Night Harvesting in the Vineyards
I am going to have to ask you all to forgive my spelling this week, as my simple grammar skills aren’t too sharp during the busy harvest season. Harvest is probably the busiest time of year for both winery and vineyard employees, but here on the central coast harvesting is typically done at night. For us here at Talley, that typically means starting between 2:00am and 4:00am depending on the amount of grapes to pick. A busy harvesting day can typically last for about an eight hour shift and consist of 10-40 tons of grapes depending on the variety.
The reason we are harvesting at night is driven by quality. Temperature is the key here. With daytime temperatures in the upper 70’s to low 80’s (ideally!!!), there is a lot going on inside the grape cluster itself. Higher temperatures typically lead to more maturation which translates to quicker ripening. By picking at night, when the temperatures are typically in the 50’s, sugar levels remain more stable. The grape clusters themselves are also a little more firm at lower temperatures which keeps them from breaking open while we are picking. Both of these factors give the winery a little more control of the grapes being harvested and help them to avoid any surprises down the road with fermentation. Night harvesting is also beneficial for the harvesting crews. Grape harvesting is pretty labor intensive and very fast paced, so lower temperatures allow for longer hours of picking and a more comfortable environment to be working in. The bees don’t come out until mid morning either… a huge benefit!
So obviously it’s dark at night, how the heck do we pull this off? The full moon is key….
Just kidding.Call it superstition, but here at Talley we do have one block that we like to pick during the full moon every year. In the picture to the left, you can see the moon dropping behind the hills overlooking Rosemary’s pinot noir. For every other night we depend on diesel generator of lights that we tow behind our tractors. With these lights, we are able to light up the vineyard rows just like it is daytime. Our harvesters also wear headlamps to light up any blind spots that may exist. We typically pick four rows at a time per crew of 8 employees. Each harvester carries a yellow picking bin, “FYB” for those that work in the industry (…use your imagination) that they harvest directly into. These bins can hold up to about 40 pounds of grapes, and are then emptied into a larger macro bin towed behind our harvest tractor. Once the bins on the trailer are full, they’re off to the winery for processing.
Harvest here at Talley began this year on August 30, and will most likely end sometime in mid October with the last of our chardonnay being picked. We have currently picked about 60% of our total pinot noir and about 15% of our chardonnay. There’s still a lot of busy nights ahead of us, that’s for sure, but so far so good.
