[COHO] All Grain Barrel Filling Brew

[Mike T]

Jim, you don't have to know what your efficiency is to contribute. From 
Brett's recipe, your target gravity after the boil is 1.090. So take the 
last two digits (90) and multiply it times what your volume of wort will 
be in the kettle after the boil. If it's 5.5 gallons then 5.5*90=495. 
Now work this backwards to find out what the gravity of the wort will 
need to be pre-boil. Your volume will need to be about 6.5 gallons at 
the beginning of the boil. Take that 495 number and divide it by 6.5 and 
you get 76 or a gravity of 1.076.
Lets say that you didn't get a gravity of 1.076 at the beginning and 
it's less than that. You would have two options. Either boil it a little 
longer (before adding your first addition of hops) or add some malt 
extract. Both have some disadvantages, but still work. Boiling it longer 
will end up giving you less volume in the end and adding extract... well 
you know how I feel about using extract :)
This may sound more complicated than it really is. Since so many of you 
are brewing at the same time, you have plenty of help. Kris's 
refractometer will come in handy too. As always, fell free to call me 
anytime. My new number is (843) 793-9676. And take lots of pictures. I 
already miss your happy smiling faces.
Brew on COHO!
