  • Statement of Process-Word Problem...

    Hello ProBrewers,
    I'm having a real mental block:
    I'm submitting a SOP to the TTB, PDQ! Okay, here's the problem:
    the flavoring I'm adding to my finished beer has an alcohol percent of 32.36 by weight. I'm adding 130 ounces to 310 gallons finished beer. Beer has a pre-addition alcohol percent of 5.5 by weight.
    How much alcohol am I adding with the addition of the flavoring?


    Thanks for any insight,
    Prost!

    If you convert gallons to ounces, multiply ounces by alcohol volumes, add together and divide by total ounces, the average goes up to 5.6% alcohol. Does that sound right?

      That sounds and looks right. The logic holds for me.
      Thanks a ton.

        Here's your mixing equation:
        Aa+Bb=Cc (the most important equation I learned at Seibel!)

        128 oz in a gallon

        (130 oz)(32.36) + (( 310 gal. X 128 oz) ( 5.5) ) =((310X128)+130)) (c)
        solve for c

        4206.8+218240=39810 (c)
        222446.8=39810 (c)
        c=5.587

        So, very little increase, but the ttb has to know. Had the same issue with my Cherry wheat. They should accept that number.

        cheers
