Just for the record, everything I stated was from personal experience. I wouldn't say I've "mastered" either, but I have "been around that track" with both.
Just curious Blktre, have you mastered both? And I appreciate all of your constructive comments you added to the discussion.
To start off, the main thing is to find a technique your happy with. You like the results, then its a good one.....
Sparky, i can say Yes, i feel ive mastered both techniques or variations of both and pushed my brewing abilities and equipment to be able to say that. Im not saying im god or nothing like that, but ive always pushed different methods to see for myself....
Heres my take on it....
My equipment is a 1/2 barrel HLT/HERMS, 48 and 60qt IceCube MT rigged w/ copper manifolds and i use either a keggle or my 25g SS Kettle. I use a pump on a 2tier w/ the HLT up high. Ive used braids, FB's in coolers and keg MT's.
Batching will take up some extra room for water and getting 2 batches is the way to go if you can do it. Theres no need to stir the bed in between batches. My eff. stirring or not stirring resulted in the same and that was in the high 70's to low 80's. So just varlouf once and i think you will be happy. A 10g batch should take around 30 min. to vorlauf and get your preboil vol. But, ive never gotten crystal clear wort to the kettle doing this.
Also, i had to wait longer to get the preboil vol. up to a boil. So that time needs to be considered. And my gravity never dipped below 1.015, no tannin concerns.
Fly sparging really needs to take into account the tun geometry. So i prefer a manifold per John Palmer. A braid wont cut it, it will channel. Manifold and braid cost about the same to build. I can replace water for batching w/ grain, so i can get more in there. Once the In and Out is set, i can still get 13.5g preboil in the kettle in about 35 min. w/ eff. of 80%. Same as batching. As the wort hits the kettle, i light the fire. When i reach my preboil vol. im already boiling. No waiting like batching.
I like recirculating systems. Once i dough in, im heating sparge water. With about 45-60 minutes into the mash i recir. for 10 min. to get crystal clear wort and hit mashouts at the same time. This cuts down on my time as well because i can convert, set the bed up as a filter to get the crystal clear wort, and hit mashout. I never get stuck even pulling w/ a pump. You will need to check gravity towards the end for tannin extraction, but my system is down so good, its almost a waste of time.
I know folks cant do this, but ive found the technique to work well.
But even at that, varlouf should take about the same amount of time w/o a pump. The big difference in time i think is waiting on a preboil vol. to reach a full boil after sparging or already boiling by the end of the sparge.....
I can think of some more, but thats a quickie......ive found in my experience.....
