I probably do not understand something here and I am hoping someone can help me.

I do not want to make this over complicated so I will use the most basic recipe with even numbers.

10 lbs of US 2 Row (possible 37 points per lb/per gallon)

5 Gallon Batch

No Sparge Full Volume Brew

60 Minute Boil

So in my world here are the numbers I come up with.

7.5 gallons of water into the Mash tun

100% extract = 370 points/7.5 = 1.049

If I put that into Beersmith there is what I get.

I understand what is going on here, the batch size is 5 gallons and they are taking that number and doing 370 points/5 gallons = 1.074.

My question is the est-preboil gravity of 1.064, they have it listed as est-preboil volume 6.5. There physically is not enough sugar in the grain to hit that number as the most you can come up with is 1.056 with the prevail volume of 6.5 if you hit 100% conversion and lauter effeciency.

So the end question I have is if my information above is correct...

1) Am I missing something?

2) How do I correct this in beer smith to start giving more real numbers?

Thanks in advance,

Jeff
