“Somebody else is taking the readings now.”
Six in the morning, one person, every tank. Gravity, temperature, pressure, a look at the krausen. The numbers that tell you what every beer in the building is doing — and they end up in a notebook in somebody's back pocket.
Readings go in from a phone at the tank — gravity, temperature, pH if you want it — and each one carries the name of whoever took it, from their login.
Someone enters 1.012 where they meant 1.021. Both believable, which is why nobody catches it, and why the beer nearly gets crashed three days early. You fix it, and the first number stays on the record beside the correction. Nothing you write down quietly goes away.
No signal back between the tanks? The reading waits on the phone and arrives when it reconnects.
