27
Describe the Aroya Grande Valley AVA

An east-west orientation of the Southern Coast Ranges formed by plate tectonic shifts. Santa Barbara County
32
Describe the effect of the Transverse Ranges
The western side of the valleys face the Pacific Ocean and funnel in the cooling breezes and fog eastward into the vineyards, lowering temperatures significantly.
33
What are the two most common grape varieties in Santa Barbara County?
Chardonnay and Pinot Noir
34

37
What are two distinguishing features of Sta. Rita Hills AVA
1) Its east-west orientation is framed by hills in the north and south 2) Calcium-rich soils.
38
Why are Grenache and Syrah more commonly planted in Ballard Canyon AVA?
It's further inland and the canyon runs north to south, sheltering the vineyards from much of the cool breezes from the west.
39
A mix of Bordeaux, Rhône and Italian varieties are grown in Los Olivos AVA. Why?
It has warm, sunny days, but without altitude or much fog influence has a relatively low diurnal range
40
Describe Happy Canyon of Santa Barbara AVA (3)
1) Furthest from the Pacific Ocean. 2) The valley shifts orientation to north-south, and blocks the Pacific breezes. 3) Cooling influences come from high altitude sites and exposure to afternoon winds
41
What are five common grape varieties planted in the Central Valley?
1) French Colombard 2) Chardonnay 3) Muscat 4) Zinfandel 5) Merlot
42
What is the Central Valley most known for and why?
Large-scale production due to its flat, fertile plains and high daytime temperatures
43
Describe the climate of Lodi AVA
Hot Mediterranean moderated by cooling afternoon winds from the San Francisco Bay and the Sacramento-San Joaquin Delta
44
How is it possible for coastal influence to travel so far inland to Lodi AVA?
Flat land in the area with breaks between the North and South Coast Ranges means that breezes off the San Fran Bay
45
Describe the viticultural set-up for Lodi AVA
Vineyards are on flatlands of free-draining sandy and clay loam soils
46
How are vines typically trained in Lodi AVA and why?
Cordon-trained and VSP trellised as replacement cane systems would require more labour

Old vine Zinfandel, with some vines considerably over 100 years old

Where are the vineyards of South Coast AVA typically planted and why?
In areas exposed to breezes from the Pacific, though some rely on altitude for temperature relief, as the low latitude means cooling influence is necessary
56
Where is the South Coast AVA?
Extends from the south of Los Angeles to the border with Mexico
