Q

History of wine in USA

A

4th largest wine producer
80% California
Brought-in wines suffered from local diseases.
Hybrid of Lambrusca and Vinifera (Alexander) was a building block for viticulture in 1800s.
Vinifera grapes did well in New Mexico and California. Growth of vineyards during gold rush.
prohibition in 1920-1933 (Wine for sacramental purposes only).
Grape juice for home winemaking allowed to be sold.
Followed by recession (wine was unaffordable)
1940’ Gallo, Roma Wines emerged - strong brand names connected to Europe (California Burgundy, Pink Chablis)
New Hybrids, better viticulture (more locations for vinifera) in 1970s

Q

California climate

A

Cold Pacific Ocean and Mountain ranges
Mediterranean, dry seasons
Pacific current brings cold water from the north. Vineyards without ocean influence are warm.
Coastal Ranges provide shelter from the ocean (but have some gaps)
Fog forms during afternoons and can last into mornings.
Warm air raises and pulls in cold air from the coast, giving high diurnal range - reduction of fungal diseases but can be strong to close stomata.
Strong sunshine above fog layer (higher altitude but more sun)

Q

Vineyard management

A

1990s large scale replanting after Phylloxera, Pierce’s disease and understanding vineyard management
Precision viticulture
Skilled Mexican labour
Lack of rainfall - irrigation (monitoring and regulation of water use bye Tate representatives)
Reduced fungal disease threat
Pierce’s disease (sharpshooter) threat, Spring frost, wild fires (smoke taint)
Sustainable grape growing (certified organic requires ZERO SO2 added)

Relationship between growers and producers in California
Many producers buy in grapes to supplement their own production Enlarging portfolio of wines Many producers act as merchants or grower-merchants
26
Main grape varieties in California
Chardonnay Cabernet Sauvignon Pinot Noir Zinfandel Merlot Colombard Syrah Pinot Grids Sauvignon Blanc Petitie Sirah
27
Chardonnay in California
Usually nearer coastal influence or at higher altitudes Med(full) bodied styles, peach pineapple, secondary tones from oak and malo Leaner styles (citrus, less oak, reductive aromas from lees contact) Residual sugar on inexpensive versions with oak alternatives
28
Cabernet Sauvignon in California
Site is influential Moderating influence - fresher style of black fruit, herbal aroma, less body, lower alcohol Concentrated - green harvest, long hang times, full body high alcohol. High percentage of new French oak Also blended with Bordeaux varieties
29
Pinot Noir in California
On relatively cool sites with coastal influence Med+ acidity, med body, med alcohol (fresh cherry, raspberry) Riper fruit styles - med - med+ acidity, greater body, black fruit, jammy Some do whole bunch ferment and stem inclusion. Common maturation in partially new French oak
30
Zinfandel
Number of old wines (100y+) Prone to uneven ripening Med+ acidity, fresh fruit + jammy notes, blueberry, blackberry American oak usually for maturation (vanilla) White Zinfandel style: - short maceration before cool fermentation in steel - med dry, low alcohol, med acidity and body - strawberry, fruit candy

107
General condities in Willamette Valley AVA
Only 50 miles from Pacific, Coast Rane from west providing some protection but various parts are affected by cold Pacific winds Coolest and wettest areas of Oregon Warm, dry summers, long hours of sunshine High diurnal range in summer (air raises from warm central Oregon and causes cool coastal air to be pulled inland) Lack of humidity in air and dry growing season - temperatures can rise and fall quickly Legislation prohibits use of water from river to all but longest-established producers - dry warming Diverse range of soils
108
Soils in Willamette Valley AVA and training systems to regulate growth
Fertile loam on valley floors (suited to Pinot Gris) - pinot noir has to be regulated (Scott-Henry training) Higher altitudes - mixture of marine sedimentary soil (sandstone etc.), volcanic basalt and loess (lower in fertility - cordon with VSP)
109
Willamette Valley AVA sub- AVAs
Dundee hills AVA Chehalem Mountains AVA Ribbon Ridge AVA Yamhill-Carlton District AVA Van Duzer Corridor AVA Eola-Amity Hills AVA McMinnville AVA

121
Walla Walla Valley AVA
Continental claimde with hot dry summers nearly 40% Cabernet Sauvignon (then merlot, Syrah) Sub-AVA Rock District of Milton-Freewater - Basalt stones and graveled silt loam - warmth radiated from stones adds ripeness
122
Columbia Gorge (climate sides)
Western side - cooler, wetter Eastern side - warmer, drier cooling influence - altitude (up to 600m) and winds funnelled by the gorge Number of varieties grown
123
Oregon labelling laws
100% grapes must be grown in Oregon (multi-state appellations may follow either state's labelling law but 100% grapes must come from these 2 states) 95% of grapes must come from appellation on the label If variety is stated - min 90% of that grape (remaining 10% does not need to be listed on the label)
