Climate breakdown is already changing the taste and quality of beer, scientists have warned. From a report: The quantity and quality of hops, a key ingredient in most beers, is being affected by global heating, according to a study. As a result, beer may become more expensive and manufacturers will have to adapt their brewing methods. Researchers forecast that hop yields in European growing regions will fall by 4-18% by 2050 if farmers do not adapt to hotter and drier weather, while the content of alpha acids in the hops, which gives beers their distinctive taste and smell, will fall by 20-31%.

"Beer drinkers will definitely see the climate change, either in the price tag or the quality," said Miroslav Trnka, a scientist at the Global Change Research Institute of the Czech Academy of Sciences and co-author of the study, published in the journal Nature Communications. "That seems to be inevitable from our data." Beer, the third-most popular drink in the world after water and tea, is made by fermenting malted grains like barley with yeast. It is usually flavoured with aromatic hops grown mostly in the middle latitudes that are sensitive to changes in light, heat and water.
Climate-induced decline in the quality and quantity of European hops calls for immediate adaptation measures (Nature).

  • It already cost more and taste worse.
    Guess more incentive to stick with the local stuff.
    • Re:

      That's also what happened with chocolate in the US once manufacturers began replacing cocoa butter with PGPR. You would assume there'd be some huge backlash over it with people dumping their chocolate into the Boston harbor or something, but nope. People are remarkably accepting of the enshitification of their food. Similarly, I wouldn't be at all surprised if the Europeans get used to flavorless beer; Americans already have.

      • Re:

        You've not had a beer in the US in the last several decades, have you.
        • Re:

          What, has Bud Light improved? I wasn't implying that there's any shortage of independent small batch brews, but rather I was referring to the popularity of type of swill the average Walmart customer throws in their shopping cart.

          • Re:

            I consider those beers to be bulk beers. Ie, the people who buy them at Walmart tend to also be buying a minimum of a 24-can carton.

          • Re:

            I see a lot of microbrews, or attempts at pretending to be microbrews even at the larger chain stores. Generally, people buying Snow or Bud either are buying it in large quantities or it is their preference. However, there are a lot of interesting brews popping up all over the place, and available in a lot of locations.

            Ten years or so, I'd assert that the US was a vast wasteland to be mocked by the world for lack of beer choices. These days, with some pubs having 100+ things on tap, there is something de

            • Re:

              We also have entire stores like Wine & More that are like convenience stores for alcoholics. Thousands of microbrews available, imports and some foreign brews available. Plus snacks and mixers. Sometimes even free shots of bourbon while you are there.
        • Re:

          These days mediocre beer is no longer mandatory for Americans. It's just an option. In inexplicably popular option.

      • What always amazes me with these sorts of claims is that they only ever consider what happens if people keep growing things in the same areas. We know that this is not the case and indeed it is already happening with winemaking. The Romans used to grow grapes in England [wikipedia.org] during the historically warm period when they occupied it and people are now doing it again thanks to global warming.

        Why would this not happen with hops too? As the climate warms the best hop growing locations will move further north. So
      • Re:

        So that is why all US "chocolate" tastes like dried crap...

    • Re:

      I'd just be happy if the bros stopped putting in so many hops until it's undrinkable. They need to do more with quality of hops rather than quantity.

      • Re:

        I like beer to have flavor, but some American craft breweries seem to have the belief that the only flavor worth brewing is bitter.

        I do like hoppy beers, but that's not the only flavor you can have in beer. I was in a brew pub a couple of weeks ago, and they had I think eight different kinds of IPA, a pilsner, and one dark beer, a porter. So, I ordered the porter... and they were out of it.

  • Forget rising temperatures, forget an increase in weird weather, forget droughts. You mess with people's beer and action will be taken.

    • Re:

      I do not really care what it takes as long as the politicians wake up and start to follow through on climate change commitments and policies.

      The UK government seems to be pretending that climate change will fix itself if we stick our fingers in our ears and sing La-La-La. I said as much in my 4th email to my MP in 3 weeks on this topic; the governing Tory party is in complete denial. This, for me, makes them completely unelectable.

    • Re:

      Beer has CO2.

      It's only a matter of time until it is illegal.

      • Re:

        In the future only Guinness will be legal.:)

        "Guinness beer, a dark stout beer, is pressurized with nitrogen gas."

        • Re:

          ...and CO2. If it is fermented it will have CO2 since this is a byproduct of the fermentation process. Guniess, and many UK beers where they hand-pull the pints, has less CO2 but it is not free of it.
      • Re:

        There is always Guinness, which is nitrogen charged.

