    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 0.42°C and each increase in gravity of 1°Plato
    (P) raises it by 0.04°C. Thus, no beer will freeze at –1°C, and
    products at higher alcohol concentrations (including high-gravity
    brews prior to dilution) will withstand even lower temperatures.


    Hope this helps,

    Jim
