Green Harvest (Vendange Verte)
The practice of dropping unripe grape bunches mid-season to reduce yield, concentrating the vine's energy into the remaining bunches for better ripeness and quality.
In depth
Vines have a natural tendency to over-produce — left unchecked, they will develop more grape bunches than they can ripen fully. Green harvest involves physically removing grape bunches when they are small and green (typically around veraison), reducing the total crop. The vine then directs its energy into ripening the remaining bunches more completely.
Green harvest is a quality tool used by premium producers to improve: grape ripeness, flavour concentration, colour intensity (for reds), and overall wine complexity. It is common in prestigious regions like Bordeaux, Burgundy, and Barossa for their premium wines.
The economics are significant: a winemaker who removes 30% of their crop at green harvest produces 30% less wine from the same vineyard — a direct cost. This is why it is primarily used for wines sold at premium prices where the quality improvement justifies the yield loss.
At Level 3, green harvest is discussed alongside other yield-reduction techniques (such as pruning to fewer canes in winter) as tools for quality improvement.

Frequently asked questions
- Does reducing yield always improve wine quality?
- Generally yes, to a point. Lower yields concentrate flavour in the remaining grapes and allow fuller ripening. However, the relationship is not linear — excessively low yields can cause over-ripeness and jammy, unbalanced wines. The ideal yield depends on the variety, climate, and desired style. Green harvest is a tool to correct natural over-production, not an automatic quality guarantee.
