What month are grapes typically harvested?

The timing of the grape harvest varies by region, depending on the climate and the specific grape varieties. Northern Hemisphere vineyards will harvest grapes from August to November, while Southern Hemisphere vineyards harvest grapes from March to August. Location is the only determining factor for when harvest occurs.

In California's Mediterranean climate type, harvesting occurs between July and October. In tropical regions, harvesting occurs between November and February. Vineyards adjacent to the ocean generally harvest their grapes later than those inland. Similarly, vineyards located on mountainsides will harvest grapes approximately one week later for every 100 meters of elevation increase.

Different grape varieties mature at various speeds. Early varieties such as Concord typically mature in approximately 90 days. Late varieties, such as Cabernet Franc, will take approximately 160 days. This biological clock influences decision-making, regardless of your location.

Watch for patterns in these locations as you work through your harvest plans. Coastal fog will inhibit ripening, while inland heat will accelerate ripening. Elevation adds approximately one week for every 100 meters of elevation gain. Keep a close watch on the local climate records of your vineyard.

Combine regional knowledge with the specific requirements of grape varieties. Coastal Cabernet needs more weeks than inland Concord. Track your particular conditions rather than fixed calendar dates.
