My questions arose due to me doing a brew today where I decided to use NO hops, and just wondered what the BIABacus would to in that instance. Not critical to me really, just curious!
Currently, that PLG number is just based on simple dilution. This is appropriate when it is only dilutions being made. It is not appropriate though when a sparge is involved and I'm pretty sure that Richard does do a bit of a sparge. The easiest way to picture why this is a problem is to exaggerate things...mally wrote:I won't even pretend to know how the BIABacus calculates...
PP, I didn't know that the PLG formula was flawed in your opinion. I know it was a pita trying to wrap my arms around why I wasn't hitting that estimated gravity, and I don't sparge. I add water before the boil. I would scrap that dude.PistolPatch wrote: Also on the weekend I looked at the PLG formula. If we all want to save ourselves a heart attack, let's just think of PLG as meaning Post-Lauter Gravity with Post-Lauter meaning, if you are a sparger, the gravity after your sparge but before your pre-boil dilution if you have one.
I'd forgotten, but the weekend reminded me, why all the commercial software avoids a Pre-Lauter Gravity figure or, if any amateur software comes up with it, it is flawed.
