Ch. 22-26 – USA Flashcards
History of wine in USA
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
Period of US prohibition
1920 - 1933
First hybrid in USA
Alexander
What does AVA stand for
American Viticultural Areas
Number of AVAs
242
Introducing new AVAs
Proposed via peitition by growers and reviewed by federal government.
Established AVAs with distinctive microclimate can have ‘sub AVAs’ or ‘Nested AVAs’
Does AVA state grapes or winemaking?
no regulations
Appellations of Origin
Defined by political boudaries (county, state)
Min 75% of grapes must come from that appellation
Wine must be fully finished in the state
Labelling options based on origin
AVAs or Appellations of Origin (county, state etc.)
Requirement when wine is labeled with variety
75% of the wine must be from that grape variety
Two or more can be stated if label shows their percentages
Requirement when wine is labeled with appellation of origin
75% of grapes must come from the stated county, state or country of origin.
If the appellation overlaps two states % of each state must be stated.
Vintage can be declared if 85% of wine was produced in stated vintage
Requirement when wine is labeled with AVA
85% of grapes must come from that AVA. The wine must be fermented and fully finished in that AVA. Vintage may be stated if min 95% of wine come from that vintage.
If wine comes entirely from one county, name of county has to appear on the label next to name of AVA (Sonoma county)
General wine business in US
Highest value import sales and global consumption
BUT low consumption per capita (11L)
4th largest producer
BUT 8th in export volume
60% is consumed domestically
Ten largest companies represent more than 90% of US wine sold domestically by volume
three-tier system
Different laws in every state
Gallo, The Wine Group, Constellation Brand
Winemaking history in California
80% of American wine production (250.000 ha)
Grapes introduced by Spanish missionaries
Plantings increased during Gold rush
Wine research in University of California
Overplanting in years before Prohibition

California Climate
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)
Vineyard management
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)
Certification bodies for sustainable viti
The California Sustainable Winegrowing Alliance
Napa Green Rules
Sonoma County Winegrowers
Lodi Rules
Certification organic California
no SO2 added during winemaking
wine from ‘Certified organic grapes’ - so2 can be added.
wine labelled ‘California’ must be:
made entirely from grapes grown in the state
Wine labelled with vineyard name must be:
made from at least 95% grapes grown on that vineyard
Labelling term ‘estate bottled’ can be used when:
vineyards and winery are in the same AVA
