The story
The Double IPA — also called Imperial IPA — is a thoroughly American invention. Vinnie Cilurzo is often credited with brewing one of the first at Blind Pig Brewing in Temecula, California in 1994, reportedly adding extra malt and hops partly to cover flaws in a brand-new brewing system. He later created Pliny the Elder at Russian River Brewing around 2000, and that beer became the style’s cult icon, frequently topping “best beer in America” polls.
Through the 2000s, brewers raced each other toward bigger and bolder, with some chasing ever-higher bitterness numbers. Eventually the style matured into something more refined: intense, yes, but drinkable, with the alcohol kept in check.
What it tastes like
A great double IPA is hop-saturated yet surprisingly smooth. The aroma bursts with citrus, pine, tropical fruit, and dank resin. The body is medium and the malt provides a clean, lightly sweet foundation, but the best examples finish drier than you’d expect for the strength. Bitterness is high and the alcohol provides a gentle warmth without tasting hot or boozy. Color sits between gold and light copper.
How it’s made
It’s essentially an IPA recipe scaled up. Brewers use lots of pale malt and often add simple sugar, which boosts alcohol while keeping the body from getting heavy. Hops appear in enormous quantities, often several pounds per barrel, spread across the boil, whirlpool and multiple dry-hop additions. A healthy pitch of clean American yeast is vital to ferment all that sugar cleanly. Hazy double IPAs follow the New England playbook with oats, wheat and lower bitterness.
Fun fact
There’s a ceiling to bitterness. Human taste buds struggle to distinguish much above roughly 100 IBU, and iso-alpha acids have limited solubility in beer. So when a label brags about 1,000 IBUs, that number is largely a calculated figure — your tongue simply can’t tell the difference.
