![]() The program works based upon volume into the fermenter (batch size) as the set volume for output and the brew house efficiency (BHE) for the sugar output. Otherwise, the program does not know sugar from grain and calculates a mash efficiency which will include the losses due to mash tun loss and trub to chiller and kettle losses. To do this properly and have the program treat the sugar as the extract that it is, then you also need to change the recipe type to 'extract'. If you take your sugar replacement of the grains, for example. I have been through the math many, many times with BeerSmith and I think you are missing something. You'll only be off by a percentage (the percentage difference is post-boil volume vs batch size) Workaround -> Do the math yourself for PPG. If i'm adding 5 min into the boil it should be based off "ending boil volume" which includes trub losses that i'll suffer as i drain into the fermenter Suggested fix -> use ending volume for calculating PPG by sugar unless I specify adding to "secondary" or something later when the volume will match the batch volume. There's not really a way to link BH eff into that. I really just need the points calculated for the lbs of sugar and divide by the total ending volume. Plus, the BH eff adjustment doesn't affect OG with sugar. I can't lower the BH eff number because it'll jack with my mash eff on the grains in the recipe. ![]() we get less points as we dilute it away with extra 'trub loss'. but divide the PPG we got from the sugar over the volume. So if we add trub loss we need to drop the PPG gained from the sugar. This all seems to check out, because Bh eff is tied to the volumes and mash eff.įor sugar, we have no variable mash eff. DRop BH eff to 50% and my mash eff goes to 100% and my OG is back at 1.018 which is what i'd get if i diluted the wort with double the water. ![]() But to keep a 100% bh eff i'd need to get twice as much sugar out of those grains than possible. I noticed my mash eff jumped is 200% which is impossible, and makes sense here because i need to extract 10g of wort to have a 5 gal batch and 5 gal of trub loss. substitute your 5lbs sugar for 5lbs 2row at 1.036 PPG. because most people just adjust BH eff number until their preboil OG matches what they got brewday and assume that's their mash eff. I'd be further curious if PPG for grains is being calculated off batch volume and not ending boil volume. Then the PPG is calculated with the batch volume and not the total ending boil volume. I bet the addition of sugar is using a mash eff of 100% because it's extract and the efficiency is not variable. Those volumes are user editable fields and not linked directly, they all adjust mash eff up/down to make "bh eff" equal the losses you've inputted. the mash eff is calculated using the BH eff, trub loss, etc. The bug here is that trub loss is not tied to BH eff in any meaningful way. i lowered my BHE to 10% just to see how much it'll lower the OG once we've taken into account the new lower brewhouse efficienty.
