I'm using all my leftovers before my next buying spree. The recipe I
created is thus:
5# Light DME
6# Extra-light LME
1# US 2-row
1oz Northern Brewer Pellets (8%) (60m)
1oz US Saaz (3.7%) (20m)
1oz Czech Saaz (3.8%) (10m)
S-04 Dry English Ale Yeast
I told BeerSmith I'm going to do a partial mash. The software said I
should mash with 1.39 qts of water, and then sparge with 6.43 gallons,
leaving me with a boil volume of 6.41 gallons.
I have 2 questions:
#1 My understanding is that sparging with that much water will draw out
excess tanins? Should I not worry about the tannins because of all the
extracts?
#2 Starting w/ .35 gallons (1.39 quarts) and adding 6.43 gallons ends up
with 6.41 gallon? Can 1 lb of 2 row really hold .37 gallons?

When I do partials I usually sparge with the same quantity that I mash with.
If 4 lbs of grain then about 1.5 gals for mash and 1.5 for sparge. I then
add water to my desired boil volume. If you followed the BS instructions I
would think you are correct in worrying about tannins. My guess is the
program calculator that came up with 6.41 gallons was only trying to reach
the desired boil amount (sparge = full boil minus mash volume) without
consideration for the partial mash. Id ignore it and go with what you know.

1.39qts/pound of grain is not excessive. But, I'd be worried about the
amount of sparge water.
One thing springs to mind though. Why partial mash just one pound of base
grain? If you were adding other stuff like crystals or non-diastatic
adjuncts I could understand but 1 pound of base malt mashed in with all the
DME is just making hard work for little or no gain IMHO. Of course YMMV.
