The vineyard owner watched one number on his phone the whole time we cleaned
We picked up a vineyard as a client last spring, mostly the tasting room and the event barn, standard stuff. Then in September they asked us to come at six in the morning ahead of a big weekend and I went out myself because two of my guys were down.
The owner was already out there. Not in the building, out in the rows, with a plastic cup and a little handheld thing he was squeezing grapes into. He'd walk twenty feet, pick one, squeeze, look at the number, write it down. I said good morning and he said twenty two four like I'd asked him a question.
He explained it later while I was doing the floors. The number is sugar in the grapes, and he's been tracking it every morning for two weeks. The picking crew is booked for Thursday. If the sugar comes up too fast he needs them Tuesday, and the crew is booked at three other places that week. If it rains before he picks, the berries take on water and the number goes backwards and everything he planned is off.
He'd already moved the crew twice. Said he does it every year and every year it feels like the first time.
I've run a service business for a while and I thought I understood weather risk. Weather risk to me is we don't wash windows today. His whole year lands in about a nine day window and he doesn't get to pick which nine days.
