The strong hoppy red keeps losing tap handles because it has to solve two problems at once, and only one of them is chemical. The beer carries roughly twice the residual sweetness of a red IPA while being bittered harder than any amber ale, so the balance has to be rebuilt from scratch every time the recipe gets bigger and every time the glass gets warmer. Then it has to be sold as a big beer in a market where eight percent stopped being big, and where the two words that used to signal size, imperial and double, now belong to categories with shelves of their own. The naming has not helped either, since the same family of beer has been sold as a red IPA, a double red, an imperial red and a strong amber without anybody agreeing what separates them.

What To Know Before You Buy A Big Red
- Read the two style guides side by side, because the Brewers Association and the Beer Judge Certification Program do not agree on where an imperial red ends and a red IPA starts.
- Expect the finish to matter more than the alcohol figure, since a big red that holds its dryness to the bottom of the glass is working and one that turns sticky in the second third is not.
- Set the bitterness by taste rather than by the top of a published range, because a dense wort uses a lower share of the hops you add than a pale ale does.
- Serve it cooler than a cellar ale and drink it young, because the volatile part of the hop charge leaves the glass before the malt does.
The Arithmetic That Makes The Beer Hard To Get Right
Bitterness and sweetness do not scale together, and that single fact is most of the difficulty. The Brewers Association gives an imperial red ale a band of 8 to 10.6 percent alcohol bittered at 55 to 85 IBU, and gives the rung underneath it, which that body calls a double hoppy red ale, 6.1 to 7.9 percent at 45 to 80 IBU. Read the bitterness column across those two rows and notice how little it moves while the grain bill nearly doubles. A brewer who cannot lift the bitterness in proportion to the malt ends up with a bigger beer that tastes sweeter at a higher IBU figure than the smaller one tastes at a lower number, which is the opposite of what the word imperial promises.
The reason the hops cannot keep up is that a dense wort fights back. Isomerization of alpha acids is less efficient as gravity rises, so a given weight of hops yields fewer bitterness units per barrel, and the fermentation that follows a high-gravity wort runs harder and longer, which loses more of the bitterness that did get extracted. Jeff Alworth states the comparison plainly: a Scottish ale hopped at a tenth of a pound per barrel gets about 60 percent utilization in Beervana's summary, while an imperial red at super-high gravity and an outrageous hop rate falls below 20 percent. The brewer who answers that by buying more hops is paying more per batch for something other than bitterness as well, because hop plant material arrives with polyphenols that pull protein out of suspension and leave a drying, grippy texture along the sides of the tongue. That texture is not bitterness, and in a beer already loaded with malt it reads as harshness in the finish rather than as balance.
Two Names And No Agreement About The Line
What actually separates an imperial red from a red IPA is that the two names were earned in different places and never reconciled. Red IPA exists in the Beer Judge Certification Program guidelines as a specialty IPA sub-category, and what makes it an IPA is the finish rather than the colour: the entry gives an original gravity of 1.056 to 1.070 falling to 1.008 to 1.016, and says the beer keeps the dryish finish and lean body that make IPAs drinkable while adding caramel, toffee or dark fruit underneath the hops. Anything stronger than that has no category of its own in the same document, so the guidelines push it into American strong ale, a deliberately broad catch-all whose description names modern double, imperial red and amber ales as its usual contents and allows a finishing gravity of 1.014 to 1.024.
Put the two figures side by side and the difference stops being about hops at all. The strong version is permitted to leave behind close to twice the extract of a red IPA while the bittering range barely climbs, so one name is defined by where the gravity ends and the other by where it starts. A red IPA has to finish dry to hold the label, and an imperial red is defined as being big enough that nobody has to say how it finishes, which is the whole distinction and the reason the same beer turns up on lists under both words.
| Name | Who defines it | Bitterness | Alcohol |
|---|---|---|---|
| Red IPA | BJCP, as a specialty IPA | 40 to 70 IBU | 5.5 to 7.5 percent |
| Double hoppy red ale | Brewers Association | 45 to 80 IBU | 6.1 to 7.9 percent |
| Imperial red ale | Brewers Association | 55 to 85 IBU | 8 to 10.6 percent |
| American strong ale | BJCP, as a catch-all | 50 to 100 IBU | 6.3 to 10 percent |
The two bodies are not even measuring the same thing, since one writes a category around dryness and the other writes a ladder around strength, and the strong red sits in the gap. A recipe built to the top of the bitterness band and the bottom of the gravity band satisfies one and fails the other, which is why a beer can medal in a strong red category and still be described by the person drinking it as too sweet.
