A variable ingredient addition that can be both tracked (for inventory) and has a “reporting tag” so it can be viewed in the analysis tab for comparing against previous batches. Useful for mash acid additions that would be added based upon mash pH readings and may entail multiple additions throughout the mash.
Thanks for the suggestion, Tait. If I’ve understood you correctly, this is a duplicate of Recipe-level variables for Calculated Fields, e.g. allow "Add ingredient" quantity to be the result of a calculation
If so, can you please vote for that one and confirm for me so I can close this thread? If not, can you please explain further? Thank you.
Hey Luke,
I read through that feature request thread but I am not sure that request as written accomplishes what I’m hoping for here, though maybe it could. I’ll explain it out a bit more and if you see how it does this already then let me know. We can then close this thread and I’ll vote for the other.
The “variable ingredient” as I’m referring to it, would be at recipe level a “target or estimated” amount by volume, weight or units. But at the batch level the operator would enter the actual added amount/volume/weight (this recorded amount could be deducted from inventory and could have a reporting tag). The amount added though is not necessarily the result of a calculation (which is what I understand to be the purpose of the Calculated Fields) maybe this is where my request differs?
If I am reading the example of the water back calculation accurately that is a fairly straight forward calculation of dilution. On the other hand, calculating a mash acid addition to move an in-process mash to the desired target pH value is well outside of my knowledge and I suspect most of the brewers without chemistry PHDs just estimate based on experience with that particular malt bill and that particular water chemistry: add acid, measure pH again. So I don’t think we’d want to rely upon a calculation using a measured pH to determine mash acid additions. I suppose if someone was skilled enough to basically re-write BruNWater type calculations in Breww then that’d be killer but definitely not something I’d be able to do.