      • Re:

        Beer CO2 comes from carbohydrates, which are produced from CO2 removed from the atmosphere by plants.

  • Finally something that will motivate conservatives to back solutions!

    • Re:

      We must immediately start pumping out more CO2 to improve the heat tolerance and productivity of those crops!

      • Re:

        Putting some places into a more temperate instead of too cold climate is not magically going to cause better crop yields because the soil just isn't there. Soil isn't just some kinda dirt and it doesn't matter that it was permafrost the past couple hundred years.

          • Re:

            Is that why they raided Ukraine? For their black soil?

            That's an even more outlandish reason than wanting to corner the sunflower oil market, but hey, I've heard worse conspiracies.

      • Re:

        Are you claiming it makes more total viable farm land? That's dubious because some currently viable places will grow too dry. It's robbing Peter to pay Paul.

        Sure, Canada and Russia probably will like warmer weather, but others will get whacked. (Actually Canada may experience more flooding in places not prepared.)

  • Farmers are not stupid. What ever it takes to keep their yields they will do. Beer drinkers are safe.

    • Re:

      Beer took off during the Little Ice Age because grapes wouldn't grow in northern Europe. Beer will continue to grow, but will probably be replaced in places with really good wines that have yet to be created.
    • Re:

      Hahaha, no. The little problem with climate change is that it exceeds the current adaption ability of the human race in basically all aspects. There is no reason to believe this will change anytime soon. (Well, except as a "ignore the problem" "strategy" that makes everything even worse...)

    • Re:

      If everyone drank water, none would be left for the beer.

      • Re:

        That almost sounds like a German proverb...

    • Re:

      Water?! Let's try to remember why we invented beer in the first place. Are you trying to give me cholera?
    • Re:

      Drinking water? Drinking? Fish fuck in that stuff!

  • I never got the appeal of this bland bitter tasting drink. Is it just machismo to pretend to like it?

    No I'm not tea total, a love a good brandy or wine. But beer? Blech.

    • Are you saying that there are people who enjoy tastes you dislike? Shocking.
      • Weed smells like a combination of body odour and boiled cabbage to me. But I guess if you're high you wont be smelling much anyway.

      • Re:

        I'm convinced the only people who like that smell are the ones who have associated it with getting high. I've never done weed and to me it's easily in my top 10 most revolting smells. I'd describe it as smelling like something between a roadkilled skunk and that acrid smell you get when a computer PSU has a capacitor blowout.

    • Painting all beer as 'bland' and 'bitter' while championing wine rather misses the point my friend. Would you accept it if I labeled all wines as sweet hangover creators? Beer runs the gamut as much as wine does. I've lived in the 2nd, 3rd, and 5th States by wine production. There are wineries less than 15 minutes from my house. I've traveled to California, Italy, Argentina, and France and toured their wine regions. Every one of these locations had unique to them wine varieties, flavors, and experiences. Some weren't to my liking, my native State (New York) produces a lot of sweet wine I've largely outgrown, but I've found great wines virtually everywhere I've bothered to look.

      Beer is no different. It can range from pale to stout and everything in between. It includes types (e.g., sours) that don't neatly fall on a taste graph. I don't like them all. You called out bitter, so I'll talk about IPAs, one of my favorites except these days they have been massively overdone, because it's easy to cover up a cheap/bad beer with hops. Still some good ones out there but they're hard to find amongst the bad.

      Regardless, point is, there's a huge range of beer flavors that are neither bland nor bitter. You don't have to like beer but don't assume it's all the same.

      • Whatever flavour a beer has is masked by the hops. It's like some fizzy drinks which just taste of sugar regardless of any underlying flavours.

        • Re:

          If you don't like beer, well, that's fine. Though it probably means you haven't tasted very many given you don't like them. It's kind of weird to make assertions about something you don't drink and has a lot of regional variation.

          There are many and, they taste quite different. There are different varieties of hops which impart different flavours and different brewing and preparation methods also impart wildly different flavours. Mild for example is both heavily roasted and very lightly hopped.

          Unless you liv

        • Re:

          If you're drinking a stout and taste the hops it's a bad stout or you have the most's most unique taste buds. There are also beers that do not use hops at all.

          Like I said, you don't have to like it, not trying a hard sell here, but you would benefit from broadening your horizons a bit.

    • Re:

      The recent popularity of hard seltzers is a testament to the fact that yes, a lot of people don't care much for the taste of beer.

