    freezing point of beer

    HI All:

    Does anyone have the formula for calculation of the freezing point of beer handy??

    Thanks

    Hi Fred,

    Here is a link to an article from the Department of Food Science and Technology at UC Davis. The topic of the article is cold conditioning.

    http://www.asbcnet.org/journal/pdfs/2004/0223-02R.pdf

    They provide the following formula:

    The freezing point of a beer is given as Freezing point
    (C) = 0.42 A + 0.04 E + 0.2 in which A is the percent of
    alcohol content by weight and E is the original gravity of the wort
    (3). On this basis, each 1% increase in alcohol content lowers the
    freezing point by 0.42C and each increase in gravity of 1Plato
    (P) raises it by 0.04C. Thus, no beer will freeze at 1C, and
    products at higher alcohol concentrations (including high-gravity
    brews prior to dilution) will withstand even lower temperatures.


    Hope this helps,

    Jim
