Step 11: Bottle, Can or Keg

Bottles & Cans: ABV and apparent extract should be checked and compared to Brite Tank values to monitor for dilutions (a common issue at startup) and ensure TTB compliance. Fill volume is also critical to track over time for the TTB, at least three months of regular records are necessary to remain in compliance.
From a process control standpoint, dissolved oxygen and carbonation are important to control for shelf stability, and package integrity tests such as crimp diameter and glue/cardboard fiber tear are some other critical basics to cover.
Having clear and accurate date codes on your product is not only important for wholesaler stock rotation and customer impressions of freshness, they are also critical to batch traceability through your facility should you get a customer complaint from the field.
Micro stability and sensory should be performed on all packages too. Consider increasing your sample size or creating a composite sample to find sporadic issues that will affect some but not all packages.
Although all the same analytics can be done on bottles as on brite tanks, determine what the added value is to your lab before committing to tracking these long-term.
Kegs: Fill volumes can be determined by weight and are important to track for TTB purposes. Dissolved oxygen and carbonation are important to monitor, as is microbiological stability. A Rotech keg or equivalent can help keep tabs on key cleaning, sanitizing, purging, and filling processes.
