I'm a fairly long time user of BS 2 and now using BS 3. I just did a simple 5 gallon single infusion ale batch and blindly followed the sparge amount calculated (not paying close attention) and realized too late that I'd collected way more pre-boil volume and consequently came in with a lower than desired pre-boil gravity.
I did a post mortem on the BS 3 calculations using the "Sparge Volume" formula that I found in a previous forum entry.
Per Brad's post, the formula should be: Sparge Volume = Boil Volume + Grain Absorption - Kettle Top Up + Mash Tun Deadspace - Mash Volume.
The numbers I pulled from the recipe page were:
Est Boil Volume = 6.89G
Grain Absorption= .85 G
Kettle Top Up= 0
Mash Tun Deadspace= 0
Mash Volume= 2.76G
These numbers calculate out to 4.8 gallons for sparge (if my math is correct (which is admittedly not great in the best of times))
BS 3 came up with 5.53 gallons
Is there something else in the program that might explain the difference of .55 gallons?
I'd appreciate any insight on this. Thanks
