1 point

Which of the following is/ are true about climatic influences? *

1 point

A. On the same latitude, vineyards in higher altitude have a warmer climate

B. Vineyards close to the sea and its currents benefit from a moderating influence

C. Cloud, fog and mist block sunlight to a vineyards, which slows the ripening process because the lack of sunlight slows down photosynthesis

D. Answers B and C only

E. Answers A, B and C

Which of the following are true regarding climatic influences? *

1 point

A. Rivers help warming surrounding vineyards in cool climates and extend the ripening season

B. Cool air from the seas and mountains have a moderating effect (warming or cooling)

C. Mountains can act as barriers to shelter vineyards from clouds, rain and winds, which result in sunny summers, dry long autumns

D. Answers A and B only

E. Answers A, B and C

Which is FALSE about Training and Pruning *

1 point

Training and pruning refer to the human pollination of grape flowers

The purpose of training and pruning is to ensure that a healthy and commercially viable crop of grapes can be harvested successfully every year

Most vines are trained on trellises

Vines are pruned in the winter while they are dormant

Pruning ensures that individual vines retain their required shape

The main objective of a grower is always to maximize yield

Sometimes yield is restricted by law

Yield that are too small may not be commercially viable

Yield that are too high may be diluted in flavors and lower in sugar content

Which is/ are true about Harvest? *

1 point

A. Harvesting too early may mean unripe grapes, high acid, low sugar and herbaceous flavors
