Balsamic vinegar of Modena
Balsamic vinegar of Modena is a protected geographic indication variety of balsamic vinegar. It is produced according to various recipes. The PGI production regulations leave plenty of leeway, allowing the use of grape must in percentages between 20 and 90% and wine vinegar between 10 and 80%. The use of caramel is allowed, up to 2%. Reading the tag can provide useful information on the ingredients used and the processing methods. Withdrawal and refilling, as used in making traditional balsamic vinegar, are not required; the ingredients, once mixed, must be kept in wood containers for a duration of at least 60 days. If the product is kept there for 3 years or more it is labeled "invecchiato". The balsamic vinegar of Modena gained the PGI label on 3 July 2009. The requirements for the much more expensive PDO Traditional Balsamic Vinegar are different and more restrictive; it must contain only grape must and be aged for at least 12 years.

The standard for ABM is established as part of the PGI definition. Beyond those mentioned in the introduction, additional rules about the process and materials are:- The grape must can only be derived from the following grape cultivars: Lambrusco, Sangiovese, Trebbiano, Albana, Ancellotta, Fortana, Montuni

- Appearance: clear and brilliant liquid with an intense brown color.
- Odor: characteristic, persistent, intense and delicate, pleasantly acetic, with possible woody notes.
- Flavor: sweet and sour, balanced, pleasant, characteristic.

Granting of PGI label
Upon submission of the application by Italy, Germany, and Greece raised the objection that the protection of the expression balsamic vinegar would have strongly damaged their national production, that has been legalized for five years. They emphasized that the words vinegar and balsamic, as generic terms, were not amenable to protection. They made known that they would have voted for the PGI label only in exchange for recognition of their right to use words balsamic vinegar by Italy. Also, France opposed, especially for the fact that the denomination "Balsamic Vinegar of Modena" would not have had a reputation distinct from that of the "Traditional Balsamic Vinegar of Modena", which would mislead the consumer.After three years of disputes, on 3 July 2009, the European Commission put the balsamic vinegar of Modena in the register of protected geographical indications, with unanimous vote—apart from the "technical" abstention of France. Right after the protection of the EU in 2009, Greece tried to use a technical norm of the EU—unaware of the geographical protection procedures—to obtain recognition of the definition of "greek balsamic vinegar", confirming the attractiveness of a market which at the time was worth around 400 million Euros per year.
In 2019, the European Court of Justice reaffirmed that the individual terms of vinegar and balsamic are not protected.
Consortia
In 1993 the Consorzio Tutela Aceto Balsamico di Modena was born, at the initiative of the largest and oldest manufacturers, for the valorization of the product, its defense, and diffusion worldwide. In 1998 the name was changed to Consorzio Aceto Balsamico di Modena, while keeping the statute unchanged. The consortium mark has been used since January 1999.The Consorzio Filiera Aceto Balsamico di Modena name adopted in 2010 from the Consorzio Produzione Certificata Aceto Balsamico di Modena brought together some of the biggest producers.
In 2013 those two Consortia joined to form the Consorzio Tutela Aceto Balsamico di Modena.
Lastly, between the enforcement and promotion bodies, there's the Comitato Produttori Indipendenti Aceto Balsamico di Modena, that together with the other two consortia was the promoter of the recognition request of the PGI by the European Union.
Consortium Profile
The Consorzio Tutela Aceto Balsamico di Modena has produced a simple labeling system to describe the taste and structure of an ABM. The label describes the body of the vinegar in five segments, from the most tangy to the sweetest. Each level comes with specific requirements for density, total dry extract content, and net dry extract content. For vinegars that have been barrel-aged for more than three years, an "aged" label may be added. The labeling system may only be used by producers that participate in the consortium.| Class | Density | Net dry extract | Total dry extract |
| 1 | 1.060-1.089 | 30-50 | 135-220 |
| 2 | 1.090-1.119 | 35-65 | 210-295 |
| 3 | 1.120-1.149 | 40-80 | 285-380 |
| 4 | 1.150-1.249 | 45-115 | 360-690 |
| 5 | > 1.25 | > 60 | > 620 |
Note:, all units in g/L.
Each level is associated with its own sensory profile and recommended uses.
