An olive begins to change the instant it is picked. Bruise it, warm it, or simply let it sit, and the oil inside starts down a path that ends in the flat, fusty taste most people think olive oil is supposed to have.
So we work to a clock. Fruit picked in the morning is at the mill by midday and pressed cold within five hours of leaving the tree. The crates are shallow so the weight of the fruit does not crush the layers beneath. The mill sits at the edge of the grove for the same reason: every minute of travel is a minute the oil cannot get back.
Cold pressing is not a marketing word here. The paste never goes above the temperature of the room. You lose a little yield that way, because heat coaxes more oil out of the fruit. You also lose the green, the pepper, and the cut-grass lift that make a young oil worth drinking, so it is not a trade we are willing to make.
The reward for all of it arrives at the end of the line: oil that is cloudy, almost luminous, and tastes of the field it came from an hour ago.
