Mr HAttenuation?

1 year ago | Mr H (Member)

Hi,
May seem like a silly question and there is probably a simple formula, but how to you work out the attenuation of a particular yeast when pitched into your wort?
Say I wanted to to pitch a Ringwood Wyeast with an attenuation rate of 68-72% into a wort of say 1.051, what final gravity could I expect this type of yeast to leave me with? is there an easy way to work this out? Probably the most obvious and simple calculation im missing - but can't get my head around!
Hope your all keeping good and brewing well!
Cheers, H

    Here you go:

    [(OG-FG)/(OG-1)] x 100

    Taken from White Labs

    For example:

    OG = 1.044
    FG = 1.010

    (1.044-1.01/1.044-1)*100= 77.27%
