After the destemming (in some cases these steps are done simultaneously) comes the crushing/pressing. This part of wine production consists in extracting the juice from the berries by squeezing them gently until they release their juices. In red wines, the berries are crushed and the skins are left with the must (the initial grape juice) so they absorb the tannins for their rich deep red color. The skins are taken out after fermentation. In the case of white wines, the grapes are squeezes, not crushed, to limit the absorption of tannins which would color the wine. With rosé wine, the process is a mix of both: the skins are left in long enough for the must to gain the color the wine maker wants, and then they're removed. The rest of the process is the same as for white wines
