2.1: Sherry - The Growing Environment and Grape Growing Flashcards
Where is Jerez located?
Andalusía in southern Spain
What is the latitude of Jerez?
low latitude (36°)
What is the altitude of Jerez?
low altitude (0-90 metres above sea level)
What is the climate of Jerez?
- hot Mediterranean climate
- hot, dry summers
- mild, relatively rainy winters
- influences from the Atlantic Ocean
What does the Atlantic Ocean bring to Jerez?
poniente: cool, damp wind that provides a cooling, humid influence in the summer
Name the 2 influential winds in Jerez.
- poniente (cooling, humid influence in the summer)
2. levante (hot, drying wind)
What is the levante?
a hot, drying wind flowing from the south east from north Africa, can make the climate more arid
What is the effect of the Levante on grapes?
- cause grapes to transpire more quickly, concentrating the sugars
- too much sugar can be a negative because it may become difficult to ferment the wine to dryness, which is particularly problematic for the development of flor yeast
Why is the amount of sunlight in Jerez important? What does this mean for the grapes?
- high number of cloud-free days therefore sunlight hours in the growing season are high
- helping to give fully ripe grapes
- without sufficient shading, grapes can easily become sunburnt
Where must the grapes for Sherry come from?
the delimited area of around 7,000 hectares known as the Zona de Producción or Marco de Jerez
Grapes from the Zona de Producción can be used for what?
- DO Jerez-Xérès-Sherry
- DO Manzanilla - Sanlúcar de Barrameda (or the denomination of origin for Sherry vinegar)
What grape can be grown around Montilla but matured in the Zona de Crianza and still be labelled as DO Jerez-Xérès-Sherry?
Pedro Ximénez (also called PX)
Where is Montilla?
within Andalusía, in the mountains above Malaga, but outside the Zona de Producción
What are the 2 parts of the Zona de Producción?
- Jerez Superior
2. Jerez Zona
What is the Jerez Superior known for?
thought to be made up of the better vineyard sites, all located on albariza soil
How much of the plantings does Jerez Superior account for?
over 90% of the plantings
How are the vineyards of Jerez divided?
smaller delimited areas called pagos
What is believed of the pagos?
each is thought to produce wines with different characteristics than the others, a function of factors such as aspect, location, small differences in soil etc.
What is the key soil?
albariza
What type of soil is albariza?
mixture of limestone, silica and clay
What does the clay mean for the soil?
albariza is very effective at retaining and gradually releasing water from winter rainfall, vital in a region that is very dry during the growing season
Why is albariza helpful in reducing evaporation from the soil surface?
forms a crust when dry
What effect does the soil have on planting density compared to other hot regions of Spain?
- high ability to retain water
- higher planting densities and yields are possible in Jerez than in other regions in Spain with hot, dry climates (where low-density bush vines are required if irrigation is not used)
Why are higher yields possible with Sherry?
- grapes do not need to have the same concentration of flavours
- most of the flavour comes through the maturation process
What effect does the color of the soil have?
light colour of the albariza soil also means that it reflects light back into the vine canopy aiding the ripening of the grapes
