Hi Guys,
Hope some can help me with this. I am brewing a three gallon batch of 10% ABV IPA. These are my instructions for the mash:

Mash In 154F, Add 14.50 qt of water at 171F for a step temp of 154F for 60 min

I'm fine with that, but then the batch sparge says this:

Batch sparge with 2 steps (Drain mash tun, , 2.00gal) of 168.0 F water

Does that mean two sparges of 2gal each? Or does it mean two sparges of 1gal each?

My guess is two at 2gal each. I'm sure 11.6 lbs of grain will soak up a lot of water.

Thanks a lot!

First, I think 154 is too high for a 10% IPA. You will probably want to go with 150 or so.

How many pounds of grain are you using? 11.6? That's about right.
Remember that your grain will absorb about .125 gallons per pound of grain. So figure you'll "lose" 1.45 gallons right there out of the 3.625 you're mashing in with.

That means you'll have a bit over 2 gallons after the mash. What is your boil volume? You'll want to use enough sparge water to get you to your boil volume.

Ah, you know Yooper, I'm an idiot. It says exactly how much water I need. All I had to do was add it together.

Is there any advantage to splitting the sparge into two batches?

And as far as the mash goes I had it at 150F ever since I've been working on this recipe (weeks), and I just changed it to 154F. Not sure why I thought that was a good idea. Thanks for the help!

There may be an advantage to splitting it into two batch sparges normally, but it really depends on how much sparge water you have. If you split this into two sparges, two gallons in each, you may not have enough liquid to really get the grainbed fluid and stir well. In that case, many people will do one round of batch sparging.

Ill just do what ever looks best when I get there. I was just trying to figure out BeerSmith wants me to batch sparge with two steops in stead of one.

I don't have the new Beersmith, but my version has an option that you click on the "batch sparge screen" that says something like "use 50% of the batch sparge volume". That could be why it's tell you to do it twice.

I am doing my first all grain batch today, out of all the instructional videos I've seen I never heard of doing a two step sparge. Beer smith is throwing me for a loop, will it be a real problem if I just do a single sparge? I thought that would do a better job at rinsing the grains.

There are a lot of different factors that affect this but the first reason to break a sparge up into several batches is if your mash tun can't handle the full sparge volume. This happens to people who make the mistake of building a 5 gallon mash tun and then try to make a big OG beer. There is also sometimes a small boost in efficiency when breaking the sparge up and how much of a boost depends on a couple things. It's more effort, but I think it's good liquid handling practice for new all grain brewers anyway.
