Alright folks, pull up a stool! As your Head Brewer and a certified BJCP expert, I’m always fascinated by how beer styles evolve. Few styles demonstrate this better than the American IPA. Today, let’s crack open the BJCP Guidelines and dive into the fascinating differences between the 2015 and 2021 iterations of the American IPA, and what those changes tell us about the ever-shifting landscape of craft beer.
Back in 2015, the American IPA was defined by its aggressive hop character, showcasing a prominent bitterness alongside citrus, floral, piney, resinous, and sometimes even dank aromas and flavors. The malt backbone was often quite present, sometimes featuring caramel or crystal malts, providing a medium body and a sweetness that helped balance the significant hop bitterness, typically ranging from 40-70 IBUs. Clarity was paramount – a brilliant, clear beer was the expectation, reflecting the West Coast IPA dominance of the era. It was a beer about impact, a sharp, bold statement.
But beer never stands still, and brewers and drinkers were already pushing boundaries. The craft scene was buzzing with new hop varietals and techniques, leading to IPAs that were less about raw bitterness and more about complex, juicy aroma and flavor. This shift started blurring the lines, challenging the traditional definition.
Fast forward to 2021, and the BJCP guidelines reflect this evolution beautifully. While the American IPA still celebrates hop-forwardness, the focus has broadened significantly. Bitterness is still there, but often perceived as softer, cleaner, and more balanced, with the IBU range adjusting slightly to 40-70 IBUs, but with a greater emphasis on *perceived* bitterness rather than just numerical values. The hop character has expanded to include a wider array of tropical fruit, stone fruit, and berry notes alongside the classic citrus, pine, and resin. Malt character is typically cleaner, drier, and lighter-bodied, acting more as a canvas for the hops rather than a balancing act of sweetness. The goal is to allow the full spectrum of hop expression to shine through. While still generally clear, the guidelines acknowledge that some modern interpretations might exhibit a slight haze, though never to the turbid levels of its newly recognized sibling style…
…the Hazy IPA. This is perhaps the most significant differentiator: the 2021 guidelines introduced a separate category for Hazy IPA (or New England IPA). This separation allowed the ‘American IPA’ category to re-center itself. The 2021 American IPA is effectively the *clear* IPA that has absorbed some of the modern hop aromatics (tropical, fruity) but maintains a drier, cleaner finish and a generally clear appearance. Gone is the expectation for significant caramel malt character; brewers are now often using cleaner base malts and sometimes a touch of wheat or oats for body, but without promoting haze. The drier finish elevates the hop expression without residual sweetness masking it.
The evolution from 2015 to 2021 for American IPA highlights the style’s incredible adaptability. It moved from a powerhouse of bitterness and balancing malt to a refined showcase of hop aromatics and flavors, supported by a clean, dry canvas. The BJCP didn’t invent these changes; they documented what brewers were already doing. As brewers, this gives us a fantastic roadmap for crafting diverse IPAs – whether we’re aiming for a classic bitter bomb or a clean, fruit-forward hop explosion. Cheers to evolution!
