“Frost brewed” beer isn’t anything special, that’s how beer is made

Posted on June 11th, 2009

Almost every macro-brewery has at one point or another laid claim to being the coldest brew at the store or on tap. We’ve all seen in countless TV commercials and Super Bowl spots where advertisers victoriously proclaim that their beer is always Ice Brewed or Cold Brewed or Frost Brewed or Glacier Brewed or some-other-cold-sounding-word brewed.

Coors Light with their recent “Our beer tastes like licking the Rockies” advertising shtick, is particularly guilty of this, just take a look at this ad featuring former NFL coach Bill Parcells. (Starts around the :30 mark)

34 degrees sounds pretty cold, right? Pretty impressive maybe? Let’s do some fact checking with John Palmer, author of the book How to Brew, a guide to home brewing. 34 degrees happens to be the exact temperature Palmer recommends for making lager in your kitchen. So way to go MillerCoors, you’ve managed to follow directions from a recipe and do something anyone with an old ice box and a couple of bags of ice can accomplish. Brilliant!

Beer companies are usually selling the message of Ice Cold Beer because they know it appeals to the consumers sense of refreshment. They are also willing to assume that the average American does not know how beer is made, much less what a hop is (a topic for a much larger post down the road).

Beeriety is here to change some of these myths by providing more information about beer, beer culture and homebrewing to the everyday drinker.

    But Miller also puts hops in their beer at THREE DIFFERENT TIMES during brewing! What a completely standard idea!

  • That's a topic for another post!

    Having just sat down at my computer after seeing a Coors commercial and deciding once and for all to figure out what the hell 'frost brewed' means anyway, I'm delighted to see that the fifth google search result turned up this blog.
    Clearly, I did this the long way.
    Good work, Carleton.

    Palmer recommends lagering the beer at 34F. The actual fermentation temperature where the wort is converted to beer would be 48-58F, see Wyeast’s American Lager (2035). Yeast work very slowly at 34F and would never finish a fermentation.

  • No

    34 is too cold

    I beg to differ. Since the brewing process requires a boil, the laws of physics generally prohibit this from happening with frost or ice. Beer is brewed by applying heat, not cold.
