c. n.


Device which first crushes grapes between rollers, then removes stems by beaters revolving in a cage. 1


Crusher-destemmers are used for bulk processing of grapes during harvest in preparation for pressing or primary fermentation. The crushers utilize a set of aluminum rollers that crush and break the skins to release the juice and allow the breakdown of the remaining pulp. A screw feeder moves the grapes to the rollers to begin crushing, dropping the skins and pulp onto a perforated grid, while a shaft with paddles causes the stems to be separated from the grape clusters which are then expelled to the side of the crusher. The rollers should be adjusted to properly crush and break while avoiding bruising or abrading the skins which would release phenols and excess tanning, thus adding astringency to the must and final product. White grapes are crushed before pressing, while red grapes are crushed for immediate fermentation to maximize yield of tannins and flavors, then pressed after the skins and pulp are broken down by the fermentation process. 2


The crusher-destemmer is the first machine to be found in the winery and it’s located outside of it so the grapes can be easily unloaded. 3
