Viticulture Flashcards
Understanding how grapes are grown and where, and the impact on style these factors may play.
As grapes ripen, what changes occur?
- the grapes swell with water,
- the sugar level in the grapes increases,
- acidity falls,
- flavors become more ripe,
- the color deepens
How long can a grape vine live?
Several decades or more
How often will a grape vine produce fruit?
In non-tropical climates, grape vines produce fruit once a year.
Describe flowering for a grape vine.

True or False:
Cool climate regions are closer to the equator.
False
Cool climates are closer to the poles, and farther away from the equator.
Which grapes are more often found in cooler climates?
And which are found in warmer climates?
White wine grapes are more common in cooler regions, and black grapes are often found more often in warmer regions.
There are cool climate red grapes and warm climate white grapes, though, so this is not an exclusive rule.
What are cool climate effects on the characteristics of grapes…
Cool climate will typically create wines with lower levels of sugar and higher levels of acidity in the grapes.
And in warmer climates sugars are often higher and acids lower.
Sunlight is more intense in which type of climate?
Typically in warmer climate regions.
What is the act or process of growing grapes called?
