Abstract
As America makes a shift from the traditional American lager to full-flavored beers, the India Pale Ale (IPA) is prolific in the craft beer market. The uniquely bitter profile of this brew pub favorite inspires brewers to push the style to the limits, generally with great success. What many don’t know is that the style, as described by the Beer Judge Certification Program (BJCP) style reference guide, was originally created out of necessity rather than innovation. This paper will take a look at the beginnings of the India Pale Ale and its impact on today’s craft brew enthusiasts.

India Pale Ale: Present
It will come as no surprise to craft beer enthusiasts that an India Pale Ale (IPA) is on the American Homebrewer’s Association’s (AHA) 2013 list of the best beers in America for the fifth year in a row (American Homebrewer's Association, 2013). Zymurgy, the journal published by the AHA and named for the branch of applied chemistry dealing with fermentation, places IPA’s in 7 of the top 10 positions with an impressive showing throughout the top 50. With the American IPA capturing the hearts of commercial master brewers and the homebrew “weekend warrior” alike, many accept the decidedly bitter profile as another choice of style designed by innovative craft brewers of late. However, the style originated out of a particular necessity that is almost as old as beer itself.
The Hop
The Beer Judge Certification Program’s (BJCP) style guide defines the IPA as a beer having a “moderate to moderately high hop aroma” with a “medium to high hop flavor” and “an assertive hop bitterness” (Zainasheff, England, Hieronymus, Fitzpatrick, & DePiro, 2013). Simply put, an IPA is an IPA because of the brewer’s unique use of hops. Hops supply the bitter properties enjoyed by enthusiasts but became the tool of choice due to its antibacterial/bacteriostatic, or preservative, properties (Priest & Campbell, 2002).
While ancient brewers often used plants with decidedly bitter properties, hops have been linked to brewing as far back as 822. Cornell noted that, in the writings of the Abbot of a Benedictine monastery in Northern France, instructions for abbey tenant duties dictated that if gathering did not produce enough hops, “the porter should take steps to get more from elsewhere to make sufficient beer”. Later, in 1150, the first real indication that brewers were using hops specifically for their preservative qualities appeared in writing. (Cornell, 2005).
The Bow Brewery and the East India Company
By the middle part of the 1700s, it was well known among brewers that beer would survive in proportion to the amount of hops used in the recipe. Moderately hopped pale ales were commonplace and a favorite of British tavern patrons. With trade colonies well-established in India, the men of the East India Company required a beer that was suitable for surviving the hot climate. Modern beer lore holds that George Hodgson of the prominent Bow Brewery in London created the IPA for that purpose. Hodgson is likely credited with creating the IPA because of a proliferation of the Bow Brewery brand in the market due to Hodgson’s unique policy of extending credit to the ships’ captains. However, the reality is that all of the prominent brewers of the time prepared heavily hopped porters and a pale ale, Cornell stated, that would later be referred to as “pale ale for India” or “pale ale prepared for the east and west India climate” (Cornell, 2005). This, of course, became the modern IPA.
Conclusion
As the American craft beer paradigm evolves, many adaptations of popular or historical beer styles are presented to the enthusiast. It’s no surprise that, in a market that produces beers outside of normally accepted style guidelines, the uninformed could assume that IPA is a late entry. However, this examination shows that the style, as it exists today, started with discoveries of the 2nd century and was popularized almost 300 years ago.
