man im glad i found this thread! i have been thinking about trying something like this, and now i can see that it works well before i even try it. all i really need is a pump. i have a 10 gallon kettle and a 10 gallon cooler mash tun. i have another kettle that i currently use as a HLT for batch sparging, but recirc/no sparge makes sense for medium gravity brews.
question: It looks like most of you have been doing 60 minute mashes. have any of you checked to see if your conversion is getting done quicker? i know some brewers are doing shorter mashes, and checking for complete conversion with iodine. this would help shave even more time off of the brew day. have any of you tried this? also, since you are recirculating with all of your brewing liquor and supposedly its all the same gravity, you could check with a refractomer.
