Ch. 22-26 – USA Flashcards

1
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.

Coast 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 undrstanding vineyard management

Precision viticulture

Skilled Mexican labour

Lack of rainfall - irrigation (monitoring and regulaton of water use by state 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 Gris Sauvignon Blanc Petitie Sirah ```
27
Chardonnay in California
Full spectrum of styles Usually nearer coastal influence or at high altitudes Med(full) bodied styles, peach pineapple, sencondary 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 uneaven ripening Med+ acidity, fresh fruit + jammy notes, blueberry, blackberry American oak usually for maturation (vanilla) White Zinfandel style: - short maceration before cool ferment in steel - med dry, low alcohol, med acidity and body - strawberry, fruit candy
31
Merlot in California
Very popular in 1990s and 2000s Now mainly inexpensive, some premium is done Used in Bordeaux blends

37
Mendocino County
generally lower priced than Napa and Sonoma and used in multiregional blends
38
Anderson Valley AVA
only few miles from Pacific. Day time warm but cold air and fog is funnelled inland Navarro River, giving cold evenings and mornings (less influence more inland - valley is more narrow) Plenty of rain (900-2000mm) monstly in winter and spring Vineyards on slopes, frost can be problem Pinot Noir and Chardonnay (sparkling and still) - fresh styles Also Alsace-styles whites (Gewurz, Riesling, Pinot Gris, Pinot Blanc) Producers: Littorai and Williams Selyem

41
Allexander Valley AVA
Northeast corner of Sonoma County Warm climate cooled in evenings by Pacific air funnelled in from the Petaluma Gap and Russian River Valley to the south. Both valley and slopes (100-750m) - long hours of sunshine - high colour and tannin, altitudes helps with acidity Fertile valley floor, free draining slopes. 800mm rain (mainly winter) Cabernet Sauvignon mainly - full body, ripe flavours, dried, herbs, chocolate Also Chardonnay, Merlot, Zinfandel, Petit Verdot, Malbec Producers: Kendall-Jackson (including Stonestreet Estate) and Seghesio

General conditions in Willamette Valley AVA
only 50 miles from Pacific, Coast Range 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 farming Diverse range of soils
106
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)
107
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

110
Ribbon Ridge AVA
Protected from wind by surrounding ranges consistently warm dry conditions ``` Sedimentary soils (deep but low in nutrients) Moderate water-holding capacity ``` Concentrated ripe grapes
111
Yamhill-Carlton District AVA
Coast Range gives rain shadow. South facing slopes (60-300m), warm free draining sedimentary soils Riper fruit, fuller body, lower acidity
112
Van Duzer Corridor AVA
break in Coast Range funnels in Pacific Ocean winds during the afternoon, cooling the vineyards - can disrupt flowering - helps to retain acidity, slow sugar accumulation while flavours develop - reduces disease pressure Soils are shallow, free-draining, marine sediment loam
113
Eola-Amity Hills AVA
Shallow rocky volcanic basalt over sedimentary soils 75-250m Cooling ocean winds - slower ripening range of aspects and altitudes (regulates how much vineyards are affected by wind)
114
McMinnville AVA
Some sites are protected from wind by Coast Range some are influenced by cool winds from Van Duzer Corridor
115
Southern Oregon AVA general conditions and sub-AVAs
Warmer than Willamette (cooling influence from mountain air and altitude), river breezes. High diurnal range Growing season is dry - irrigation essential (rainfall in winter) Marine sedimentary soils, volcanic (clay - water retention) and alluvial (more free-draining) Dry farmed vineyards are usually planted with Rhone varieties Pinot Noir 40%, Pinot Gris, Syrah, Tempranillo Umpqua Valley AVA and Rogue Valley AVA

119
Walla Walla Valley AVA
continental climate 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
120
Columbia Gorge
Western side - cooler, wetter, Eastern side - warmer, drier Cooling influence - altitude (up to 600m) and winds funneled by the gorge Number of varieties grown
121
Oregon labelling laws
100% grapes must be grown in Oregon (multi-state appellations may follow either state's labelling law but 100% of 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)
