Wine Label Rules: 75% Variety, 85% AVA, 95% Vintage

The Alcohol and Tobacco Tax and Trade Bureau (TTB) sets US wine labeling rules under 27 CFR Part 4. A wine labeled with a single grape variety must contain at least 75% of that grape, with all of the qualifying percentage grown in the labeled appellation of origin. This means a "Napa Valley Cabernet Sauvignon" needs 75% Cabernet Sauvignon, all of it from Napa Valley. The remaining 25% can be any other grape from anywhere. This flexibility is why many Napa Cabernets contain 5 to 15% Merlot, Cabernet Franc, or Petit Verdot for blending complexity without any mention of those grapes on the label. For Vitis labrusca varieties like Concord, the minimum drops to 51%. Geographic sourcing is tiered: a named AVA requires 85% of grapes from within its boundaries, while a state or county designation requires only 75%. Vintage rules mirror the geographic logic: an AVA-designated wine must source 95% from the stated harvest year, while a state or county wine needs only 85%.

• Varietal minimum: 75% of the named Vitis vinifera grape (51% for labrusca varieties like Concord and Catawba)
• AVA sourcing: 85% of grapes from the named American Viticultural Area. Wine must be fully finished in the state(s) containing the AVA
• State or county sourcing: 75% from the named state or county. Wine must be fully finished in the state (or adjacent state for state appellations)
• Vintage with AVA: 95% from the stated harvest year. Vintage with state/county: 85% from the stated harvest year

A persistent misconception holds that US wines need 85% of the stated variety for export. The US has no such rule. The 85% figure is the European Union's import requirement: all wines sold in the EU must meet EU labeling standards, which require 85% minimum for varietal claims on PDO and PGI wines. When a US producer exports to France or Germany, they must satisfy EU regulations on arrival, not US regulations on departure. Some US producers voluntarily exceed the 75% threshold and use 85% or higher across all production to maintain a single standard for domestic and export markets. But this is a business decision, not a legal requirement under TTB rules. The US-EU Wine Trade Agreement governs mutual recognition of winemaking practices and labeling terms but does not change either party's fundamental percentage thresholds.

• US domestic law requires 75% for varietal labeling. There is no federal export threshold
• The EU requires 85% varietal minimum for all wines sold within EU borders, including imports from the US
• Some US producers use 85%+ across all production for operational simplicity, avoiding separate domestic and export cuvees
• The US-EU Wine Trade Agreement covers winemaking practice recognition but does not alter percentage requirements on either side

The EU applies a uniform 85% minimum for both grape variety and vintage claims on wines carrying a Protected Designation of Origin (PDO) or Protected Geographical Indication (PGI). France's AOC, Italy's DOC and DOCG, Spain's DOCa, and Portugal's DOC all map to the EU PDO category. If two or more varieties appear on the label, the wine must be made entirely from those listed grapes, shown in descending order of proportion. Vintage claims are only permitted on PDO and PGI wines; wines without a geographical indication cannot carry a vintage date at all. Since December 2023, new EU regulations (Regulation 2021/2117) require ingredient lists and nutritional declarations on labels for wines produced from the 2024 harvest onward, though the varietal and vintage percentage rules remain unchanged.

• PDO wines: 85% variety minimum, 85% vintage minimum, 100% geographic sourcing from the designated area
• PGI wines: 85% variety minimum, 85% vintage minimum, at least 85% geographic sourcing from the designated area
• Multi-variety labels: 100% of the wine must come from the listed varieties, in descending order of proportion
• No vintage dating permitted on wines without a geographical indication (formerly classified as table wine)

Australia applies a consistent 85% threshold across all three label claims: variety, vintage, and geographical indication (GI). This is often called the "85/85/85 rule." If a label names a grape, 85% must be that grape. If it states a year, 85% from that harvest. If it names a GI, 85% from that region. The Label Integrity Program (LIP), established under the Wine Australia Act 2013, requires every participant in the supply chain to maintain auditable records for seven years verifying these claims. Non-compliance can result in export license cancellation. New Zealand follows the same 85% standard for variety, vintage, and region of origin, making the Australasian rules simpler and more consistent than the US tiered system.

• Australia: 85% for variety, vintage, and GI. Enforced by the Label Integrity Program with mandatory seven-year record-keeping
• New Zealand: 85% for variety, vintage, and region of origin, matching Australia's standard
• Both countries require multi-variety labels to list grapes in descending order of proportion
• The 85% GI rule applies to subregions, regions, and zones but not to "Australia" as a country-level designation

Oregon state law (OAR 845-010-0905) imposes the strictest wine labeling rules in the United States. Most varietal wines must contain at least 90% of the named grape, 15 percentage points above the federal floor. Oregon also requires 100% of grapes from Oregon and 95% from the named AVA or county. However, 18 traditionally blended varieties are exempted and may follow the federal 75% rule: Cabernet Sauvignon, Cabernet Franc, Merlot, Syrah, Grenache, Mourvedre, Petit Verdot, Malbec, Carmenere, Petite Sirah, Sangiovese, Tempranillo, Tannat, Zinfandel, Sauvignon Blanc, Semillon, Marsanne, and Roussanne. This means an Oregon Pinot Noir must be at least 90% Pinot Noir, but an Oregon Cabernet Sauvignon needs only 75%. Washington State largely follows TTB federal guidelines.

• 90% varietal minimum for most grapes including Pinot Noir, Chardonnay, and Riesling
• 18 traditionally blended varieties exempted at 75% (Cabernet Sauvignon, Syrah, Grenache, Merlot, and others)
• 100% Oregon origin required for any Oregon appellation claim
• 95% from the named AVA or county, compared to 85% under federal rules

These rules create a hierarchy of information quality. A wine labeled "California Cabernet Sauvignon" could contain 25% of any other grape from anywhere in the state. A wine labeled "Napa Valley Cabernet Sauvignon 2022" guarantees at least 75% Cabernet, 85% from within the Napa Valley AVA, and 95% from the 2022 harvest. Geographic specificity is a genuine quality signal: narrower appellations enforce stricter sourcing. A "Rutherford" designation (an AVA within Napa Valley) guarantees the same 85% sourcing but from a much smaller, more specific area. Non-vintage wines (common in Champagne, Cava, and fortified styles) bypass vintage rules entirely. Blended wines with no stated variety must meet no percentage threshold but cannot use a varietal name, which is why they carry proprietary names like Opus One or The Prisoner.

• Broader geography means more flexibility: "California" requires 75% in-state sourcing vs. 85% for a named AVA
• Vintage plus AVA is the most demanding US combination: 95% from the stated year AND 85% from the named area
• Non-vintage wines deliberately skip vintage rules, allowing blending across multiple harvest years for consistency
• Proprietary-named blends (Opus One, The Prisoner, Insignia) avoid varietal labeling rules entirely by not claiming a grape on the label
