    err..not strictly soft drink. The other byproduct of the reaction demonstrated here will be alcohol. Though after just one day the alcohol content will be low.

    As a rough guide:

    Decrease in total weight of sugar (grams) x 2.1075
     —  —  —  —  —  —  —  —  —  —  —  —  —  —  —  —  —  —  —  —  —  —  —  —  —  —  —  —  — -
    Days of fermentation

    This is also useful:

    Alcohol yield co-efficient = % alcohol

    Initial % sugar - final % sugar
