Question 5

How is the rainfall in Jerez?

Answer 5

Being the coastal region the annual rainfall is high compared with many other Spanish regions, but rainfall in the growing season is limited and it is the albariza soil in the region that ensures the vine can cope.

Question 6

What is albariza soil?

Answer 6

Albariza has a very high chalk content. It provides good drainage but vitally its depth and excellent water holding capacity mean that it can store enough water to sustain the vines during the hot dry summers. The distinctive white colour of the chalky albariza soil is clear to see in some vinyards.

Question 7

What is the technique for retaining water in Jerez?

Answer 7

In order to maximise the amount of water retained by the soil during the autumn and winter, rectangular pits are dug between the rows of vines to trap the water and reduce run-off.

Question 8

When are the pits dug?

Answer 8

This is done once the harvest has finished and the soil is smoothed out again in the spring.
