I'm wondering if there's anyone else out there that has noticed significant errors in how ProMash calculates the SG. I just recently started creating my own recipes, so my knowledge of how much pppg each malt contributes was severely limited.
I brewed 5 gallons of brown ale last night and in my promash recipe I had only 5lbs of DME at 46 pppg and some steeping grains. However, promash predicted a SG of almost 1.057. After brewing I took a hydro sample and it was at 1.042 (had a bit more than 5 gallons, so near enough the 44-46 pppg standard.
I'm wondering why Promash was so far off in their SG prediction. I guess at least now I will have a session brown ale....:/
FYI, I put the same recipe in BeerSmith and got the correct OG prediction. Weird...
