Default batch sparging

should one just let the sparge water out quicly as possible or should one use some finess and let it drain out slowly in to the kettle, i have read many ways on how to batch sparge. How do you do it?

I have had no problem just letting it rip. I hold the hose higher than the tun, open the valve all the way , and slowly lower the hose till the wort flows.

EDIT: I have a 79% brewhouse efficincey with my equipment, having said that I mill my own grain.

what is your average efficiency on your equipment, i have a round cooler with a s/s false bottom, very simple

I vorlauf until the wort runs clear and then just let er rip.

I have been between 74-77 percent on each of my last dozen brews this way using a rectangular 50qt (?) cooler with stainless braid.

With a false bottom you might want to gradually increase the flow.
I know if I just throw the valve open full bore it almost always leads
to a stuck run off.

I vorlauf with a slow runoff, then step it up for collection. I don't let mine rip because some characteristic of my home-made tun produces air bubbles in-line at faster runoff speeds. When all's said and done, i never get less than 70% efficiency.

Part of the appeal of batch sparging is the time savings, so I let 'er rip after settling the grain bed.

I actually go really slow and get eff around 82-85%. However, I also do two sparges so that may be were the extra efficiency is coming from.

I dont think the speed of your lautering process makes a difference when batch sparging.

Definitely double or triple batch sparging will increase your efficency due to the fact that you are rinsing more sugars from the grain, but I fail to see the correlation between a slow run-off and increased efficiency.

Some may be concerned about a stuck sparge, but I haven't had any problems with slow or stuck run-offs by opening the valve all the way after allowing the grainbed to settle between spargings.
