The last three beers I have brewed have been no sparge mashes. I have seen no loss in efficiency. Now I find myself wondering why I would ever sparge again. I brewed an IPA today. BeerSmith predicted a 1.058 OG with a batch sparge or no sparge. My no sparge came out at 1.057.
Eliminate a whole step, and the time that goes with it. No juggling a second water salt addition…
So someone tell me why I should ever sparge again.
Because of the mash thicknesses involved, I was actually getting better efficiencies on high-gravity beers than session beers when I started doing no-sparge. I have since lengthened my mash time a bit, and also started reserving some of my mash water to keep my mash thickness around ~3 qt/lb for a maximum. That has brought all my brews to a dependable 82% +/- 2% efficiency from 1.035 all the way to 1.100+ OG.
I agree, sparging is a waste of time and I suspect it might actually be harmful as it creates more turbid wort and therefore possibly worsens chill haze later, but that’s just a hunch. I’m not sure why so many brewers still do it. Maybe people like the old rituals involved in all-grain brewing. I reckon it might eventually fade out, like secondary fermentation largely has done.
I usually don’t, but I might for an upcoming batch. I have a 10 gallon kettle, and I usually max out brewing 6 gallons of 1.05-1.06 wort. I might sparge to be able to get the volume/specific gravity. I’m usually mashing at ~2.5 qt/lb. I’ll probably have dunk sparge in an old 5 gallon kettle. I’m definitely surprised how well no sparging is working, I never expected to enjoy the processes so much.
I just always assumed it would mean a big decrease in efficiency…until I tried it. I’ve got a 15 gallon MT for 5 gallon batches, so I can no-sparge a pretty big beer.
Do you add all the water to the mash tun at once? Or do you dough in with a lesser amount to keep the ratio reasonable and then add the remainder before recirculating and draining to the kettle?
The recipe I’m looking at if added the total water volume it would be 3.8 quarts per lb. I assumed that would be too high? 8 gallons in 8.3 lbs of grain.
I moved to no sparge BIAB lately. I really like the simplicity and like many others, I find the efficiency penalty to be quite manageable. My efficiency dropped from 78% to 72%. Although, I had one BIAB batch recently with 78% efficiency.
I tried no sparge twice for the LoDo approach and had massive efficiency losses ~55%. I recirculate the entire mash and still give a decent stir in the beginning.
I do use the lhbs grind but it’s the same grind I’m using to get 75+% with 1 batch sparge.
What am I missing as I really want to do away with the 3rd vessel
Are you doing single infusion? When I started doing no sparge (for Low O2 as well) I went from 75% down to 55-60%, then I started doing a few infusion steps and things went back up to about 70. I don’t know if the difference is based on the fact that I have the multiple steps in there, or that the total time of the mash from dough in to boil probably increased 20%, or that I am agitating the grain bed more times throughout the process.
My “shoot from the hip” answer would be the longer mash time and the stirring (very gentle, just enough to mix in the boiling water addition) at each of those steps is what does the bulk of the increase.
I’ve been no sparging for a couple of years as well and I love how simple and easy it is. Of course you have to have a big mash tun to handle it. I have a big 30 gallon mash tun so I could do a 10 gallon 9% beer in there to max it out. If I wanted even more ABV I could just use a little bit of DME to get there. On average I’ve been getting 70-72% efficiency. I’m running some huge water to grist ratio’s though. Often 3:1 or even 3.5:1. I’ve noticed that the mash can take a little longer on some of those bigger ratios, maybe 90 minutes. I have very hard water so it’s nice to not have to acidify any sparge water or do any additional calculations. The beers have turned out good and I don’t think I will be returning to sparging any time soon. It also helps to have a large kettle. I have a 30 gallon so I can heat my 16-20 gallons of strike water very easily and then transfer it to my mash tun via pump or gravity. I just transfer it right back into the kettle afterwards. A perfect no hassle two vessel system.
Yes I use bru’n water and my pH is generally around 5.3. I do a single infusion mash. I stir a decent amount at the beginning and then recirculate the full 60.
Regarding" lower-gravity beers being tricky,"how are they problematic for you? I brew exclusively in the 4.5 ABV to 6.5 ABV range, and all my beers taste good to me and others like them as well. I do have to admit that I’ve never entered any competitions with them.
In fact, we are having a great conversation about this very talk in the other thread that I started “Mash Mystery w/ Vienna Malt”. My first low gravity beer using this method did not produce the gravity I was looking for at a 3.3:1 WTG ratio.