How The Word Imperial Built The Category And Then Emptied It
Imperial is a borrowed word with a specific history and no built-in ceiling. Its use in beer comes from the Russian imperial stout brewed in London during the 1700s at the brewery of Henry Thrale, made for the court of Catherine the Great at something like ten percent alcohol, and the style came back into American attention during the 1980s through Samuel Smith's Imperial Stout from Tadcaster. From there the prefix went onto anything that had been made stronger, and the standard reference lists the order with some amusement: imperial India pale ale first, then imperial brown ale, imperial pilsner, imperial witbier and even imperial mild, a process it calls being imperialized.
That habit is what did the damage, because it converted a name into a size. Once imperial meant only stronger than the ordinary version of something, it stopped carrying any information about malt, hops or finish, and the strong red that had borrowed the word found itself labelled by volume rather than by character. The beers the same habit produced around it, imperial stouts pushing eleven percent and double IPAs at nine, then reset what strong tasted like, so a red ale at eight percent no longer sounded like an exception to anything. The category stopped expanding upward for a boring reason rather than a tasteful one: the hop bills needed to keep those beers balanced are where the practical ceiling sits, and a brewery that has to double its hop charge to hold a line at 1.090 has found a cost problem disguised as a style.
The origin stories are equally unhelpful for anybody looking for a definition, because the strong red was never designed. The judging guidelines record that Stone Arrogant Bastard came out of a pale ale batch mistakenly brewed with excess ingredients and may have been the prototype for the imperial amber and red ales, and that Great Lakes first brewed Nosferatu in the early 1990s as a stock ale before the same beer appeared on its own label as an imperial red. A category assembled after the fact from strong beers that had no name is not going to produce a settled description of what it should taste like.
The Problem Shows Up In The Second Half Of The Glass
A strong red that tastes correct at the first sip can be unpleasant by the third, and the reason is that the two halves of the balance respond to warmth in opposite directions. The hop aroma that stops the finish reading sweet is made of volatile oils that leave the liquid as the glass comes up to room temperature, bitterness itself dulls slightly as the ethanol warmth spreads, and that warmth registers on the palate as sweetness rather than as heat. What is left in a glass that has stood for ten minutes is the residual gravity with nothing working against it. If the beer was built on the assumption that hops would cancel that extract out, the cancellation has quietly stopped while you were talking.
The failure runs in both directions, which is what makes the style difficult rather than merely unfashionable. Under-support the bitterness with malt and the beer is all edge, because hop bitterness needs something underneath it or it lands as a dry, lingering harshness rather than a clean bitter close. Over-support it and the same beer that seemed well made cold turns sticky as it warms. Adding body is the tempting wrong answer: dextrin and crystal malts will lift the finishing gravity and thicken the texture, and this beer already carries more unfermented extract than anything else in its colour range, so the extra weight simply arrives earlier and stays longer. The version that holds together to the bottom of the glass is drier than the stereotype suggests, takes its colour from dark malt rather than from what the yeast left behind, and is served cool enough that the volatile part of the hop charge is still present in the second third.
What A Brewer Does About It
- Mash on the cooler side of the saccharification range and let specialty malt supply the flavour, because a hot rest leaves unfermentable material behind that will still be in the glass after the bitterness has faded.
- Keep the crystal malt doing a colour job rather than a body job, and remember that the darker grist also pulls mash pH down, which changes how clean the bitterness lands in the finish.
- Set bitterness by taste rather than by the top of a published range, since utilization in a wort starting above 1.080 can be less than half of what the same hop schedule returns in a pale ale.
- Treat water as the last adjustment rather than the first, because a sulphate-heavy profile sharpens a bitterness this beer already has in quantity, while chloride rounds the malt without adding any sugar to it.
