAs (more sweet, less bitter!).
American IPAs
In America,
IPAs have taken a more extreme route to popularity. Blessed with a
relatively abundant hop crop and very tasty, high alpha acid hops
(high alpha acid hops are more bitter than low alpha acid hops),
American brewers have created IPAs that harken back to George
Hodgson's original recipe with higher hop and alcohol levels. Almost
every micro brewer produces and IPA these days and they are among
the most popular beer styles with American craft beer drinkers who
crave their citrusy or piney hop flavors.
American
IPAs are typically a little bit higher in alcohol than their British
cousins and while the hop content can be similar, many American IPAs
go far beyond the British IPA in bitterness, sometimes getting to 70
or even 80 IBUs. The lesser malt content of American IPAs is usually
overshadowed by their high hops.
The flavors found in American hops are highlighted in American IPAs
and range from pine to resinous to citrus. In many IPAs, grapefruit
flavors are very distinct.
Imperial & Double IPAs
A
true showcase for hop flavor is to be found in the Imperial or
Double IPA. Created by American brewers to satisfy the growing
demand for extremely high hopped beers, Imperial IPAs are American
IPAs with extreme hop contents. The word "Imperial" is used to
signify an extreme beer, but the word "Double" is often used in its
place.
Imperial
IPAs usually range well over 7.5% abv and can have IBUs that measure
into the 100+ range. There is a theory that most humans can't taste
bitterness anywhere over the 90 IBU count, but no matter your taste,
it is easy to be overwhelmed by the high hop content of these
extreme beers.
