A

41
Q

Which grape is used in Cremant Bourgogne?

A

Aligote

42
Q

Which country has the largest amount of wine grapes by acreage?

A

Spain (~1 million ha)

43
Q

What crop of grapes is normally the first that can harvested for wine and how long until vines produce what are considered quality wine grapes?

A

Three years/six years

44
Q

What are the two viable methods of grapevine propagation?

A

Cloning and field grafting

45
Q

What is considered the ideal latitudes for grape growing?

A

Between 30-50 degrees (in both hemispheres)

46
Q

What is the growth cycle of a grape vine?

A

Dormancy, weeping (when ground is >50 degrees F), budbreak, flowering, fruit set, veraison, harvest (when grapes are at physical/phenolic maturity)

47
Q

How do grapevines propagate?

A

vinifera vines are self propagating (i.e. wind)

48
Q

In general, how long is it from budbreak to harvest?

A

140 - 160 days

49
Q

What is photosynthesis and what is it dependent on?

A

Photosynthesis converts carbon dioxide and water into sugar and is dependent on two things; sunshine and temperature (it slows at temperatures less than 50°F (10°C) or greater than 95°F (35°C). Optimal sugar production takes place on sunny days with temperatures between 70°F and 85°F (20–30°C).

50
Q

What is respiration?

A

Respiration occurs as the plant breaks down sugar and related carbohydrates, releasing their energy for use by the plant. During veraison and at other times when sugar is unavailable, the vine shifts from metabolizing sugar to metabolizing malic acid (as well as trace amounts of other compounds) for energy. Early in their development, grapes are full of malic acid, but later on, as respiration starts to utilize this acid, the acid level in the grapes will be much lower.

51
Q

What is respiration most affected by?

A

Respiration is a continuous process that occurs throughout the growing season, but its rate is affected by temperature. For every 18°F increase in temperature, the rate of respiration doubles. The warmer it is, the faster the plant respires, and the quicker the acid level drops as the vine uses its acid for energy. For this reason, cool nights are usually beneficial for the ripening of grapes,

52
Q

What is transpiration?

A

The process by which water evaporates through openings on the underside of the leaves known as stomata.

53
Q

What are the best weather conditions for transpiration?

A

It is highest under sunny, hot, windy, and dry conditions. The stomata will close if not enough water is brought in through the roots to meet the transpirational demand. Because these openings also control the intake of carbon dioxide, a shutdown of transpiration will also stop photosynthetic activity.

54
Q

How much precipitation do vines need?

A

About 20–30 inches (51–76 cm) of water annually, which they can receive through rainfall, irrigation, or a combination of the two.

55
Q

What two characteristics do all great vineyards have in common?

A
  1. They are not very fertile.

2. Their soils regulate the supply of water to the vine.

56
Q

What is cane pruning?

A

Using cane pruning, the grower will remove all but one or two canes per vine. The remaining canes are attached to a horizontal trellis and trimmed so that each cane has between six and ten nodes (buds).

57
Q

What is spur pruning?

A

Spur (cordon) pruning: Using spur pruning, vines are trained to develop one or more permanent cordons (branches), each of which will support several canes. Annual pruning will cut back the new canes, leaving behind several spurs.

58
Q

What is the Guyot trellis system and what are its benefits?

A

in which one or two canes or cordons from each vine are trained along a wire. Such systems often use a configuration known as vertical shoot positioning (VSP) in which the new year’s shoots and leave are trained upward and braced by trellis wires as they grow,

Benefits of vertical shoot positioning include good air circulation and light exposure as well as ease of use with mechanical harvesters.

59
Q

What are some examples of “divided canopy” trellis systems? What are the benefits?

A

In high vigor sites, a divided canopy—with two or more separate fruiting zones, spaced either horizontally or vertically—may be used to provide more space for the vine to spread out.
Well-known examples of divided canopies include the Geneva Double Curtain, Lyre, and Scott Henry systems.

60
Q

What is another term(s) for bush vines?

A

Head-trained or gobelet style vines

61
Q

What is canopy management? What are some examples?

A

Techniques that alter the position or number of shoots and grape clusters are collectively known as canopy management.
Canopy management techniques employed during the growing season include shoot thinning, shoot positioning, leaf removal, crop thinning, and other procedures intended to optimize fruit quality through the control of vine yield and vigor.
