American IPA did not begin with the hop-forward releases of the last twenty years, and it did not begin in the 1990s. The beer most writers accept as the starting point is Anchor Liberty Ale, first brewed at Anchor Brewing in San Francisco on 18 April 1975, which took an English pale ale and pushed American hops to the front of it. Everything after that, from the resinous and bone-dry West Coast versions to the soft, cloudy ones now pouring across British Columbia, is a response to that decision, and the useful way to read the style is as a record of what American hops made possible once brewers stopped treating bitterness as the only thing worth chasing.

The Beer That Came First
Liberty Ale is worth naming precisely because the exact date survives: 18 April 1975, a bottling that put a heavily hopped, dry-hopped pale ale in front of a public that had no category for it. One caveat belongs in the same sentence as the claim, since the recipe behind the bottle sold under that name today dates to a revision in 1983, which means the first modern American IPA and the beer you can buy under that label are not literally the same product. That is a footnote rather than a contradiction, and it is a better answer than the one that hands the origin to a brewery that opened a decade later.
The other name that belongs in the origin conversation is Bert Grant, the Scottish-born brewer who settled in Washington's Yakima Valley and is usually given credit for the first modern beer actually labelled an India Pale Ale. The distinction matters more than it sounds, because the words India pale ale had drifted in and out of British use for a century, and the choice to put them on an American label is what made the name available to everyone who came after. Anchor supplied the beer that showed what the country's hops could do, and Grant supplied the name the industry then ran with.
What Vinnie Cilurzo Actually Brewed
Crediting American IPA itself to Vinnie Cilurzo gets the timeline backwards by two decades. What Cilurzo brewed at Blind Pig Brewing in Tempe, Arizona, in June 1994 was the first Double IPA, a beer called Inaugural Ale that he made for the Great American Beer Festival, and he later built Pliny the Elder at Russian River into the most famous example of that stronger category. The double, or imperial, IPA is genuinely important to this story, because it gave brewers a template in which extra grain carried extra hops without the beer thinning out into something bitter and hollow, and that template is the reason hop bitterness could keep climbing through the 2000s. It is still a sequel to American IPA rather than its origin.
Why BridgePort Is Not The Oldest
BridgePort built a wide following in Portland on a hoppy pale ale and is a fair answer to the question of who carried the style into distribution, but it is not the answer to who brewed it first, and a milestone list that starts there skips the whole of the 1970s and most of the 1980s. Anchor was brewing Liberty Ale years before the Pacific Northwest breweries that now dominate these accounts had opened their doors. Settle those two facts and the rest of the timeline falls into place: a California origin, a Washington hop supply, a national escalation in bitterness, and then the hazy turn that split the style into two things that share a name.
Four Eras With Something In The Glass
| Period | What changed in the kettle | What you taste |
|---|---|---|
| 1975 through the 1980s | An English pale ale pushed harder with the first modern American aroma hops | Grapefruit and pine over a dry, biscuity base |
| The 1990s | More bittering hops, aggressive dry hopping, clean American yeast | Resin and citrus with a firm, drying finish |
| The 2000s | Extra grain used to carry a bigger hop load, the double IPA template | Marmalade and tropical fruit at 7 to 10 per cent |
| The 2010s onward | Whirlpool and late hopping, oats and wheat in the grist, yeast chosen for its esters | Soft, low-bitterness, cloudy and juice-forward |
Each of those shifts was a reaction to the one before it. The 1990s made bitterness the scoreboard, the 2000s made strength the scoreboard, and the 2010s gave the whole competition up and went after aroma and mouthfeel instead, which is why a modern tap list can carry two beers both called IPA and expect you to know which family each one belongs to before you order.
What The Style Is Supposed To Smell Like
The descriptor list for the modern version reads like fruit and forest rather than anything else: grapefruit pith and zest, pine resin, mango, apricot, passionfruit, peach, lemon oil, sometimes a herbal or green note from the older American varieties, and clean bitterness sitting behind all of it. Where a hop does come across as vegetal or dank, that is one characteristic among many and not the target of the exercise, so a tasting note that names the least pleasant thing one person noticed has stopped describing beer and started repeating a joke.
Bitterness and aroma are separate axes, and mixing them up is the most common error in how this style gets discussed. A cloudy New England IPA can smell enormous while sitting at a bitterness most drinkers would call moderate, and an older West Coast example can be far less aromatic while leaving a much drier finish. The grist matters here too, because American IPAs generally keep crystal malt low, which is why the good ones finish dry, and a beer that tastes of caramel underneath the hops has drifted into the amber and red ales sitting next to it on the list.
