Twelve years against sixty days: what separates traditional balsamic from balsamic vinegar of Modena

Council Regulation (EC) 813/2000 of 17 April 2000 registered both traditional balsamic vinegars, from Modena and from Reggio Emilia, in a single act. Each is a DOP, the Italian initials for a Protected Designation of Origin (PDO).

Modena's rulebook, from 2000, starts with the grapes: Lambrusco, Ancellotta, Trebbiano, Sauvignon, Sgavetta, Berzemino and Occhio di Gatta, or grapes from DOC vineyards, from the traditional growing area of the province of Modena. The must needs at least 15 saccharometric degrees, the must yield is capped at 70% of the grapes, and muted must (with its fermentation stopped) or must with any additive is banned.

The must is cooked in open vessels over a direct flame for at least 30 minutes at 80 °C (176 °F) or more. It then ages for no less than 12 years, racked between small numbered casks of different woods, and the only addition allowed is the «madre».

As sold, it needs an acidity of at least 4.5 g per 100 g and a density of at least 1.240 at 20 °C. Before bottling, according to the Emilia-Romagna regional government, it goes before «five expert tasters». As for age, Modena's consortium is explicit: the vinegar in the bottle is not 100 or 200 years old; at most, the casks are.

Reggio Emilia's rulebook, amended in 2013 by Implementing Regulation (EU) 1279/2013, uses the same seven grape varieties and the same 12-year minimum. It also names the woods (oak, chestnut, cherry, juniper, mulberry, ash and black locust) and groups the casks into «batterie», batteries, a word Modena's text never uses. As sold, the vinegar needs at least 5 g of acidity per 100 ml, measured by volume rather than by weight as in Modena, and a density of at least 1.200.

The text adds a grading system based on the median score of a panel: below 240 points the vinegar cannot be bottled, 240 to 269 earns an «aragosta» (lobster-red) label, 270 a silver one, and gold requires at least 300 points and at least 25 years. According to the consortium, which counts 61 certified producers, the judging falls to a commission of five master tasters.

Balsamic Vinegar of Modena became an IGP, the Italian initials for a Protected Geographical Indication (PGI), under Regulation (EC) 583/2009 of 3 July 2009. In 2023 Implementing Regulation (EU) 2023/512 lowered the minimum acidity of the «invecchiato» (aged) category from 6% to 5.5% and added formats and isotopic parameters; in 2025 a standard amendment, published in the EU Official Journal on 24 July, created a «Riserva» category.

The current text sets an area for the work, the provinces of Modena and Reggio Emilia, and a list of grape varieties (Lambruschi, Sangiovese, Trebbiani, Albana, Ancellotta, Fortana, Montuni), but it does not say where the grapes must come from. The recipe works by thresholds: cooked or concentrated must at least 20% of the mass, brought to a density of at least 1.240; wine vinegar at least 10%; and an unquantified share of vinegar aged at least 10 years. Caramel is allowed up to 2% of the volume to stabilise the colour; beyond that, «the addition of any other substance is prohibited».

The minimum time in wood is 60 days. After at least 3 years the vinegar may be called «invecchiato», after at least 5 «Riserva», and the minimum density rises with each category: 1.06, 1.15 and 1.25. One oddity in the text: the article that creates the «Riserva» category is the same one that bans the adjective «riserva».

On 4 December 2019, in case C-432/18, the Court of Justice of the European Union spelled out what the IGP registration protects: the name «Aceto Balsamico di Modena» as a whole. The words «aceto» (vinegar) and «balsamico» (balsamic) are not protected, even when combined or translated. According to the Court, «aceto» is a common term and «balsamico» an adjective in common use for a sweet-and-sour vinegar; the Court also notes that the same words appear in the names of the two DOPs.

The court of Bologna went the same way in judgment 2303 of 8 August 2024: according to a summary by a legal publisher, it held that «aceto» and «balsamico» used on condiments are generic terms. On a label, then, the full name is what counts.

