The batch is inconsistent

Variation between jars is the failure nobody writes about and the one a wholesale buyer notices first. It is a measurement problem before it is anything else.

Where variation comes from

Brine mixed by volume rather than by weight, so no two batches are the same concentration.
Salt scooped rather than weighed, which is the same problem with a different ingredient.
Packing by eye, so fill weight moves from jar to jar.
In a ferment, different positions in the vessel having different conditions, particularly near the surface.

Why it matters more as you grow

A customer at a market buys a jar. A wholesale buyer buys a specification and expects every delivery to meet it, and the first inconsistent case is the one that ends the relationship. Consistency is the thing that distinguishes a maker who can supply from one who can only sell, and it is almost entirely about measurement rather than skill.

The fix is dull and it works

Weigh things. Weigh the salt, weigh the water, weigh the product into the jar, and write the numbers down. A kitchen scale removes most of this page, and it is the cheapest piece of equipment in the whole operation.

The fill weight in particular is worth fixing early, because it is also what the net weight on the label claims. A jar that varies is a label that is wrong on some of them, and that is a different kind of problem from an inconsistent product.

The ferment caveat

Some variation in a live product is honest and cannot be engineered out: a ferment is a biological process and two crocks will not be identical. The answer there is to describe the product accurately rather than to promise a uniformity you cannot deliver, which is a labeling decision as much as a process one.

Consistency is what a specification is

Turning a recipe into a product means writing down what the product IS, in numbers somebody else could hit: the ratio, the fill weight, the finished acidity. Until that exists there is nothing to be consistent WITH, and "inconsistent" is not even a meaningful complaint. This is the same argument the recipe-to-product page makes from the other end, and this page is what it looks like when it was skipped.
