Quote:
“in the heart of the Napa valley * * * a single driver pilots a 3.65-metre (12 feet) high arch-shaped tractor towards the end of a row [of grapevines]. * * * Underneath, ten pairs of flexible fibreglass rods are swinging back and forth, their amplitude, frequency and spacing specified by the driver. The vibration separates the grapes from the plant, and a conveyor belt brings them to the top of the vehicle. There, they pass over a series of rollers whose spacing lets the berries through while trapping stray stems and leaves. The vines look undisturbed save for their lack of fruit, their naked stems eerily exposed. The machine, made by Pellenc, a French firm, will harvest 20 tonnes of grapes tonight: enough to make 18,000 bottles of wine, and a harvest that would otherwise require 40 workers.
“Of recent advances in this field, the most technically impressive is probably optical sorting. Food companies have long used cameras and image-processing software to separate and discard low-quality products. But the first sorter designed especially for wine was not released until 2007. Made by Pellenc, it looks like an oversize pinball machine. After destemming, the grapes fall onto a vibrating metal plate that separates them, and proceed to a conveyor belt made of 99 thin rubber cords moving at 22kph (14mph). They then pass under a brilliant halogen light, where a digital camera takes a snapshot. In 30 milliseconds, the device compares each berry’s shape, size, and colour with the winemaker’s guidelines, and ‘shoots down’ the rejects with a quick puff of air, making a sound like a typewriter. * * * Pellenc has already sold more than 1,000 of the units, which can cost up to $250,000. * * * France is the undisputed global leader in wine technology. As Mr Merritt notes, the country has a greater demand for mechanisation than America because its agricultural wages are higher.
My comment:
(a) plonk (n; First Known Use 1930):
“chiefly British: cheap or inferior wine”

Watch the video clip:
(A) From 2:03 to 2:17 of the clip, one sees “ten pairs of flexible fibreglass rods” at work--without grapes.
(B) From 3:20 to 3:40, one sees how those rods work--without the frame to obscure the view--on a bunch grapes, to detach individual berries.
(ii) Roger Pellenc founded the Pellenc Group (based in Vaucluse, France) in 1973, who remains a CEO.

(“named after the famous spring, the Fontaine-de-Vaucluse. The name Vaucluse derives from the Latin Vallis Clausis (closed valley)”)
(c) Another grape harvester from another manufacturer, whose brand is “New Holland” Braud.

(The original New Holland Machine Company was founded in 1895 in New Holland, Pennsylvania [in Lancaster County]; Since 1999, New Holland is a brand of CNH Global, which is majority-owned by Fiat Industrial [based in Turin, Italy]; “In the 1980s Fiat acquired Braud, a French company founded in 1870 which introduced the stationary threshers to farmers in Western France in 1895. In 1975 Braud launched his first grape harvester, model 1020”)

Click the icon “Grape harvester.” In the new Web page, the menu within “DETAIL” shows, among others, “PICKING HEAD” which is not helpful.

At 0:44 you will see ten pairs of picking heads (or rods) NOT in action (not moving, that is), while the harvester was rounding the corner.