«Balsamic condiment» and «glaze» do not correspond to any legal designation, and glaze has no compositional standard. In a test of 11 balsamic creams published on 23 May 2024 by the Italian consumer magazine Il Salvagente, the recurring thickeners were corn starch, xanthan gum and guar, followed by glucose syrup, sugar, concentrated grape juice and caramel E150d. The IGP bans any addition other than caramel, so a thickened cream can contain Balsamic Vinegar of Modena IGP but cannot be sold under that name.

For processed products, article 27 of Regulation (EU) 2024/1143 has applied since 13 May 2024: the IGP name may appear in their name only if they contain no comparable ingredient, the quantity is enough to give an essential characteristic, the percentage is on the label, and the producer notifies the consortium. According to a Qualivita study reported by the farming magazine Terra e Vita in June 2017, 21% of the IGP, about 20 million litres, went into processed products.

The Slovenian rule at the centre of the dispute dates from 2021. Ljubljana notified the draft to the Commission on 2 December 2020 (TRIS procedure 2020/0749/SI), and Italy responded with a detailed opinion. The rules on the quality of vinegar were published in Slovenia's Official Gazette on 9 July 2021, with a one-year transition.

Article 7(b) allows fruit juices and musts in vinegar in general, and article 14 lets such products be called «balzamični kis», balsamic vinegar. The Slovenian government says the term is generic, cites case C-432/18 and points out that the rule mirrors one from 2004.

Italy moved in August 2022: the cabinet was briefed on the 4th, and on the 5th Italy started the procedure between member states under article 259 of the Treaty on the Functioning of the EU. That month, according to the Slovenian public broadcaster RTV SLO, the Commission had not issued a binding opinion; since 2022 there has been no public trace of a reasoned opinion from the Commission or of a case before the Court of Justice.

According to the IGP consortium, an authoritative but interested source, in 2026 Greece, Spain, Slovenia, Cyprus and Hungary still allow «balsamic vinegar» for other products, and the consortium is backing an amendment in the European Parliament.

For the IGP, the figures change with the source. For 2020 the Italian news agency ANSA reported 90 million litres, 92% of it exported. For 2024 the trade publication Great Italian Food Trade, citing the Ismea-Qualivita report, gives 94.4 million litres, up 7.8%, with 93% exported. For 2025 the consortium, on 21 May 2026, spoke of 93-95 million litres a year (roughly 25 million US gallons), over 93% exported to more than 130 countries and 83% of certified output made by members; Il Sole 24 Ore reported a 3% drop in volumes for the same year. An undated data page from the same consortium gives 95-100 million instead, so the two figures do not match.

For Modena's traditional balsamic, Efanews reports 165,653 bottles of 100 ml (3.4 US fl oz) produced in 2024, just over 16,500 litres in all and 16.43% more than the year before: 91,346 of «affinato 12 anni» (refined, 12 years), a consortium term absent from the 2000 rulebook, and 74,307 of extra vecchio, 25 years. We found no volume figures for the Reggio Emilia DOP.

Start with the full name and its initials, DOP or IGP. On the IGP, «Modena» must be printed at least as large as «Aceto» and «Balsamico», and «senza caramello» (no caramel) is banned, even on a vinegar that contains none.

On Modena's traditional balsamic a vintage year is banned, «extra vecchio» (extra old) requires at least 25 years, and qualifiers such as «extra», «riserva» and «classico» are banned: 12 and 25 years are minimums, not birth dates. On the IGP, qualifying terms are banned, numerical ones included, and age is signalled by the categories «invecchiato» and «Riserva».

Then the bottle. Modena's rulebook calls for solid glass, a spherical shape on a rectangular base, a capacity of 10, 20 or 40 cl and a non-reusable, serially numbered seal, and it never names Giugiaro. The single 100 ml format is what the consortium declares, with the 1987 Giugiaro bottle «used by all producers» and a seal number that starts with «A» for the 12-year or «E» for the extra vecchio. In Reggio Emilia the 100 ml bottle is «similar to an upside-down tulip», with sealing wax and an «ABTRE DOP» seal.
