I always just battled warm summer water with the cool over night trick. Narry a hitch, kinda nice to not have to screw with aerating and pitching until the next day.

This is what I do.  I transfer to fermenter through a counter-flow chiller with ground water, which usually drops me to about 80 degrees in the summer.  That fermenter goes into the fermentation fridge and I don't aerate or pitch yeast until the temp drops to the desired level.  Most of the time, I can pitch the same evening, but lagers take until the next morning.

My only concern with using the 10 gallon cooler for partial mash small beers is that you may end up with the grain bed too shallow to reasonably act as a filter.

Honest question:  Why bother partial mashing?  If you are going through the effort to partial mash and you are willing to build a 10 gallon mash tun, you can just as effectively go all-grain.  you'll save a few bucks and have even more control over your process.  Just something to consider.

It's going to make very little to no difference plate-chiller vs IC in an ice-water recirc.

I think it does make a difference in that chilling with tap water first won't work with a plate chiller the same way it would with an IC since you are not attempting to bring the entire kettle down to any temp prior to transferring to your fermenter.  I agree with the assertion that I don't imagine there would be any improvement using glycol vs ice water, though.

Also, it is a poor practice to try and emulate professional-scale breweries at the homebrew level.

But by all means waste your time, effort and money. I won't stand in your way.

Agreed.  I think I misunderstood your original quote about only seeing glycol used for fermenters.  I'm guessing now you were only referring to homebrew equipment... whereas I originally thought you meant anywhere.  Sorry about that.

Well an ice-bath prechiller is very inefficient and a waste of ice. The ice would be better served being used once ambient tap-water temp has been reached in the wort. Then once that has been achieved, using the ice-water in a closed loop is extremely effective and efficient. So if the jjflash changes his method slightly he will achieve what he desires without buying more equipment- potentially expensive equipment with unknown efficacy.

That may be true for an immersion chiller... but the OP stated that he is using a Therminator.  For a plate chiller, the wort will be chilling on the way to the fermenter which will require the ice water/glycol be used for the entire chill/transfer process.  Efficiency improvements with this type of setup would be to slow the flow of ice water/glycol or increase the flow of wort based on chilling rate for maximum efficiency.

My concern is that a glycol chiller would not be able to regenerate the cooling fluid fast enough if used. It might work better substituted for the ice-water recirc described above but I doubt it. I've only heard of glycol chillers being used to keep fermenters cool.

Glycol plate chillers are very common in breweries.

Both are good advice.

+1.  Great advice in general... not just for your current issue.

Why not just batch sparge?

+1!  Would save a lot of time and energy compared to what you are doing now.

+2!  One of the best process changes I've made.

Gonna try the B3 Tart of Darkness kit this weekend.

Sparging with boiling water is not a good plan.  You are likely extracting harsh tannins, which may or may not be the "starchy" flavor you are referring to. 

It's the pH, not the temp, that's the culprit in tannin extraction.  If not, no one could do decoction mashes.

That's an interesting point, Denny.  As I understand it, both PH and Temp are factors... but that does lead to questions about how it isn't an issue in decoction mashing.

From How to Brew:

Quote to note from chapter:
"Sparging is the rinsing of the grain bed to extract as much of the sugars from the grain as possible without extracting mouth-puckering tannins from the grain husks. Typically, 1.5 times as much water is used for sparging as for mashing (e.g., 8 lbs. malt at 2 qt./lb. = 4 gallon mash, so 6 gallons of sparge water). The temperature of the sparge water is important. The water should be no more than 170°F, as husk tannins become more soluble above this temperature, depending on wort pH. This could lead to astringency in the beer."

I'm sure thetooth meant:  I highly recommend "NOT" sparging with boiling water.  :)

Oops... that is what I meant.  Do NOT sparge with boiling water.  LOL

Sorry for any confusion there.

Have you ever tried doing a simple infusion mash.  Basically a rest around 152 degrees for about an hour, then sparge with around 170-ish water?  That's pretty much all I do (I'll go lower to 148-ish for more attenuation and up to 156 for beers where I want more body).

I have a march pump and it works fine.  I don't know that there is much of a difference between the march pump and the chugger pump.

All of them will handle boiling temps, even with the plastic head.  I've had one with the plastic head for years and it's been great.  I'm sure the stainless head is cool and looks nice, but it's definitely not necessary.

Add me to the list of people that highly recommend that book.

Best of luck to ya, Sean!  I imagine it feels like buying your first house.

Especially since I'll be living upstairs.  :o

You definitely won't be complaining about your commute!

It tastes good now, so i can't go wrong with just drinking it I guess!  I'll stow a couple away for the sake of science.

Funny... I was about to suggest that exact thing.
