Craft IPA Beer

August 1st is National IPA Day, a celebration of India Pale Ale (photo #1), America’s fastest-growing category of craft beer. It’s so hot that Spielgau has developed a special IPA glass (photo #2) to best show off its flavors and aromas.

India Pale Ale is a highly-hoped beer style within the broader category of pale ale, a category that originally referred to an ale that had been brewed with pale malt.

India Pale Ale is not a beer created in India; but was created in England for Brits living in India. Here’s the scoop.
 
THE HISTORY OF IPA

The history of IPA, a 19th-century creation, begins in ancient times.

Beer has been brewed since before written history. Archaeologists date it to around the 6th millennium B.C.E. The oldest known recipe found to date is one for brewing beer, found on stone tablets in Sumer, in southern Mesopotamia.

The “fertile crescent” or “cradle of civilization” between the Tigris and Euphrates Rivers was the original area for much cultivation of hitherto wild foods, and much food innovation. Today, the area includes modern Iraq, northeastern Syria, southeastern Turkey, and southwestern Iran.

By 4000 B.C.E., the Babylonians were brewing at least sixteen varieties of beer (when you see all of the different styles in this glossary, you won’t be surprised at that number). The Pharaohs of Egypt paid their workers with jugs of beer (later, the Romans would pay their legions in salt, leaving us with the phrase, “worth his salt” rather than “worth his beer”) (source).

Beer is the third most-frequently-consumed beverage in the world, after water and tea. For those of you who have never been exactly clear on the difference between all the beer types—ale, pale ale, bock, pilsner, and lager (only that you’re happy to drink them all)—check out our Beer Glossary, a tutorial in the types of beer.
 
THE IPA STYLE DEVELOPS

The pale ales of the early 18th century were lightly hopped, but by the mid-18th century they evolved; most were manufactured with coke-fired malt, which produced an even paler ale via less smoking and roasting of barley in the malting process.

In the 19th century, the British living in the Indian Empire drank ale from England, largely because the Indian water supply had microbes that caused digestive problems to humans not raised on it.

But not all beer could hold up on the long journey in a hot ship’s hold. IPA had the level of alcohol (7%-8%) and hops (which act as a preservative) to withstand the voyage of up to six months. (Today, of course, transportation problems have been solved and there’s plenty of bottled water for travelers in foreign lands.)

Demand for a pale ale that could withstand the voyage and the heat en route to India became known as India Pale Ale.

Developed in England around 1840 for the export market, it later became a popular brew at home.

Originally a very highly alcoholic beer to preserve it at sea, the IPA style has evolved (or devolved, in the case of British IPAs) to 5.5% ABV†), but are still highly hopped.

Double IPAs, also called Imperial IPAs, are a stronger, very hoppy and high-alcohol IPA style; the beers typically have alcohol content above 7.5% A.B.V.

 
IPA IN THE USA

While trending now, IPAs have long been brewed in the U.S.

The big difference in contemporary American IPAs is the hops.

Instead of floral and spicy European hops, American hops, grown in the Pacific Northwest, provide distinctively different flavor notes, such as:

  • Earthy spiciness with citrus, from Willamette hops.
  • Fruit explosion—orange, mango, passion fruit, peach and pineapple, from Citra hops; blueberry, tangerine, peach, pineapple and pine from Mosaic hops.
  • Grapefruit, from Cascade hops, and grapefruit-and-floral, from Centennial hops.
  • Herbaceous, providing notes of pine resin, from Columbus, Tomahawk and Zeus hops.
  • Orange blossoms from Amarillo hops.
  • Pine and citrus, from Chinook hops.
  • Combination: grapefruit, pine, sweet onion and tropical fruit, from Simcoe hops.
  •  
    There are many different hops from which brewers can choose, for not just IPA but all styles of beer.

    In addition to Europe, Australia, New Zealand and other areas grow still more species of hops. Here’s more about them.

     
    AMERICAN IPA STYLES

    Within a category even as narrow as American IPA, different styles can be achieved by using different brewing techniques, particular strains of yeast, varieties of hops, the timing of adding the hops, and adjusting the chemistry of the water, and more.

    Among American IPA brewers, three main styles have evolved. Although the style has become popular in the region, it need not be brewed in that region. Nor must any brewer in a particular region subscribe to a particular style.

  • East Coast IPA, a style favored by some craft brewers, is less hoppy than a West Coast IPA. It has a greater malt presence that balances the intensity of the hops. According to Wikipedia, West Coast breweries tend to use hops from the Pacific Northwest, while East Coast breweries tend to favor spicier European hops and specialty malts.
  • New England India Pale Ale or Northeastern Pale Ale is a style invented in Vermont in the early 2010s. It is characterized by juicy, citrus, and floral flavors, with a more subtle and less piney hop taste than typical IPAs; sometime it’s called Juicy IPA. It also has a hazy appearance, and is sometimes called Hazy IPA.
  • West Coast IPA, a style invented in California,is known for bracing bitterness, intense hop aromas and higher-than-average A.B.V.
  •  
    Why not celebrate National IPA with one of each, plus an English IPA to honor where they all began.

    ________________

    *For hop enthusiasts: American hops include, among others, Amarillo, Cascade, Centennial, Chinook, Citra, Columbus, Neomexicanus, Nugget, Simcoe, Tomahawk, Warrior. New varieties are always under development.

    †A.B.V. is Alcohol By Volume, the percentage of alcohol in a product—beer, liqueur, spirits, etc. You double the A.B.V. to get the proof. For example, a 5% A.B.V. beer is 10 proof.
