Cheese does not sit still while it ages. Wheels start in a humid ripening section, move to a drier zone once the rind has set, and often move again for finishing. With a few hundred wheels across several sections, the questions come quickly: where is batch 2024-087 right now, and what exactly is in section D?
Paper lists hung on the racks soak up moisture, and writing down forty wheel numbers with cold, wet hands rarely happens. Moves get recorded as "B to D, about 40 wheels", which does not help when you need to find every wheel from one production day.
A barcode label on each section and each wheel, plus a phone that records every move, turns the question of where a batch is into a spreadsheet filter.
