What Is an IPA?

An IPA, or India Pale Ale, is a style of beer known for its pronounced hop character, often expressed through bold aromas, bitterness, and flavors ranging from citrus to pine. Originally developed to survive long sea voyages from England to India, the style used higher levels of hops and alcohol for preservation. Today, IPAs have evolved into a diverse family of beers, but all share a common focus on showcasing the expressive potential of hops.

IPA stands for India Pale Ale, one of the most recognizable and widely brewed styles of beer in the modern world. Today the name is almost synonymous with bold hop flavor, but the origins of the style are rooted in a much more practical concern: preservation during long sea voyages.

In the eighteenth century, British brewers exported beer to soldiers and administrators stationed in India. The journey from England to India could take months, and beer often spoiled during the trip. Brewers discovered that increasing the amount of hops and alcohol in the beer helped stabilize it during transport. Hops contain natural antimicrobial compounds, and higher alcohol levels further discouraged spoilage.

The result was a pale ale that was stronger and more heavily hopped than the beers typically consumed in England at the time. Over time this export style became known as India Pale Ale, reflecting its destination rather than its place of origin.

Hops play the defining role in modern IPAs. While all beers contain hops, IPAs showcase them prominently. Depending on the hop varieties used, these beers can express aromas ranging from citrus and pine to tropical fruit, resin, and floral notes. Bitterness is often present as well, though contemporary brewers frequently emphasize aroma and flavor as much as bitterness.

The modern IPA has evolved far beyond its historical roots. American craft brewers in particular expanded the style during the late twentieth century, experimenting with new hop varieties and brewing techniques. The result is a family of related styles that include West Coast IPA, known for bright bitterness and clarity, and New England IPA, which tends to be hazier and more fruit-forward.

Despite these variations, the defining characteristic remains the same: IPAs are beers built around the expressive potential of hops. Malt provides balance and structure, but hops shape the aroma and overall personality of the beer.

Understanding what an IPA is also clarifies something about beer more broadly. Brewing is not simply about ingredients but about how those ingredients are emphasized. When brewers choose to highlight hops, the result often falls within the IPA family.
