Cold Water Sparge

[frunobulax]

I made a Scotch yesterday with all peated malt on my Homebrew rig. I remembered reading something about it on the homebrew forums so I figured I'd try it.
All I did was fill my HLT with cold tap water, dechlorinated it, and fly sparged. It did not affect the run off or my efficiency at all, I usually get 80% with a big
grain bill and that's exactly what I got. The benefit of doing it is, not having to heat the sparge water and it lowered the wort to 110F, so it was easy to
chill with an immersion chiller. It took about 2 minutes to cool with a chiller I made with 1/2 in. stainless steel gas tubing left over from a condenser I wound
for my 3 in. Boka.
I've also done high gravity brew in a bags for Bourbon and cold water batch sparged it down to the gravity I wanted, and that works fine too. (I not gonna run corn through my beer system).
