Speed of batch sparge run off.

[196osh]

Does the speed of the run off when batch sparging make any difference to effienecy?

I can get very very quick run off with the false bottom mash tun of Chris's design. I was wondering if I slowed down my run off could my effiencey increase?

I dont think your efficiency will be affected by run off speed with batch sparging, when you add sparge water before each run off the whole of each sparge should be at the same gravity.With fly sparging the gravity of wort is dropping all the time.

I think slower would be better as you're trying to flush the sugars from the grain and the wort may take the path of least resitance rather than seep through the entire grain bed.

Doesn't matter with batch sparging - just get it out as quick as you can.

Give it a good stir round first, so all the wort is at the same gravity, then just let 'er rip! That's the beauty of the batch sparge - it doesn't matter a bit if the water "channels" through the grain bed or not.

This is what i'd heard too, most descriptions i've heard say run off as fast as it will go. If you're fly sparging... then the speed of run off is quite important.

As ever this forum is an education. Doing AG#3 today so will let rip then, prob save me 45 mins!

Good luck with it!

Excellent, I will just let it rip next brew should save a load of time.

I've also been using the slow and steady method since all graining in January...so much time wasted. For some reason my run off wants to fly out at 100mph so i've been regulating it at a slow pour. That said I've moved my setup from Manchester to London so i'm anticipating all kinds of problems not least with water treatment when it comes to the first brew this Saturday.
