Partigyle for More Beer July 02 2014

Party PARTI-GYLE style on your next big brew day!

"Parti-" = to divide; "gyle" = product of a brew 

A parti-gyle brew is when you run off/lauter the first volume of your mash for a strong beer, like a barleywine or imperial stout, and then collect a second volume of runnings from the same grain for a low-gravity beer. You want to calculate a much lower efficiency for the low-gravity wort, somewhere between 35-15%, depending on your system. 

So this grain may look spent, but sugars still abound! Run some more water through it, and BOOM! you've doubled your brew day output!
