vinerie (ou vinification) à égouttage (ou écoulement) par gravité
Explanation: Herre is what I found:
"Nous commençons toujours par un égouttage sans pression. (...) Les jus s'écoulent uniquement par gravité vers des cuves situées sous des pressoirs sur deux niveaux differents." http://www.sipp.com/vign7.html
The word "winery" is sometimes translated by "vinerie" but that word seems to be used mainly in Canada or in translations. In France, they seem to use the word "caves a vinification".
See also this site that explains briefly what a "gravity-flow winery" is all about:
"Hamden McIntyre was the architect when the Eshcol winery was built in 1886 and he designed it to use a "gravity flow" system. A horse-drawn winch would bring grapes to the 3rd floor for crushing, and gravity would carry them to the second floor for fermenting and the first floor for aging. The winery was heralded in the local papers of the time as a "model farm". " http://www.trefethen.com/tvwinry.html
