Packing the jar

Fill weight is a label claim

The net weight on the label is a statement about every jar, not an average across the run. Packing by eye produces variation, and variation means some jars are below the claim. That is a labeling problem rather than a quality one, and it is the kind that is easy to fix early and awkward to fix after a label order.

Weigh into the jar until the hand is trained, then spot-check through the run rather than trusting that it stayed trained.

Appearance is part of the product

A pickle is bought partly on how it looks through glass, which makes packing a presentation step as well as a volumetric one. Spears packed deliberately look like a product; the same spears tipped in look like somebody was in a hurry. The difference costs seconds per jar and it is visible on a shelf next to a competitor.

It also costs consistency if it is done differently by different people, which is an argument for deciding the pack pattern once and writing it down rather than leaving it to whoever is on the line.

Pack tight enough that things stay under

A loose pack lets the contents float once brine is added, and anything above the brine is in a different environment from everything below it. That is the same rule as the ferment, applied at the jar scale, and it is the practical reason a tight pack matters beyond looking better.

Tight is not the same as crushed. Forcing a jar damages the product and drives the fill weight up past the claim, which trades one problem for another.
