The following steps are informative only! They give an idea how wine is made:
plantation (or grafting) of a vine stock
growing of the grape-bunch
harvesting the grapes
de-stemming* and crushing the grapes
alcoholic fermentation of the liquid
maceration*
raking the wine
malolactic fermentation
maturation of the wine
bottling the wine
tasting the wine
* : only for red wine, normally
Must : it is the grape-juice produced by crushing.
Alcoholic fermentation : the juice becomes wine under the natural action of yeast which changes sugar in alcohol.
Maceration : the pomace (skin, pips and stems) impregnate the must giving body and color.
Raking : pomace and must are separated. The must becomes "vin de goutte", the pomace becomes "vin de presse".
Malolactic fermentation : under the action of natural bacteria, the harsh malic acid changes itself in lactic acid supple and stable.
Maturation : the wine is clarified and put in casks/barrels to stabilize and perfects itself.
