West Coast IPA (India Pale Ale) beers have emerged as a prominent style within the craft beer movement, captivating beer enthusiasts with their distinct characteristics. Renowned for their bold hop presence, West Coast IPAs strike a delicate balance between pronounced bitterness and vibrant citrusy flavours. In this article, we will delve into the origins of West Coast IPA, explore the brewing techniques that contribute to its unique profile, examine the key elements of bitterness and citrusy goodness, and highlight some notable examples of this beloved beer style.
The Origins of West Coast IPA
Historical Background
The roots of IPA can be traced back to the 18th century when British brewers began developing a hopped beer style with higher alcohol content and increased hop levels to withstand long sea voyages to India. Fast forward to the modern craft beer era, and we witness the evolution of IPA into different variations, including the West Coast IPA.
Brewing Revolution on the West Coast
The West Coast of the United States played a pivotal role in shaping the West Coast IPA style. Breweries such as Sierra Nevada Brewing Company, Anchor Brewing Company, and Stone Brewing Co. were instrumental in introducing the world to the hop-forward and bold flavours that characterise West Coast IPAs. They embraced the use of local hop varieties and pushed the boundaries of what an IPA could be.
Brewing Techniques for West Coast IPA
Malt Bill
The malt bill of a West Coast IPA typically consists of pale malts, such as American 2-Row or British Maris Otter, which provide a clean and neutral base for the hop flavours to shine. Additionally, small amounts of speciality malts, such as crystal or caramel malts, may be used to add some complexity and colour to the beer.
Hop Selection
One of the defining features of West Coast IPAs is the bold and vibrant hop character. West Coast brewers often opt for hop varieties with high alpha acids, such as Cascade, Centennial, Simcoe, Amarillo, and Citra. These hops contribute intense bitterness, as well as distinctive citrus, floral, and pine aromas.
Hop Additions
West Coast IPA brewing involves multiple hop additions during the brewing process. Bittering hops are added early in the boil to extract alpha acids and create a solid foundation of bitterness. Flavour hops are added towards the end of the boil, contributing additional hop character and complexity. Finally, aroma hops, often added during whirlpool or in the fermenter, lend their enticing aromas to the finished beer.
Dry Hopping
Dry hopping is a technique commonly used in West Coast IPAs to enhance the beer’s aroma without adding significant bitterness. This involves adding hops directly to the fermentation vessel, allowing the hops’ essential oils to infuse the beer with intense citrusy and resinous aromas.
Bitterness in West Coast IPA
Understanding IBUs (International Bitterness Units)
IBUs measure the bitterness of beer, with higher values indicating greater bitterness. West Coast IPAs typically have higher IBU ranges compared to other beer styles, ranging from 40 to 100 IBUs or even higher. However, it is essential to note that the perception of bitterness is also influenced by other factors, such as malt sweetness and hop flavour.
Hoppy Bitterness vs. Harsh Bitterness
The bitterness in West Coast IPAs comes primarily from the hops used during brewing. The hop-derived bitterness is typically clean, crisp, and pleasant, providing a refreshing contrast to the beer’s malt sweetness. It is crucial to distinguish this hoppy bitterness from the harsh bitterness that can arise from over-extraction of tannins or improper brewing techniques.
Balancing Bitterness with Malt
To achieve a well-balanced West Coast IPA, brewers carefully calibrate the amount of malt sweetness to counterbalance the hop bitterness. The pale malts used in the malt bill provide a light and slightly sweet backbone that complements and supports the hop flavours, resulting in a harmonious interplay between bitterness and maltiness.
Citrusy Goodness in West Coast IPA
Hop Aromas and Flavours
The hallmark of a West Coast IPA is its vibrant citrusy character. The hop varieties used in these beers impart a range of citrus aromas and flavours, including grapefruit, orange, lemon, and tropical fruit notes. Citrus-forward hops like Cascade, Amarillo, and Citra are often employed to enhance these desirable characteristics.
Grapefruit, Orange, and Tropical Notes
The choice of specific hop varieties and brewing techniques greatly influences the citrusy profile of West Coast IPAs. Grapefruit notes often stem from hops like Cascade, while orange and tropical fruit flavours can be attributed to hops like Amarillo and Citra. The combination of these flavours creates a refreshing and zesty experience for the palate.
Citrusy Hops and Food Pairings
The citrusy goodness of West Coast IPAs opens up exciting possibilities for food pairings. The bright and zesty hop flavours complement a wide range of dishes, including spicy cuisine, grilled seafood, citrus-infused salads, and even tangy desserts like lemon bars. The beer’s citrus notes can provide a delightful contrast or harmony with various flavours in food.
