Label Rules: 85% Rule for Variety, Vintage, and Geographic Indication

In the United States, the Alcohol and Tobacco Tax and Trade Bureau (TTB) administers wine labeling standards under 27 CFR Part 4. The federal rules create a tiered system where the required percentage depends on the type of claim being made. A varietal designation requires only 75% of that grape, while an AVA geographic claim raises the bar to 85%. Vintage claims are most demanding of all: wines using a state or county appellation need 85% from the stated year, but AVA-labeled wines must achieve 95%. Before the 2006 federal rule change, all US vintage claims required 95%, and the revision to 85% for non-AVA wines was intended to align American producers with international standards.

• Varietal claims (e.g., Merlot, Chardonnay): federal minimum is 75% of that variety; appellation of origin must also appear on the label
• AVA geographic claims: at least 85% of grapes must come from the named AVA, and the wine must be fully finished within the state where the AVA is located
• Vintage on non-AVA labels (state or county): 85% from the stated harvest year; vintage on AVA labels: 95% from the stated year
• Vineyard-designated wines: a stricter 95% minimum applies to ensure single-site character is accurately represented

Several US states impose standards that exceed federal minimums. Oregon operates some of the strictest wine labeling regulations in the country. For more than 50 varieties including Pinot Noir, Pinot Gris, Chardonnay, and Pinot Blanc, wines must contain at least 90% of the named variety. Oregon also requires 95% from a stated AVA, compared to the federal 85%. California mandates 100% California-grown grapes for any wine carrying the California state appellation, stricter than the federal 75%, and requires 85% from a named AVA. These elevated standards reflect each state's commitment to terroir expression and consumer confidence.

• Oregon: 90% varietal minimum for most varieties; 18 varieties including Cabernet Sauvignon, Syrah, and Merlot are exempt and follow the federal 75% floor
• Oregon AVA rule: 95% of grapes must come from the stated AVA, compared to the federal standard of 85%
• California state appellation: 100% of grapes must come from within California, stricter than the 75% federal baseline for state-level claims
• California AVA labels: 85% from the named AVA, consistent with federal rules but combined with the 100% California origin requirement for the remaining fruit

The European Union wine labeling framework is built around Regulation (EU) No 1308/2013, supplemented by Commission Delegated Regulation (EU) 2019/33. These rules create a clear distinction between the two tiers of geographic protection. Protected Designation of Origin (PDO) wines, which include France's AOC, Italy's DOC and DOCG, and Spain's DOCa, require that grapes originate exclusively from the defined geographic area, meaning 100% from the region. Protected Geographical Indication (PGI) wines operate under a lighter standard of 85% from the stated area. For both variety and vintage declarations across EU wines, the 85% minimum applies under Regulation 2019/33.

• PDO wines (France AOC, Italy DOC/DOCG, Spain DOCa): 100% of grapes must originate from the defined geographic area, per Regulation (EU) No 1308/2013
• PGI wines (France IGP, Germany Landwein equivalents): at least 85% of grapes must come from the indicated geographic region
• Vintage declarations on EU wines: at least 85% of grapes must have been harvested in the stated year, per Regulation (EU) 2019/33
• Variety declarations on EU wines: at least 85% of the wine must be produced from the stated grape variety under the same delegated regulation

Australia applies the 85% rule uniformly across all three major label claims: geographic indication, grape variety, and vintage year. This standard is enforced through the Label Integrity Program (LIP), a compliance system funded by Australian wineries through a levy on each tonne of grapes crushed. The LIP requires every party in the supply chain to keep meticulous, auditable records tracing vintage, variety, and GI claims from harvest through to bottling. If a single GI such as Barossa Valley or Margaret River appears on a label, at least 85% of the fruit must have been grown within that GI. If less than 85% qualifies, producers must either name a larger encompassing GI or list multiple GIs in descending order of volume.

• Single GI claim: 85% of grapes must originate from the stated geographic indication; the remaining 15% can come from outside with no disclosure required
• Multiple GI claims: if two or three GIs are listed, 95% of the wine must come from those regions combined, with at least 5% from each
• Variety claim: 85% minimum of the stated grape; if a second variety reaches 15% or more of the blend, it must also be declared on the label
• Vintage claim: 85% minimum from the stated harvest year; the Label Integrity Program requires auditable records to support all label claims

One of the most frequent errors among wine students is assuming a single universal 85% rule applies to all label claims across all jurisdictions. In reality, the thresholds differ by claim type, jurisdiction, and appellation level. In the US, the federal varietal minimum is 75%, not 85%. AVA vintage claims require 95%, not 85%. EU PDO wines require 100% geographic origin, while PGI wines require 85%. Oregon raises its varietal bar to 90% for its key varieties. WSET and Court of Master Sommeliers candidates should pay close attention to these distinctions, as exam questions frequently test whether candidates can distinguish between the geographic, varietal, and vintage thresholds within a single jurisdiction.

• US federal varietal minimum is 75%, not 85%; the 85% figure in the US applies specifically to AVA geographic claims
• US vintage rules differ by appellation tier: 85% for state or county appellations, 95% for AVA-designated wines
• EU PDO (AOC, DOC, DOCG) requires 100% geographic origin; the 85% rule applies to PGI wines and to variety and vintage declarations across both tiers
• Oregon's 90% varietal rule applies to over 50 varieties but 18 Bordeaux and Rhône varieties follow the federal 75% baseline, a detail that frequently appears in advanced exam scenarios

Producers must document compliance through verifiable records at every stage of production. In the US, labels require a Certificate of Label Approval (COLA) from the TTB, which involves submitting blending sheets and sourcing documentation. In Australia, the Label Integrity Program obliges every participant in the supply chain, from grower to bottler, to maintain records that can be audited at any point. The EU requires annual verification of PDO and PGI compliance by competent national authorities under Regulation (EU) 2019/34. Violations in the EU result in enforcement actions administered by each member state's regulator, including removal of wines from the market.

• US producers must obtain a TTB Certificate of Label Approval (COLA) before any wine enters commerce; the application requires documentation of varietal, vintage, and geographic sourcing
• Australia's Label Integrity Program is self-funded by the industry via a levy per tonne of grapes crushed; it requires records tracing wine from vineyard through to bottled product
• EU member state authorities conduct annual verification of PDO and PGI compliance under Regulation (EU) 2019/34; enforcement actions including market removal are governed by Regulation (EU) 1308/2013
• Scientific verification tools including isotopic analysis and DNA varietal profiling are used by EU authorities to detect fraud in varietal and geographic labeling claims
