One: choose treated or untreated
The two routes. Everything downstream follows, including how far the product can travel and what the label says.
Two: if treated, establish the process
Control measures producing at minimum a 5 log reduction, documented, and effective for at least as long as the shelf life under normal and moderate abuse conditions. That last phrase is doing real work.
Three: if untreated, lay out the warning
Word for word, in a place it will be read. It is not optional and it is not paraphrasable, and designing a label around it afterwards is harder than designing around it from the start.
Four: set the shelf life honestly
The 5-log reduction has to hold for the whole of it. A longer stated shelf life is a longer period your process has to be shown to cover, which is an argument against optimism.
Five: decide the fill
Hot fill, cold fill with a preservative system, or cold fill with a short refrigerated life. The three give very different container requirements and very different businesses.
Six: choose the container against the fill
A hot fill needs a container rated for it. PET is the catalog's largest material and it has the lowest service temperature, which is the single most common mismatch in this craft.
Seven: then the closure and the tamper evidence
A beverage is expected to show it has not been opened. This shelf carries no tamper evident band, which the containers section says plainly.
Why treatment comes first
It constrains the shelf life, the distribution, the label and the container, in that order. Choosing a bottle you like and discovering it cannot take your fill temperature is the expensive sequence.
And write the plan down as you go
The hazard analysis, the control measures and the records are a document that has to exist. Building it alongside the process is far easier than reconstructing it once production has started.
