Hi All,
I am a fairly new brewer but really enjoying the hobby.
I am getting to the point of playing with recipes more so am paying more attention to Beersmith results, and ran across something I don't understand about the calculations of original gravity...
To illustrate my question - if I make an extract recipe that is ONLY 12 lbs of amber liquid extract and use the built-in "Pot (4 Gal/15.1 L) - Extract" profile, it says est original gravity should be 1.078. If instead I use "CCHBS partial boil instructions" (came in the add in "cchbs extract recipes"), it says 1.084 SG.
Both cases are 12 lbs of malt diluted to 5 gallons at the end. Why would the OG be different? I get that IBUs from the hops might be different due to boil volume & gravity of wort issues, but why the difference in OG?
For what its worth, I brewed a wee heavy that the pot 4 gal said 1.085 and the CCHBS said 1.092 and I measured it to be 1.090, so I am inclined to think that whatever the CCHBS equipment is doing to the equation is closer to my reality...
Thanks for any insights,
Parker
