When you say adjust accordingly, do you mean to simply add water to the fermenter as I have been doing. Or, the last two brews have found me about 3/4 of a gallon short. Should I just add 3/4 gallon to the sparge volume that Beersmith calculates for me?
I personally stay away from adding unboiled water to my fermenter. You could add 3/4 of a gallon to the mash-in. I don't think I would add it to the Sparg, you may get some off flavors from over sparging.
After thinking about this for a few min, it got me to thinking that there has got to be a better way.
First of all make sure you have your equipment setup correctly. I copied a profile that was close to mine and renamed it to my personal equipment and adjusted the profile to fit my equipment.
Now then. If you look at your equipment settings in BeerSmith, you could compensate or add this amount in a couple places. Assuming that "your" Equipment profile is good
1. You could add 3/4gal to the "Top up Water" and then everything would be fine.
2. You could adjust your evaporation rate higher to compensate which would add extra water to the boil.
3. You could change the "Lost to Boil Trub and Chiller".
4. You could add it to the "Top Up Water for Kettle" (I would choose this one myself)
Hope this helps
