Label Rules: The 85% Rule for GI, Vintage, and Variety

Wine labeling rules are anchored in consumer protection law. Regulators in the EU, USA, Australia, and New Zealand have each developed frameworks that set minimum thresholds for geographic, varietal, and vintage claims, preventing producers from making misleading statements about a wine's origin or composition. While 85% is the most commonly cited figure, the actual threshold depends on jurisdiction, the type of claim being made, and the level of appellation involved. Understanding these distinctions is critical for anyone sitting a wine certification exam or working in the trade.

• EU PDO wines must use grapes exclusively from the stated geographic area; EU PGI wines require at least 85% from the stated area, with up to 15% permitted from elsewhere within the same member state
• US TTB regulations (27 CFR 4.25) set geographic thresholds at 85% for AVA appellations and 75% for state or county appellations; varietal claims require 75% minimum under 27 CFR 4.23
• Australia's Label Integrity Program applies a uniform 85% rule to GI, vintage, and variety claims, enforced through mandatory record-keeping across the entire supply chain under the Wine Australia Act 2013
• New Zealand's Wine Regulations 2021 codify the 85% rule for all three label claim types: grape variety, vintage year, and area of origin, applying the rule cumulatively for combination claims

Despite broad alignment around 85%, meaningful differences exist between jurisdictions. In the EU, the distinction between PDO and PGI status dramatically changes the geographic sourcing requirement: PDO wines such as Burgundy, Barolo, and Rioja must be made entirely from grapes within the defined production zone, while PGI wines need only 85%. In the USA, the TTB applies stricter vintage rules to AVA-labeled wines than to state-labeled wines. These variations are not arbitrary; they reflect the greater precision and accountability expected of higher-classification appellations.

• EU PDO wines (AOC, DOC, DOCG, etc.) require 100% of grapes from the stated area; EU PGI wines (IGT, Vin de Pays equivalents) require a minimum of 85% from the stated area
• In the USA, a wine labeled with an AVA vintage must contain at least 95% grapes from that calendar year, whereas a state-appellated vintage wine requires only 85%
• Oregon has voluntarily adopted stricter rules than federal TTB minimums: wines labeled 'Oregon' must contain at least 95% Oregon-grown grapes, exceeding the federal 75% state requirement
• New Zealand imposes the 85% rule uniformly across variety, vintage, and GI claims, and specifies that any remaining percentage in a GI-labeled wine must also come from New Zealand

The 85% or 75% varietal threshold is what makes most commercially labeled wines technically blends, even when sold under a single varietal name. The permitted minority component, whether 15% or 25%, gives winemakers meaningful room to add complexity, address vintage variation, or provide structural support without changing the label's key message. This flexibility is used widely and legitimately, and is a core feature of winemaking practice in every major producing country.

• US varietal labeling allows up to 25% of other grapes alongside the named variety, provided the named variety constitutes at least 75% and was grown in the labeled appellation
• EU varietal labeling allows up to 15% of other grapes; if two or more varieties are named, the wine must be composed of 100% of those varieties listed in descending order of proportion
• Australia's 85% varietal rule means up to 15% of the blend may come from other varieties; if two or more varieties are declared, they must appear in descending volumetric order and the second variety must constitute at least 5%
• Champagne is a notable exception in the EU: as a PDO, all grapes must originate from within the Champagne appellation, though blending across permitted varieties and vintages is central to the non-vintage style

Vintage claims on wine labels are governed separately from geographic and varietal claims, and the thresholds vary by jurisdiction. In Australia and New Zealand, 85% of the wine must be from the stated harvest year. In the EU, 85% of grapes must have been harvested in the stated year for both PDO and PGI wines. In the USA, the TTB applies a higher 95% minimum to AVA-appellated wines, reflecting the greater geographic precision of that category, while state and county appellated wines need only 85%. Non-vintage wines, such as Champagne NV, are specifically exempt from vintage declarations.

• EU vintage rule: at least 85% of grapes must have been harvested in the stated calendar year, applicable to both PDO and PGI wines
• US vintage rules under 27 CFR 4.27 are tiered: 95% from the stated year for AVA-labeled wines; 85% from the stated year for state or county appellated wines
• Australia and New Zealand both apply an 85% minimum for vintage declarations, meaning up to 15% of the wine may derive from other harvest years
• Non-vintage wines, particularly Champagne NV blends, intentionally incorporate reserve wines from multiple prior years to maintain a consistent house style, making vintage declaration neither applicable nor desirable

The 85% family of rules establishes a floor for consumer information, not a ceiling. A wine labeled as a single variety, from a specific vintage, and a named region gives the consumer a meaningful assurance that the wine's character is substantially shaped by those stated elements. However, the minority component, up to 15% or even 25% depending on jurisdiction and claim type, need not appear on the front label unless the producer chooses to list it. Premium producers often exceed regulatory requirements by publishing full blend compositions, while back labels may include additional detail voluntarily.

• A New Zealand label reading '2021 Marlborough Sauvignon Blanc' guarantees at least 85% Sauvignon Blanc, from Marlborough, from the 2021 vintage, applied cumulatively
• In the US, a wine labeled 'Napa Valley Cabernet Sauvignon 2022' guarantees at least 85% of grapes from Napa Valley, at least 75% Cabernet Sauvignon, and at least 95% grapes from the 2022 vintage, with each threshold applied independently
• Minority blend components below 10% are typically not required on the front label in most jurisdictions, meaning consumers may not see the full composition without consulting back-label disclosure or producer technical notes
• Australia's LIP requires every party in the supply chain to maintain auditable records for vintage, variety, and GI claims, with penalties including export licence cancellation and fines for non-compliance

The 85% threshold did not emerge from a single global agreement but developed in parallel across major wine-producing nations during the latter half of the twentieth century. The US established vintage dating rules for AVA wines at 95% in the 1970s, later differentiating state appellations at 85% through a 2006 rulemaking. The EU harmonized PGI rules at 85% through reforms culminating in Regulation 1308/2013, which consolidated earlier frameworks. Australia developed the Label Integrity Program as a self-regulatory industry mechanism, later codified under the Wine Australia Act 2013. New Zealand aligned with Australia through shared food standards and formalized its own 85% rules under the Wine Regulations 2006 and subsequently the Wine Regulations 2021.

• The US TTB's 95% vintage rule for AVA wines dates to a 1978 ATF rulemaking (T.D. ATF-53); the separate 85% standard for state and county appellated vintage wines was introduced in 2006 (T.D. TTB-45)
• EU harmonization under Regulation 1308/2013 codified the 85% PGI threshold across all member states, while maintaining the 100% sourcing requirement for PDO wines
• Australia's Label Integrity Program was established under federal legislation and is funded by a levy on crushed grapes, requiring the wine industry to self-fund compliance with mandatory record-keeping
• New Zealand updated its wine labeling regulations in 2021, consolidating the 85% rule for variety, vintage, and area of origin under the Wine Regulations 2021 (Clause 43)
