3. Grape Varieties Flashcards

1
Q

Grapes belong to the genus __________.

A

Vitis.

Within the vitis gens, there are a few dozen species of grapes. But only Vitis Vinifera and Vitis Labrusca are used for making grapes (and Vitis Labrusca is used minimally. Its primary value is for its phylloxera resistant root stock.).

Q

What is the difference between a grape species and grape variety?

A

A species is a scientific grouping of plants (or animals) that are genetically similar, which share a broad set of characteristics, and can produce viable offspring through reproduction. Example: Vinifera

A variety is a subspecies. In grape growing, the subspecies is an identifiable group of the same species that share many characteristics of appearance, flavor, and growth. Example: Chardonnay and Syrah are varieties (or subspecies) of Vinifera.

Q

What is a crossing?

A

A cross, or a crossing, is the offspring between different subspecies within the same species.

Example: Cabernet Sauvignon (cross between Cabernet Franc and Sauvignon Blanc)

Q

What is the difference between a crossing an a hybrid?

A

Crossing = offspring from two parents of the same species.

Hybrid = offspring from parents of different species.

Hybrids typically struggle to develop adequate levels of tannin and can be extremely acidic. They are typically not fertile but may be propagated through cuttings.

Seyval Blanc and Vidal Blanc are popular examples of hybrids.

Q

What is vegetative propogation?

A

When a cutting - or another offshoot - of an existing plant sprouts roots to create a new plant.

Most grape varieties in commercial viticulture are reproduced via vegetative propogation.

Q

What is a mutation?

A

A mutation is a grape that has developed sufficiently distinct characteristics from its parents to be considered a separate variety.

Examples: Pinot Blanc and Pinot Gris are mutations from Pinot Noir and considered commercially distinct varieties.
