Building on what flyguy said, you want to save the effort of doing the extra vorlauf and drain, you can get away with a single batch sparge but the way you maximize efficiecy in that case is an infusion to the mash just before first runnings to do two things:

1. Get the grainbed up to 168f, sugar is more fluid at higher temps.
2. Get the two runnings volumes to be close to equal.

Using software is the easiest way to figure what temp and volume to use to get both of those goals met.

Now, I've played around with that method and a double sparge (without the mashout infusion) and it's slightly more efficient than what I just described. How much is hard to say since I didn't do two side by side batches but it averages about 3-4%. If it's a large grainbill, 4% might be worth the extra vorlauf labor.

How long do you let the sparge water sit on the grains if your doing 2 sparges?
In the past I have done a 60 minute mash then a single 15 minute sparge. My efficiency has always been low.

me too.
i let sparge sit for 10 mins, and start vorlauf. takes about 10 mins to drain into the brewpot.

anyone with good efficiency care to take a shot, mine sucks!

I know others may have had different experience, but I saw no significant efficiency increase when using two batch sparges. The caveat here is that you must do a hot mash-out if you only do one sparge, if you want to keep your efficiency up.
What he said. Works for me also. Consistent 75%+ efficiency.

If you read my primer and heed the advice your efficiency will improve. Just to qualify, I get 88-92% and everyone in my brew club that watched the method has also had the same success.

You don't need to let sparge water sit, just stir it in well and make sure it's hot enough. Somewhere between 180-185f should work.

I did my 5th AG yesterday and used the double batch sparge method as Bobby_M endorses (his primer is great!). I was previously using a single batch sparge and was getting OK efficiency but yesterday I got 85% efficiency into the boiler. Nothing else was different than the others which were coming out to 70-78% into boiler. I split my batch into two equal amounts (2.6g per sparge) at 170 degrees, let sit for 10 min, stirred and drained. I really like how that worked out. My brewhouse efficiency on the other hand still sucks at 65%.......

BTW- When people refer to efficiency numbers, are they talking about efficiency into boiler or the brewhouse efficiency?? It seems into the boiler gives you the most accurate number for how much sugar you extracted.

my last @ 62.7% was brewhouse. i never checked mash efficiency. always assumed people posting their 80-85% numbers were talking about into the fermentor numbers, no?

You sparge that hot? I thought that I read somewhere that 170f was a high as you should go.

The sparge water is about 180 - 185 deg. F. Raises the grain bed temp to 160-170. If you are over 170 in the grain bed, no worries, as you are draining almost immediately.

Right, the grain bed never crosses that arbitrary 170F threshold.
