Ch. 22-26 – USA Flashcards
AVAs
American Viticultural Areas
- no regulations on grapes or winemaking
Designated regions with unique geological or geographical features
Proposed via peitition by growers and reviewed by the TTB.
Areas within an AVA with distinct microclimates or terrain can be ‘sub AVAs’ or ‘Nested AVAs’
Appellations of Origin (US)
Defined by political boudaries (county, state)
Min 75% of grapes must come from that appellation
Wine must be fully finished in that state
Requirement when wine is labeled with variety (US)
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 (US)
75% of grapes must come from the stated county, state or country of origin.
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 finished in that state.
Vintage may be stated if at least 95% of wine comes from that vintage.
General wine business in US
Highest value import sales and highest global consumption
- BUT low consumption per capita
4th largest producer
- BUT 8th in export volume
- majority is consumed domestically
Fifty largest companies represent more than 90% of US wine sold domestically by volume
- Gallo, Constellation Brands
Three-tier system
- different laws in every state
- increasing number of states allow DTC sales
- cellar doors and wine clubs
California Climate
Cold Pacific Ocean
- California current brings cold water from the north
- Upwelling, where cold deep water rises to the surface
Mediterranean, dry seasons
Coast Ranges provide shelter from the ocean (but have some gaps)
- Vineyards without ocean influence are warm
Warm air raises and pulls in cold air from the coast, giving high diurnal range
- reduction of fungal diseases and frost but can be strong enough to close stomata
- Fog forms during afternoons and can last into mornings
- Strong sunshine above fog layer (altitude provides some moderation though)
Vineyard management in California
1990s saw large scale replanting due to phylloxera, Pierce’s disease and better understanding of vineyard management
- greater attention to matching rootstock to environment
- nowadays, focus on precision viticulture
Skilled Mexican labor
- Central Valley is set up for mechanization, which is also becoming more common elsewhere
Irrigation widespread
- drought reducing water supplies
- greater monitoring and regulaton of water use by state
Reduced fungal disease threat from low rainfall and breezes
Pierce’s disease (sharpshooters), Spring frost, wildfires (smoke taint)
Sustainable grape growing is a focus
- Certified organic wine requires ZERO SO2 added, so is uncommon
- “Certified organic grapes” can be used if the grapes are grown organically
wine labelled ‘California’ must be:
made entirely from grapes grown in the state
California 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 in California
vineyards and winery are in the same AVA
Types of growers and producers in California
Many producers buy in grapes to supplement their own production
Many producers act as merchants or grower-merchants
- allows producers to enlarge their portfolio of wines
Also many independent growers
- head-grafting of vines is common to keep up with changing consumer preferences
- grape prices vary based on supply and demand
- prices can be much higher for prestigious vineyards or AVAs
Wineries range from “cult” wines making small volumes to massive conglomerates
Main grape varieties in California
Chardonnay
Cabernet Sauvignon
Pinot Noir
Zinfandel
Merlot
Colombard
Syrah
Pinot Gris
Sauvignon Blanc
Petitie Sirah
Chardonnay in California
Full spectrum of styles
Usually near coastal influence or at high altitudes
Fuller-bodied styles w/ peach, pineapple, notes from oak and malo
Leaner styles (citrus, less oak, reductive aromas from lees contact)
Inexpensive versions made in easy-drinking style with medium acidity, possibly with residual sugar and/or oak alternatives
Cabernet Sauvignon in California
Site is influential
Moderating influence
- fresher style of black fruit, herbal aroma, less body, lower alcohol.
Concentrated wines
- green harvest, long hang times, full body high alcohol
High percentage of new French oak (but less than in the past)
Also blended with Bordeaux varieties
Pinot Noir in California
On relatively cool sites with coastal influence or altitude
Med+ acidity, med body, med alcohol fresh cherry, raspberry
Riper fruit styles
- med to med+ acidity, greater body, black fruit, jammy
Trend towards earlier picking, whole bunch fermentation, and stem inclusion to enhance aromatics and tanning structure
Commonly matured in French oak, with a proportion new
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 ferment in steel
- med dry, low alcohol, med acidity and body
- strawberry, fruit candy
Merlot in California
Very popular in 1990s and 2000s
Much is inexpensive, very ripe and fruity
Some premium Merlot is made, particularly in more moderate climates (like Oak Knoll district)
Used in Bordeaux blends
Colombard in California
neutral white grape
inexpensive wines
blended
‘fruity white’ or ‘dry white’
Syrah in California
Areas with some cooling influence
med (med+) body, med+ acidity and tannin, fresh plum, blackberry, spice
Pinot Gris in California
increasing
dry but fruity style
Peach pear, melon
Sauvignon Blanc in California
fruity style (steel)
Fume Blanc - usually (not necessarily) fermented and matured in oak
North Coast AVA
Encompasses a large number of AVAs (including Napa County, Sonoma County, Mendocino County, Lake County)
Mayacamas Moutains run through it
Mendocino County
cool AVAs close to the coast
- Pinot, Chardonnay
warmer AVAs inland
- Zinfandel, Cabernet, Syrah
- high altitude vineyards can do cool climate grapes
grapes often used in multi-regional blends
