Turning a recipe into a product
Updated

The distance is longer here than in most of this estate, because two of the tests take months and one of them has a legal answer.
A recipe is not a specification
A recipe says "brew tea, add sugar, ferment for a week".
A specification says which tea at what rate, extracted at what temperature for how long, at what starting Brix and pH, fermented at what temperature to what finishing Brix and pH, with what culture at what inoculation rate.
The difference is that the second can be handed to somebody else and produce the same drink.
What a product has
A specification with Brix, pH, titratable acidity and, if relevant, carbonation and alcohol, each with a tolerance.
A process with temperatures, times and a validated treatment step where one is needed.
Shelf life data from retained samples held both cold and warm.
An alcohol result at end of shelf life from warm retains, if it ferments.
A pressure result from the same samples, if it is live or carbonated.
A nutrition analysis, and a compliant label.
The tests a recipe never gets
A warm hold for the full shelf life, which is the test that answers both thresholds and the pressure question at once.
Three reproductions, to confirm the process is a process.
A fill weight and fill level check.
And a taste at the end of shelf life rather than on the day it was made.
What you end up with
A document: specification, process, stability data, alcohol and pressure results, label copy, supplier and grade per line.
That document is what a co-packer quotes from, what a wholesale buyer's compliance team asks for, and what tells you which regulatory regime your product is actually in.
