...In the Beginning
Wine is simply fermented grape juice. The natural yeast
on the grape skins convert to sugar in the juice to
alcohol. The basic chemistry is simple, but making fine,
complex wines is far more involved and there are
significant differences in how wines are made when
different styles are the goal.
These involve such basics as the right business and of
the grapes when harvested, whether the wine undergoes a
secondary fermentation called malolactic fermentation,
and whether the young wine is aged in new or used oak
barrels and for how long, or whether it is aged in oak
at all.
The notion of fine wine begins with the most basic
decision: what kind of grapes to grow and where to plant
them.
Great wines start in the vineyards. Factors that
influence a wine's health include the soil texture,
drainage, depth and color. Areas which receive lots of
rainfall benefit from rocky soils that drain easily.
Cool areas benefit from soils that collect and hold
heat. Exposures influence how much or how little sun a
vine receives; a northern-facing vineyard receives less
sunlight than a south-facing vineyard. All of these
factors are taken into consideration when producing high
quality wines.
While some grape varieties will flourish in a wide
variety of soils and climates, the fine wine grapes need
fairly specific soils and climactic conditions to excel.
When grapes and soil are properly matched, the resulting
wines reflect the place where they are grown, what the
French terroir. Terroir expresses the interaction of
many factors with the grapevines, temperatures by day
and night, rainfall distribution by season and year,
exposure to the sun, soil acidity, soil depth, soil
composition and proximity to a body of water - basically
anything natural that influences the growth of the vine.
