Hello, I was wondering if you folks could add the expected first running's in the recipe builder.
Wondering if any update on this. Is there a simple way to go from conversion efficiency to brewhouse efficiency? For example, if I change mash water volume for 20 to 10 liters, let say I see that conversion efficiency goes from 85% to 55%. How can I extrapolate from this to brewhouse efficiency? Do I simply subtract 30% from the default brew house efficiency of 70%?Ah gotcha, you're looking for the first runnings SG.
Yes, this is on the long term goals, but we need to finalize the overhaul to the mash guidelines sections, and will need to introduce a conversion efficiency in order to be able to predict with any sense of certain a first runnings gravity.
The math is known, and I worked through all of it with Braukaisers data and rederived it from first principles multiple times over the course of the past 10 years, but it does require a big change in mentality on how brewhouse efficiency works that is not always ease to adjust to.
It's not nearly as simple as that table from Kai appears to be, as the input variables are grain absorption, grain mass, PPG of the grain, infusion volume, mashtun losses, mash thickness, and conversion efficiency.
