What I did, originally is make an extract ingredient for the free wort, thinking I could steep or mash the ingredients we added and use this a late addition in the project recipes (which is exactly what was done operationally). Say you wish to sour a beer with a stale one or blend beers. You can do this but BEWARE. Beersmith will let you nbut it doesn't really understand. (As a side note, if you ever want to do this, you will adjust the yield parameter to force the 'potential' to equate to your worts gravity ... even if you plug in a yield above 100% and get a red error-looking response thats okay).
Gotta run. More details later.
Yeah I didn't understand a word he said either.
So I've been working on another project, which I'll post about soon in Bottling and Kegging but here is the latest update on the free wort.
What BB2 did once he made an extract ingredient out of the free wort recipe was add it to our project beers as though it was an LME i.e. in pounds.
But he also used it in gallons to create the volumes for top up water and batch size and broke BeerSmith in the process.
So I went to do an update to this thread for the rest of the wort which was basically straight up and saw this:
Well obviously something was wrong so that is when BB2 found out that BeerSmith was seeing the gallons of wort as water so it was diluting the recipes.
Got some help from the BS forum and used excel to fix the math so we got revised numbers on all the batches.
We had enough wort left after the three previously posted to do another case and for this one we just steeped some carapils and quick oats to add some body, no hop additions, pitched Nottingham in 2.67 gal pasteurized free wort @76f.
BeerSmith had:
Est. OG 1.059
IBU 29.8 BU:GU .50
SRM 16.2
ABV 5.8
Once revised it was:
Measured OG 1.058
IBU 26.6 BU:GU .449
SRM 27.2
ABV 5.6
Measured FG was 1.015
Bottled 24 12oz 3/20/14
BS color revised
I'll put the other revisions in the original posts as an edit.
