California Flashcards
What is the overall climate in California
Mediterranean
- dry growing season and autumn (can extend the growing season, helpful in cool regions)
Explain the cooling influence of altitude
In California vineyards on high altitude will be higher than the layer of fog. This means, more intense sunlight (although the temperature is lower due to altitude). This can lead to more colour and higher levels of tannins in black grapes
Despite drought, what is another hazard and in which areas?
-Bacterial Pierce Disease, spread by leafhopper insects ‘sharpshooters’
-Southern California, central valley but nowadays also Sonoma & Napa (south)
When the AVA is stated on the label, how many % of grapes should be from that AVA?
85%
When the vineyard is stated on the label, how many % of grapes should be from that vineyard?
95%
