Hi,
Today I did a split double batch - I mash a 50l batch, take 'half' off and hold it at mashout, boil and chill the first, then onto the second. I say 'half' because my 30l urn can't really hold all of the preboil liquid.
I've ended up with 46l between the two batches...Probably pretty close to predictions given the double trub loss, but I'd like to calculate the OG against the recipe just to be sure. Problem is, there are two OGs. I have 28l of 1.052 and 18l of 1.055.
Is there a calculation to help me find the OG of the 46l total? I am sure it can't be too hard to figure out, but its not really my strong point. I imagine lambic blenders must do something like this at the other end of the process...