    • Re:

      Are we talking beer or the dishwater that's sold under that name in the US?

    • Re:

      Your head is obviously so far up your culo, all you can taste is your own shit.

    • Re:

      Bland? Sound like you had whatever cheap yellow piss your local city/state serves. I don't judge all of American cuisine by a McDonald's cheeseburger either.

      • Re:

        Guinness and ales tastes even worse. HTH.

    • Re:

      A person who comes home from work and just wants a cheap and effective way to disconnect from stress and simply have some happy feels is not machismo. It's just trying to enjoy life a bit.

    • Re:

      Wine ? Thats even worse it just tastes like mild vinegar
  • Monks have been brewing certain beers in Europe since before the last Warm Period and into the Little Ice Age, theyâ(TM)ve survived through wars, droughts, the Black Death, severe weather. The temperature changing a degree over the next 100 years is minor, there have been bigger fluctuations in the history of eg. Affligem (a beer brewed since 1054).

    The reason costs are driven up in Europe is regulation, pure and simple. The weather has had very minimal effect on global market operations.

    • Re:

      What are you talking about? Everyone agrees any problem in the world today is because of the climate change crisis. Don’t be a climate denier!

    • Re:

      Yeah, I have tasted beer brewed with medieval means. It's one of the "joys" of having an experimental archaeologist as a friend (another one is being used as a mechanical crane operator, ya know, the guys that ran in those huge hamster wheels...).

      You know why they drank beer? Because the water was even dirtier and more likely to give you the shits. It was absolutely, positively and CERTAINLY not for the taste.

  • 1. Redefine "middle latitudes" to some number closer to 90.
    2. Grow hops mostly in the newly-defined "middle latitudes."
    3. ???
    4. PROFIT!!!!

    The joke is, sadly, that this is not a joke.

      • Re:

        Didn't the frothy mouth already give it away?

  • Julian Simon says costs will continue to drop, and quality, including taste, will continue to increase. [juliansimon.com]

    Sans government interference.

    This isn't really disagreeing with the scientists prognosticating physical problems, only that, in spite of them, clever humans will continue to adapt faster than problems become problems, often using such science to help adapt. As long as some politician doesn't decide beer needs command and control and rationing.

    • Re:

      clever humans will continue to adapt faster than problems become problems

      I hope someone else handles your investments for you, because past performance is no guarantee of future results!

    • Re:

      Policy makers have been commanding and controlling beer production since the middle ages. Look up "Reinheitsgebot" and "Maerzenbier" for two obvious examples. Rationing happened during WWII, too.
  • For all the snobbery in alcohol appreciation (and I do love scotch), the price going up and the quality going down isn't going to make people walk away. Their tastes will adjust.

    • Re:

      You sound like someone who drinks beer to fit in rather than drinking beer for the enjoyment and the taste.

      • Re:

        What a strange conclusion. No idea how you got there.

        • Re:

          Simple, people don't adjust their tastes of something they really appreciate because of price. They do so for things they don't appreciate. If you're a person who thinks beer is beer then your taste will adjust. If you're a person who appreciates the intricacies and really enjoys the one specific flavour and style of that special DIPA made by a specific Estonian craft brewery you will stick with the price rise, but not the change in taste. The change in taste will make you walk away.

  • I don't know if I can take any more bad news.

    • Re:

      What's the difference?

  • About a thousand years ago during the Medieval Warm Period, the Britons were growing grapes and making them into wine.
    This was about the time the Vikings colonized Greenland (and Iceland) and found Vinland (Nova Scotia).
    Then came the little ice age and Britons turned to beer (cause the grapes wouldn't grow anymore), Vikings abandoned Nova Scotia and Greenland (too cold).
    And the Anasazi disappeared (I assume these little climate change were all across the northern hemisphere, not just western europe), pre
  • Enough is enough! So far, I didn't care and tossed the styrofoam containers for my grease burgers into the natural reserve, but if that's the price, it's time that we pick up recycling!

  • We've had good beer in the US for a long time and it's not going anywhere. I suppose my EU friends can import some fine ale from the US.

  • If beer is affected, now I am a true believer. We must do something, and we must do it now!
  • These dumbass articles are good for a giggle, but farmers are keen to grow crops where they'll grow. So the hop farms will move further North. In Europe hops are grown as far south as Spain (which is quite toasty) and as far North as Poland. Perhaps the Spanish hop farms will shut down and Denmark will grow them.

  • One has to suspect poor quality due to economic reasons since they lost all that cheap Russian gas....
  • Crap, *now* we have to fix it...
