This harvester which uses the same gentle crusher/stemmer we us in our production is technically advanced and made in France. We contracted for 2 nights picking to evaluate whether it was suitable for us. Unfortunately it broke down the first night. The machine, I might add, is a 1/2 million investment.
What we did find, although it required a lot fewer people, it did not pick faster than our hand-picking crews. Harvest machines are essential in large vineyards, there simply are not enough pickers, but for smaller wineries the benefit of passing in front of human eyes, on conveyor belts, before reaching the fermenter is a big plus.
