High-speed de-budding (ébourgeonnage).

In order to keep the quality of wine high (and to comply with the AOC), these vineyards are obliged to achieve certain maximum yields (i.e. how many grapes each vine can produce) and so each year the vines have to undergo de-budding. This also has the additional positive effect of spacing out the growth so that each of the bunches of grapes gets better exposure to sunlight.
