Ah, not if you do it right. I hit 80~90% efficiency and I use a braided hose in my Mash Tun. You only get channeling if you Vorlauf\sparge too fast and disturb the grain bed. It isn't the equipment, its the technique.

+2. Great beer can be made with either method of sparging. Also batch will make your brew day faster. I consistently hit 75-80% with batch sparge and have since batch 1 (which was an oh crap I wasn't ready to mash but I just activated the smack pack for the PM batch instead of the extract and grains batch I guess I'm mashing batch). I have an extra 5 gallon round cooler for hlt and extra pot for heating sparge water so I have been toying with trying continuous sparging but if it ain't broke don't fix it right?

The reason to try batch sparging in a situation like this is that it eliminates your lauter system and technique as possible causes of poor efficiency. If you batch sparge and your efficiency goes up, you know that your lauter system and/or technique is the cause. Once you know that, you can either correct it and go back to fly sparging (not me!) or just keep batch sparging. Most people who try batch sparging stick with it.

+1 again. I started fly sparging, but once I gave batch sparging a try I havnt gone back to fly sparging.

That's not what Palmer says. http://www.howtobrew.com/appendices/appendixD-1.html

I believe Palmer in this instance when talking about fly sparging.

I use a bazooka screen in my mash tun. I consistently get 72-73% brew house (kettle) efficiency. If I stir the heck out of the mash I can get 75%. PS. I batch sparge.

**chuckstout** · 07-09-2012, 02:23 AM

I use a bazooka style screen 5G cooler and have had roughly 80% eff over the last 10 batches

I believe empirical data. You stated an absolute, that with the equipment in question (mashtun with a bazooka style screen sans manifold,or false bottom), one cannot achieve efficient rates fly sparging. I do it all the time...so your statement is incorrect.

I have no problem with those that have recommended to the OP that he give batch sparging a try as a means to address his low mash efficiency, sounds like good advise. Telling someone that something cannot be done, when it can however, isn't.