How The Hops Made The Style
American aroma varieties are the reason the style exists in the form it does. Cascade, the hop that started the modern American aroma group, gives grapefruit and a soft floral note, and Centennial sharpened that toward lemon. Later selections out of Washington's Yakima Valley, Simcoe, Citra and Mosaic among them, moved the range into pine, lychee, mango and blue fruit, so a brewer writing a hop schedule today is working with a palette that did not exist when Liberty Ale was first boiled. Yeast has travelled just as far. A clean American ale strain used to be chosen precisely because it added nothing, while several of the strains behind the hazy era are chosen because they throw tropical esters of their own, and because hops added while fermentation is still running react with living yeast to create aroma compounds that were never in the cone.
How Big The Style Actually Is
Sooner or later an article about American IPA wants a market-share number, and that is exactly where you should slow down. Beer sales on this continent are measured by volume and by brewery rather than by style, so a precise percentage for IPA's slice of craft sales is not a figure you can go and check, it is a figure you should ask to see sourced, and the absence of a source is the answer. What can be said without a number is enough: IPA is the style most new breweries here lead with, it decides what a tap list looks like from Vancouver to Vermont, and every other style on the menu is now defined by how far it sits from an IPA.
The British Columbia End Of The Line
British Columbia never had to receive this style at a distance. The Yakima Valley, where most American hops are grown, sits a few hours' drive south of the Lower Mainland, so BC breweries have bought from the same region that supplied the hops behind the classic West Coast IPA. The result is a provincial scene where the hoppiest beer on almost every tap list is built on the American template rather than the English one, and where a drinker working through a hazy pale ale in Langley and a resinous IPA on Vancouver Island is tasting two ends of the same family tree rather than two competing styles.
Frequently Asked Questions
What is the oldest American IPA?
The answer most beer writers accept is Anchor Liberty Ale, first brewed on 18 April 1975, with the caveat that the recipe behind today's bottle dates to a 1983 revision. If the question is instead who first put the words India Pale Ale on an American label, credit usually goes to Bert Grant in Washington's Yakima Valley. Those are two different milestones, and blurring them is the reason several breweries can each make a defensible-sounding claim to being first.
Did Vinnie Cilurzo invent the American IPA?
No, and the confusion is understandable because his contribution is large. Cilurzo brewed the first Double IPA, called Inaugural Ale, at Blind Pig Brewing in Tempe, Arizona, in June 1994, and later made Pliny the Elder at Russian River the best-known example of that stronger style. The double IPA is what allowed hop rates and alcohol to keep rising after the mid-1990s, which makes it the second half of this story rather than the first sentence of it.
When did IPA become popular in the United States?
Brewers were making hoppy pale ales from the mid-1970s, but the style moved from a specialist's choice to a default through the 1990s and then the 2000s, when an informal competition over bitterness pushed hop rates and strength upward year after year. By the time the cloudy versions arrived, IPA had stopped being a category for people who liked bitter beer and become the category, which is why a brewery whose flagship is something else is now the exception rather than the norm.
What is the difference between an American IPA and an English IPA?
American versions use American and New World hops, which read as citrus, pine and tropical fruit, along with a yeast chosen to stay out of the way, while English versions use earthy, herbal and floral varieties with a yeast that leaves light fruit behind. The malt differs too, since an English IPA keeps biscuit and a little caramel and often a soft, low carbonation, and an American one stays pale, dry and highly carbonated so the hops arrive cleanly. Strength overlaps between them, so the difference is character rather than numbers.
Which hops should I look for on a label?
Cascade and Centennial are the classics and will taste of grapefruit and lemon. Simcoe brings pine, Citra brings lychee and citrus, Mosaic adds blue fruit with a dank edge, and Chinook and Columbus sit at the resinous end of the range. A label that names its varieties is usually a brewery asking you to buy the beer on aroma rather than on bitterness, which is the direction the style has been travelling in for the last decade.
How To Taste The History
The quickest way to hear the whole arc is three glasses poured in order. Find an example of the Liberty Ale family for the origin, a bitter and bone-dry West Coast IPA for the 1990s, and a soft, cloudy double IPA for the current direction, then drink oldest to newest without switching back and forth. The differences are not subtleties of degree, since the first tastes like a pale ale with more hops in it, the second like a resinous bitter, and the third like fruit with a whisper of bitterness at the end. One honest warning attached to that exercise: brewery ownership, distribution and taproom status change quickly in this country, so treat any specific name as something to look for on a shelf rather than something guaranteed to be there.
