with a SG of 1.045.
I let it get going good then pitched it into the big beer.
Now how would you figure the alch% on this?
Assuming the FG will still be around 1.010 after 3-weeks?
I would figure the alc of the krausen alone and use the ((alc1 x vol1) + (alc2 x vol2))/ (vol1+vol2)
That should get you close
