Hey guys,
I'm getting ready to do my first all-grain batch in the next couple of weeks, and I've been reading like crazy. However, there are still a couple of things about sparging that aren't clear to me.
I'll be batch sparging in a converted cooler mash tun.
All the books I've read describe sparging once, but based on the volumes of water and the "rule of thumb" ratio of 1.25 qt./lb of grain, as well as some of the descriptions I've seen in transcribed BeerSmith directions, it seems I should be sparging twice. So my first question is, how many times do I sparge if doing an all-grain batch sparge? Once or twice?
The second question is the temperature. Do I sparge at 170 F to "mash out," or am I still trying to achieve some more conversion with the sparge (and thus, should be sparging at 155-ish)? The literature I've read said to infuse the sparge water, stir the grains, then leave it for 10 minutes before vorlaufing and draining. But what temperature should my sparge water be?
Thanks for any insight you can provide.
