Brix
Sugar, the number every grower watches.
One number, watched daily
Brix is the measure of sugar in the juice, and sugar is the future alcohol. Every grower lives and dies by this number in the last month.
The scale
18° too early, thin, green 21–22° our target for pinot 24°+ overripe, hot, jammy reading refractometer, in the field
Why we wait
Pick too soon and you get tart, thin wine. Too late and it's jam. The whole craft is knowing the one morning to pick.
