Small Batch Sauerkraut

“Small batch” is a worn-out phrase. Here is what it means in a ferment, specifically.

Fermentation is not a recipe with a timer. It moves with temperature, with the cabbage, with the season. A batch in a warm week is ready sooner than the same batch in a cold one. At small scale you handle that by tasting — you pull the batch when it is right rather than when the schedule says. At large scale you cannot taste every tank, so you standardise: tighter temperature control, sometimes a starter culture to force predictability, often pasteurization at the end so the product stops changing entirely.

Glass matters for the same reason. It is a worse container industrially — heavy, breakable, expensive to ship — and a better one for the food, because you can see the ferment and because nothing leaches into a high-acid liquid sitting in it for months.

The practical consequence for you: our jars are not identical. One batch of Classic Caraway is a touch sourer than the last. That is not a defect, it is what the absence of pasteurization looks like in your fridge.
