Using a Czech Pilsner (all grain) recipe from Northern Brewer (shown below) and inputting the step mashing schedule and additional steps/Infusion into the Infusion calculator on this site, the total water volume yield is just over 7.5 gallons (see below) which exceeds my Boil volume target of 6.75 gallons to yield 5.5 gallons. How do I make the adjustments, or do I just take the volume I need for boiling, and leave the rest in the mash tun? Or do I adjust the water to grain ratio? Or? And how do I sparge with no volume left? And this is a relatively light (weight-wise) grain bill for 5-5.5 gallon batch, the question gets bigger with larger grain bills (12-13 lbs). Ps. I would show a pic of the calculator results but I can't upload the screen shot image from my phone without a URL.
