Wine Spectator School

Class 9: Winegrowing and Winemaking

winemaking: blending, aging and bottling



Blending is one of the finer points of winemaking and there are many reasons winemakers may choose to blend --or to not blend-- their wines.


Because grapes from different vineyards, stages of the harvest and pressings are frequently vinified separately, the small lots of wine contained in each vat or barrel differ slightly.

To achieve consistency, winemakers may choose to combine all the separate lots of the same grape variety into one big blend, or they may carefully select the lots to be blended.

To create a single, more complex wine, an accomplished blender can taste samples from dozens of lots and use one wine's higher acidity to offset another's low acidity, or one's minty note to enhance another's ripe cherry flavors.
