Batch sparge sparging question
« on: January 16, 2016, 06:36:30 AM »
After you add the sparge water, do you let it sit for a little bit, or do you start draining after another vorlauf? Also, does runoff speed matter, or is that more for fly sparging?
Thanks for any help.

After you add the sparge water, stir the mash, vorlauf and drain.
Run off speed doesn't matter, at least on my system.

I suggest stirring it all after adding the sparge water, then vorlauf til clear (sometimes it helps to run the vorlauf slowly to get the grain bed set again), but once it is clear, I let it rip, usually.  If using a lot of adjuncts, consider adding rice hulls to make it easier to drain.

I let it sit for about 5  minutes or so, on the theory (untested) that reaching equilibrium between the  sugars in the grain and in the water takes some time.

I let it sit for a few minutes with the idea that the vorlauf will clean up more quickly if the grain has time to settle for a bit.

I have no evidence to support this but it has always worked for me.   :)

I used to let it rest for 5-10 minutes. Now I just stir and run it off. I've seen absolutely no difference except for time.

Same here. I've never noticed a difference either.

I did the testing for you...many, many times.  It doesn't matter.  You gain nothing from letting it sit.

Same here, I used to give it time to settle. Don't need to, start vorlauf right away.

I wasn't expecting to learn anything from this thread. I always wait a few minutes and now. Won't. I do let it drain fully open.

What will you say next? That "equal runnings" has no effect on efficiency?

You devil!  ;)  If you keep the runnings within a gal. or so of each other, the difference in efficiency is so small that it just doesn't matter.
