Mash Sparge Combo
« on: April 12, 2014, 12:20:10 PM »
Assuming you have room in your MT, what would be the problem with doing a normal mash then add the sparge water, stir, vorlauf and drain?

Only thing crossing my mind is pH but it seems like all the first runnings would buffer it down rather than up.

I suppose there might be slightly lower efficiency because your not rinsing as well.

Anyone try this before?

Sounds like single/no sparge batch sparging to me.

That's no sparge.  If you add the water after conversion, pH shouldn't be much of an issue.  Your efficiency probably will go down some.

Awesome, I believe im assimilating all this stuff. Im not going to do it cuz I dont see much point but I was curious if I understood what the effects would be.

I had to do that in a very small brewery due to equipment limitations. I'd sprinkle the "sparge" water on top as gently as possible to avoid mixing, then drain the tun. It did buy us roughly a 5-10% efficiency bump depending on gravity. At home? Just no-sparge.

Yeah, this is no-sparge.  Your efficiency will suffer, only get upper 50s / low 60s.  However it's a viable method if you want to experiment.

5-10% bump up? From what? Actual no sparge?

I'm never going to do this but I find the brain floss interesting. If I'm understanding the process right, the mash thickness is for enzyme density. Sparging is to rinse sugars left behind. So, true no sparge costs you points in both enzyme density and rinse. Mashing at about 1.5-2 then adding all of the water seems like middle ground.

I no-sparge and I really only start to see my efficiency drop significantly once I get to 4 qt/lb. It is kind of weird that I get the best efficiency on big beers like Quads and Barleywines, and lower efficiency on my session beers, though.

Since I have a 2 vessel setup, I have played around with no sparge configurations, and see my best efficiency from mashing all the water at once. My old mash went like this:

mash with 1.75qts/lb, mash out, added water to my preboil volume(7.8 gal). Recirc 10 min, pump to kettle. Average 62% eff, malt conditioned crushed with a .22 gap.

New mash goes like this:

mash with full water volume(we'll say 9 gallons with grain loss), mash out, pump to bk
Average 70% eff, exact same procedure/crush
