I love this method. I just finished building a No Sparge Electric RIMS system. I am using a sanke keg with a false bottom and a 1/2" coupler welded on the bottom. I really like the bottom draining mashtun. I got 83% efficiency yesterday. No sparge seems to cut out quite a bit of time. I went form 7 to 4 hours with cleanup.
Beside the fact that its just easier over all (I don't like sparging, and I don't like messing with pre-heating mash tun) its nice having an easier process finished in much less time.
Sorry to dig up am old thread, but I am looking at no sparge and have one question (and this seems to be the consummate no-sparge thread).
How fast are folks running off your "no-sparge" sparge? Do you run off fast (batch style) or slow (fly style). I would think that a slowish run off would benefit efficiency. I'll be utilizing a two-keggle system (MLT and HLT/BK) with 15" false bottom. Just curious as I did not see any references to run off rate.

I'm not sure I understand your question. No-sparge relies on a constant recirculation of the wort throughout the mash. There really is no sparge! Once the mash is done, the process is done. I can tell you that my recirculation is totally dependent on the mash-tun draining back into the BK. In other words, I can only pump at the rate that the MLT drains. You have to have a pump unless you are doing BIAB. If I've misunderstood your question, my apologies.

I don't understand it either unless he's talking about draining the MLT into the BK. When I used a cooler with this method I let it drain as fast as it could go. It shouldn't matter how fast you drain it.
I actually do BIAB 95% of the time. I'm still doing BIAB with no sparge and reciculating the whole time in a single vessel. So I never actually have to drain the MLT. I just pulled the grain out of the BK and start to ramp up for the boil.
Ok...Maybe I should have use the Lautering term. I understand no-sparge, I guess I just used the wrong term. After sparging, you have to run-off to the BK. How fast does everyone lauter from the MLT to the BK?

After recirculating ( I guess that can be thought of as a continuous sparge), I drain the MLT into the BK with the valve wide-open as I'm heating to boil. I don't think that after a 60-minute mash w/recirculation you are going to extract any more sugars with a slow run-off than you would with a fast run-off

No sparge would not benefit from a slow lautering unless fast lautering results in a stuck runoff. Run it off as fast as you can without getting things gummed up.
Nice system! So, can this be done safely with a single vessel- a stainless MLT with a false bottom? I have a 15 gallon stainless MLT, and this thread made me think- why not heat the water on the stove top, add grain, then keep the burner running on low? I could hook up the March pump to the MLT outlet and just continually recirc to the top of the tun (although I don't have a sparge arm, it would just be a tube running in there)? Wouldn't this prevent scorching and at the same time give better conversion?
My questions are:
1) is using a march pump on a no sparge large volume mash going to cause it to compact on the false bottom, thus making this not work?
2) is recirculating enough to get decent conversion efficiency (especially with no sparge arm to distribute the heated water evenly) as compared with just stirring?
Sounds like a great way to brew!
