Hey have any of you guys been following the HB digest as of late? Some pretty good back and forth in reference to fly vs. batch sparging. Steve alexander is even claiming batch sparging is more efficent. I'm a batch sparger but I always thought that fly sparging was more efficent in a slow sparging system that avoids channeling. But it sure is easy to not have to worry about channeling and just stick a stainless steel braid on the the outlet of the mash tun and let'er rip.
It's kinda hard to following everything they are saying but red baboons have something to do with it.

Yes, I've been following it as well. Very entertaining. I'm heading there next for the latest installment. Not only is the fly vs batch argument interesting but I'm also interested in Mr. Alexander's comments about deliberately limiting efficiency to no more than 75%,
FWIW, I've done both fly and batch and fly seems to give me a little better efficiency with my system without taking much more time. But, I'm willing to give the batch sparge a couple of more goes just to see for sure.

I love batch sparging, it's just so easy and quick, the only time I fly sparge is if I'm doing a big beer.

I've been fly sparging with a paristaltic pump and it is totally hands off! It gives me time to get the fermenters cleaned, and the BK ready.
Fly sparging also gives me more consistent efficiencies that are less dependent on the OG of the wort. BUT, sometimes the efficiency is TOO HIGH, and the final runnings are less than the recommended 1.008 (though I haven't noticed any undesirable tannin flavors)

Richard, I would guess that you have relatively soft water (although Southern California tap water is often notoriously alkaline) and the relatively low pH is preventing tannin extraction even with the thin runnings at the end of the sparge. However, I have noticed a graininess that can result from oversparging. It's less objectionable in some styles. Taste the final runnings and you'll know what I mean.

I've been following that discussion with some amusement, since I kinda fired the opening salvo by claiming that batch sparging can be as efficient as fly sparging. I'm enjoying reading Dave Burley's scientific explanations of why I can't possibly be experiencing the things I'm experiencing.

Bill, I adjust the pH of my mash with lactic acid. I shoot between 5.2 and 5.3. That may explain why I'm not getting tannin extraction. But I'm brewing again this weekend and I'll taste the last runnings and report back on this thread.

For the few in the Philly area:
Pats or Geno's?
I batch sparge because I found this site and Denny's set up first. I personly feel the debate is like arguing who makes a better cheese steak. For the record, I like Jim's Steaks at 4th and South st.

Really silly isn't it? If you have the mash tun capacity, you have a choice of batch or fly. Pick one, master it and be consistent. Batch to batch consistency and familiarity with your system and process makes brewing repeatable and easy. A simple grist adjustment will make up any difference in efficiency either way. We are talking about less than a buck per batch difference; the pay back for being consistent is worth far more than that.

The guy (Chad?) that's the most adament that it can't be as effecient obviously doesn't even understand the concept. 2 people have pointed out that he's describing no sparge yet he still doesn't get it. And he points out he's been brewing 30+ years!
They're starting to act like a couple of folks around here about it

Denny says: ...scientific explanations of why I can't possibly be experiencing the things I'm experiencing.
There is a pretty famous piece of scientific work showing that it is physically impossible for bumble bees to fly.
As I have heard said "In theory in should be the same as in practice. In reality, its not."
