Today’s Wine Word: Green Harvest


“Drop crop”… “Green Thinning”… “Green Harvest”… Whatever you like to call it the term is literal and refers to removing green, immature clusters and dropping them on the ground. It may seem a bit obtuse to be removing perfectly viable fruit that isn’t even mature yet, but it’s often done in the name of flavor intensity and it can happen at several times during the growing season.

The first round may be just after flowering and fruitset, which typically happens in mid to late May. Winter pruning and springtime shoot thinning are done with certain yields in mind. If the vines are overly generous on any given year it’s smart to thin out the excess so the rest can ripen properly and be flavorful, not diluted in taste. Continue reading

Today’s Wine Word: Green Harvest


I remember a story about Gil Nickel, the owner of Far Niente winery (sadly, now deceased) walking the vineyard with his vineyard manager, commenting “Pardon me while I step over my profits.”

There are all kinds of reasons to thin out clusters: For the sake of flavor intensity, to assure the grapes will get sweet enough or to prevent crowding… That’s why you see dried clusters on the ground along with the fresh ones that were just thinned. 
But the green harvest is thinning that’s focused on uniformity of ripening. The clusters don’t all ripen at precisely the same rate, so as veraison, the color change, progresses it’s important to get into the vineyard a few times to see if there are clusters lagging behind – not coloring up the way they should – and thin them out. Sometimes the clusters have small “wings” jutting out at the top and they may not ripen as quickly as the main part of the cluster. So, off they come. Continue reading
