  • Posted in thread: New Years Resolution - win HB comp on 01-09-2014 at 06:00 PM
    Good advice here. My resolution is just to enter some comps so I'm in the same boat. I just
    started reading Brewing Better Beer and it's got some really good things to think about and
    apply, I'm not e...

  • Posted in thread: "Isomerization" in Hops??? on 01-07-2014 at 02:35 AM
    It's the isomerization that creates the bitterness-- converting one isomer of a hop acid into
    another. For a given amount of hop acids in the boil, the percentage that get isomerized is
    your utilizati...

  • Posted in thread: Calculate OG from ABV and Attenuation? on 01-07-2014 at 02:20 AM
    No, what I did was put 25 grams of sugar in a glass measuring cup and topped it up to the 250
    ml mark with water. Then I weighed the container and took the specific gravity of the solution.
    Now since ...

    A miracleIt is and it is but the 'points per pound' mentality is so engrained in home brewing
    that I don't think anything will ever get them to change. I guess I have my work cut out for me
    to convice...

    Also, don't think that you have to brew only all-grain to win competitions. I've done it with
    extract and specialty grains.The advice about adherance to style specifications is right on.
    This does not...

  • Posted in thread: Why not wash and repitch dry yeasts? on 01-03-2014 at 01:36 PM
    I have just poured wort onto the yeast cake of a prior fermentation with good results, though I
    would be wary of doing it more than once. I've seen fermentation activity start within minutes
    this way.

  • Posted in thread: Calculate OG from ABV and Attenuation? on 01-03-2014 at 01:31 PM
    All gravities here are in P.Which brings up the question I've had for a while, which is, what
    would it take to get the homebrewing community at large to start thinking in metric terms?I
    posed my orig...

  • Posted in thread: Calculate OG from ABV and Attenuation? on 01-03-2014 at 01:26 PM
    By FAR, the easiest formula is to just set your OG the same as the ABV you desire. For
    example[*]for a 5.5% beer, OG = 1.055 [*]for a 8.0% beer, OG = 1.080This always works assuming
    attenuation of 76%...

  • Posted in thread: Calculate OG from ABV and Attenuation? on 01-03-2014 at 01:25 PM
    Yes, you need to expand the OG*(1-A) term. Doing it in my head, it looks like you get: OG=
    (7.46*ABV)/AYep, that works thank you!

  • Posted in thread: Calculate OG from ABV and Attenuation? on 01-01-2014 at 11:14 PM
    I am not sure if this is possible to do with algebra but here goes:Coopers says to determine
    ABV use the formula ABV = (OG-FG)/7.46Is there a way to use this to determine the OG required
    for a desired...
