I am doing partial mash in a bag in a cooler, and I am reaching my volume and gravity targets while the sparge water is still indicating that there is a lot of sugar left in the grain. Here are the numbers from yesterday's brew: Mash 5 lbs grain with 7.5 qts of water (1.45 qts/lb) at 150 F for 45 minutes. Recirculate 2 quarts, then drain into the kettle. Add 6.5 qts of sparge water to cooler for a sparge temp of 165, let it sit for 5 minutes. Recirculate 2 quarts, then drain into the kettle. At that point I had about 3 gallons (my target) and a gravity of 1.049, but the last sparge water still had a gravity of 1.035. That tells me that even though my efficiency is high I am leaving a lot of sugar behind in the grain. What can I do to get that sugar to come out sooner? Less mash water and more sparge water? Let the sparge sit for longer? Sparge twice with half the volume in each?
This is a good kind of problem to have, and I could just ignore it, but the waste bugs me.