- Use a clean, alcohol-tolerant yeast and let the fermentation finish, since a lagging ferment leaves real sugar in a beer that is already carrying more extract than its name implies.
- Pour it cooler than a cellar ale and sell it young, because the hop charge that makes the style worth brewing is the first thing in the glass to disappear.
Two BC Beers That Show How Far The Names Have Drifted
The clearest local evidence that these two labels have stopped describing a beer is what has happened to them on a BC release list. Cannery Brewing in Penticton put out a limited Dry Hopped Imperial Red listed at 7.5 percent and 60 IBU, described by the brewery as a malt-forward lager dry-hopped with Simcoe, Mosaic, Centennial and Chinook. It is imperial by name only, since it sits under the eight percent floor the Brewers Association sets for the style, and it is not an ale at all, which is a naming outcome nobody would have accepted when those categories were being written.
The other end of the ladder has slid the same distance in the opposite direction. Cutwater Brewing and Lounge in Lake Country lists a red IPA called The Highlander at 5 percent and 59 IBU, bittered like an India pale ale and brewed at the strength of an ordinary amber, below the floor of the red IPA category entirely. Both beers appeared in the BC Ale Trail roundup of summer 2026 releases, and both are worth drinking for what they actually are. Neither one tells you anything about a style, which is the point: on this side of the country the words red and imperial describe colour and volume the way a menu describes lunch, and a reader who treats them as specifications will keep being disappointed by the gap between the name and the beer.
Frequently Asked Questions
Does an imperial red ale get better with age?
It improves in the direction you will like less. The malt and the alcohol will hold and can soften, but the bitterness and aroma that make this beer balanced rather than heavy are the same compounds that break down in storage, so a year-old example is a sweeter, flatter version of the beer somebody chose to brew for its hop side. Cellaring makes sense for a barleywine or a strong Scotch ale, where the flavour is built in the kettle before the yeast arrives, and very little sense for a beer whose whole argument is hops.
Why does my imperial red taste harsh rather than bitter?
Harshness usually comes from the mass of hops needed to reach a target bitterness in a dense wort, because that plant material brings polyphenols with it, and those pull protein out of suspension and leave a drying texture instead of a clean bitter close. The fixes are unglamorous: move more of the charge to the end of the boil or to after fermentation has slowed, keep mash pH in the normal range, and stop treating the top of the published IBU band as an objective.
Is an imperial red just a double IPA with colour in it?
No, and the difference is the malt rather than the strength. A double IPA is bittered higher and finished drier, with a malt bill that is meant to disappear. An imperial red is bittered less than that while carrying more of what the yeast did not eat, which is why the two can share an alcohol figure and feel like different drinks at the end of a long evening. If a big hoppy red is being brewed to a double IPA's bitterness and dryness, it is a brown-tinged double IPA and the name is doing no work.
How strong is the style supposed to be?
The published ranges are wider than the name implies, and the disagreement between the two governing bodies is on the record. The Brewers Association puts an imperial red ale between 8 and 10.6 percent and its double hoppy red rung between 6.1 and 7.9, while the Beer Judge Certification Program has no separate imperial red category and files strong versions of the beer in American strong ale, which runs from 6.3 to 10 percent. Anything inside that overlap is defensible on the label, and the figure that decides whether the beer works is the finishing gravity sitting underneath the alcohol.
The Style Was Never A Recipe, It Was A Ratio
What survives once the names come apart is a ratio and a warning. A hoppy red works when bitterness arrives quickly enough and lasts long enough to cut the extract sitting under it, and it fails when a brewer assumes that the hops paid for at the start of the boil will still be doing that job at the end of the glass. The strong version is not harder to flavour than anything else, it is harder to keep balanced for the twenty minutes a pint takes to warm, which is a manufacturing problem in a market that drinks cold from cans outdoors, and that is the most honest explanation for the empty tap handles. If you want the argument settled in one evening, find a red IPA and something bigger and hoppy in the same colour range, pour both at the same temperature and drink them side by side to the bottom of the glasses. The one that is still interesting in the last third is the one worth the extra money, and after that you will know which of the two names you actually want on your own shopping list.
