Help! Global warming is killing Czech beer! / Pomoc! Globalni oteplovani nici ceske pivo!

czech beer google imageA recent study of the Czech Hydrometerological Institute concluded that “even with the modest warming so far experienced, hop yields in the Czech Republic have stagnated and quality declined”. The increasing temperatures (although very suttle) have been taking  the toll on the ‘beer plants’ which in turn could reduce their yield  by a further 7-10%. Perhaps the most worrying is the decline in the quality of the Saaz hops, which produce our good old Czech pilsners. “The “Alpha” acid content – “a major determinant of quality”, according to the team, as it’s the compound that produces a pilsner’s defining bitter taste – is likely to fall a further 13-32% if the predicted warming occurs. The study found that the concentration of these acids has fallen by 0.06% a year since 1954.”

Another researcher from New Zealand National Institue of Water and Atmospheric Research, Jim Salinger, concluded: “It will mean either there will be pubs without beer, or the cost of beer will go up.”

Well good, at least there will be less alcoholics in the world ;0)

CZ: Nedavna studie  hydrometerologickeho ustavu v Praze zverejnila studii o nynejsim stavu naseho chmelu a neni to hezky pohled. Diky oteplovani podnebi (i kdyz se tu bavime o pouhych desetinach stupne) se kvalita ceskeho chmelu totiz zhorsuje. V budoucnosti by se uroda mohla snizit az o 7-10%, kde hopsinky, z kterych se vyrabi svetoznama plzen, maji trpet dokonce i vice. Plzen ma v sobe totiz specifickou kyselinu, ktera muze v hopsinkach v budoucosti klesnout o 13 az 32%. Tato ‘plzenska’ kyselina pry klesla od roku 1954 pouze o 0.06%, takze to by byl obrovsky rozdil.

New Zealandsky vedec Jim Salinger ktery se timto tematem zabyva to shrnul takto: “To znamena ze bud budou hospody bez piva, nebo bude pivo mnohem drazsi”.

A ja rikam jen tak dal, cim min piva, tim min alkoholiku po celem svete ;o)

If you liked this post buy me a coffee! (Suggested:$3 a latte $8 for a pound) Thanks!

    Love the photo!

    Thanks! The Czech-style spa..yeah baby!

    Ahoj Tanja,

    Ok, How about a pint of coffee or tea with a wee bit of Whiskey?

    I located the original article but could only read the abstract. To obtain a copy of the whole article costs $31+. At that price, I can get one cup of coffee/per day for a month.

    The abstract does not convince me that Global Warming is the cause. Wikipedia adds a great deal background information: http://en.wikipedia.org/wiki/Hops All hops and especially the Noble Hops can only be grown in very specific regions. It’s politics! Growing the crop year-after-year in the same area causes a loss of important nutrients. After a few hundred years, the hop crop yields might be expected to drop. Someone wants to move the hop fields.

    Hi Albert,

    I also think that global warming is largely a political issue and some of the data may have been blown out of proportion but there may still be some truth in it..we will find out in 30 years!

    The beer still tastes the same to me. I thought global warming started, when Ice Age ended, guess not. I live east of San Francisco, the average summer temperature is around 90 degrees Fahrenheit. We had the coolest summer in these many years. All I can say is: “Cheers”

    Haha, I am sure Vaclav Klaus would be able to explain all this to you. By the way, I am not sarcastic, he really knows his stuff..

  • Albert October 1, 2009, 2:18 pm

    Ahoj Tanja,

    Global warming is REAL! http://en.wikipedia.org/wiki/Global_warming
    I just doubt that it is responsible for the decline of the quality of Hops.

  • Tanja October 1, 2009, 4:08 pm

    Hi Albert, I know it’s real but it has become a political agenda of many political parties/organizations, so one has to listen to the news about that stuff with a critical ear

    Ahoj Tanja,

    Here is a links to a Wikipedia article about the Český hydrometeorologický ústav (ČHMÚ). http://wapedia.mobi/en/Czech_Hydrometeorological_Institute They study air and water quality, but nothing about soil quality or plant genetics. Without reading the original paper in its entirety, I do not see why Global warming can be argued as causing the of the hop quality problem. Perhaps some the stimulus money can be used to initiate a world wide study of hop quality. All reports should be required to be prepared in OpenSourceDocument format and posted on the internet so that every beer lover can freely read them.

    I agree with Albert in that if you grow the same plant again and again, it will basically deplete the nutrients in the earth. If the global warming is the issue, let’s grow hops in Canada.
    The global warming is a part of “god’s will” and we have no power over it. There was an Ice Age and and
    since USA was not around, there is no one to be blamed.
    Let’s pray for global cooling and cheaper heating oil 🙂

    Global Warming and Climate Change is the biggest environmental issue that we face these days. the long term effects of these environmental changes to a nations economy is quite damaging. there would be a shortage in food supply as well as on water supply too.

  • Olivia Smith April 25, 2010, 11:10 pm

    The effects of Global Warming is getting much stronger these days. We should concentrate more on alternative energy to reduce carbon emissions.
