Wine Grape Variety
The interdependent factors that affect
wine flavor are the variety or varieties of grape used, the location
where the grapes are grown (appellation), the particular seasonal
weather conditions of that appellation (vintage), the treatment of those vineyards
along with the skills of the vineyardist and finally the equipment and techniques used
by the winemaker, as well as her skills in applying them.
The word "varietal" is only used properly as an adjective, never as a noun...1
But among all these factors, grape variety
has the dominant effect on wine flavor.Take any World Famous Vineyard
(or even an entire Appellation), plant it with a variety
other than the existing one and the wine made there would become completely unrecognizable, even if the vineyards were treated
with the same level of care and attention and the wine was also processed by the same hands and methods.
Variety is truly the spice of life, as Paso Man entertainingly explains in this short YouTube segment:
Varietal character, while somewhat predictable, is not precise. Variations occur,
since virtually all vines are propagated by cloning. Some grape
types are more prone to clonal variation than others.
The name of a particular variety, therefore, should be considered a "surname"
for vines that share a genetic history. Grapes can share genetic profiles, yet vary dramatically in fruit color, as well as in flavors and aromas, such as pinot blanc, pinot gris, pinot meunier, pinot noir. Each "family" of varieties
may, in turn, include only a few or very many individual "sibling"
clones, each with its own particular traits and its clonal name or number which may be considered as its "given" name.
One explanation why so many wine drinkers don't expand their choices beyond the usual Chardonnay,
Merlot, or Cabernet Sauvignon, is that they have little experience with the myriad of other wine grapes available. The profiles here describe
some of the history and cultivation characteristics of different wine grape varieties and aromas and flavors typical in the single-variety
wines and blends they produce.

"White" grapes are listed in GREEN,
while "black" (red) grapes are in PURPLE. Not all varieties are listed (not even close to all). Not all listed varieties are yet profiled/linked (underlined). Grapes profiled are limited to those that are of most importance or significance to
American consumers and those approved by the TTB
for use by American wineries. For additional
