Traditional Balsamic Vinegar of Reggio Emilia: How It Is Made and What to Look For

Traditional Balsamic Vinegar of Reggio Emilia DOP is one of two protected designation products made in Emilia-Romagna — the other being Traditional Balsamic Vinegar of Modena DOP. Both are made from cooked grape must aged in a succession of wooden barrels for a minimum of 12 years. Both are entirely different from the commercial balsamic vinegar sold in supermarkets worldwide. And despite coming from neighbouring provinces, the two are officially distinct products with different labelling systems and different bottle shapes.

Reggio Emilia vs Modena: What Is the Difference?

The two DOP products obtained protected status in 2000 and are regulated separately. The production method is essentially the same — cooked grape must, natural fermentation, long barrel aging. The differences are in the labelling and the bottle:

Reggio Emilia uses a colour-coded label system:

• Red label — aged a minimum of 12 years
• Silver label — aged a minimum of 18 years
• Gold label — aged 25 years or more (extravecchio)

The Reggio Emilia DOP bottle is shaped like an inverted tulip. Modena uses a drop-shaped white crystalline glass bottle with a square base. These shapes are legally specified — any product sold in a different container is not the DOP product.

Modena uses a cap colour system (white = 12 years, gold = 25+) rather than label colours. Both systems serve the same purpose: giving the buyer a clear indication of the minimum aging period without needing to read small print.

How It Is Made

Production begins in autumn with the grape harvest. Permitted grape varieties include Trebbiano, Lambrusco, Ancellotta, Malvasia, Sauvignon, and Montuni. The freshly pressed juice — the mosto — is cooked in open copper cauldrons over a direct flame for a full day at low heat. The water evaporates, the sugars concentrate, and the liquid reduces significantly in volume. This cooked must is the starting point for everything that follows.

The cooked must then undergoes natural fermentation — yeasts convert the sugars to alcohol — followed by acidification, as acetic acid bacteria convert the alcohol to acetic acid. The resulting liquid enters the batteria: a series of barrels of progressively smaller sizes, made from different woods. A traditional Reggio Emilia batteria typically runs five barrels: 50, 40, 30, 20, and 15 litres. Wood types vary by producer but commonly include oak, cherry, mulberry, chestnut, and juniper — each wood contributing different flavour compounds to the vinegar over the years.

Once a year, in late autumn or early spring, the producer carries out the rincalzo — transferring vinegar from each barrel into the next smallest one, and topping up the largest barrel with new cooked must. The smallest barrel is the one from which the finished vinegar is eventually drawn. The minimum time before any product can leave the smallest barrel and be presented for DOP certification is 12 years. The extravecchio gold label requires 25 years of this process.

The acetaia — the vinegar cellar — is traditionally located in the attic of the farmhouse. This is not an accident of space: the extreme temperature swings between the Emilian summer (hot, humid, sometimes reaching 35°C) and winter (cold, sometimes below freezing) are considered essential to the development of the vinegar. The heat drives evaporation and concentration; the cold causes the vinegar to rest. Producers who have moved the acetaia to temperature-controlled environments report different — and not necessarily better — results.

The Family Tradition: A Batteria for Every Daughter

In the families of the Reggio Emilia hills, a new batteria of barrels was traditionally started at the birth of each daughter. The barrels aged alongside the child; by the time she married, the batteria formed part of her dowry. This tradition — still observed in some families — reflects the status of the vinegar as both a luxury commodity and an heirloom. Each batteria in a family acetaia belongs to a different member and is considered that person’s own, even when housed under the same roof and tended by the same hands.

Tenuta Rampata: A Producer in Montecchio Emilia

Tenuta Rampata takes its name from La Rampeda — a local dialect term for the sloping land that climbs toward the hills above. The estate sits on the banks of the Enza river in Montecchio Emilia, a small town west of Reggio Emilia. The farm grows Malvasia, Trebbiano, Ancellotta, Grasparossa, and several Lambrusco varieties, producing both wine and traditional balsamic vinegar across four generations of the same family.

The connection between the land, the grape varieties, and the vinegar is direct: the grapes that go into the cooked must are grown in the same vineyards that have produced wine here for over a century. The estate received international attention when a bottle of their traditional balsamic was included in a gift to the White House — a recognition of the product’s standing as one of Italy’s genuinely irreplaceable food specialities.

How to Buy and Use It

The DOP product is sold in 100ml bottles only — the legally defined quantity. Prices reflect the ageing time: a red label (12 years) typically starts around €35–50 for 100ml; gold label (25+ years) can reach €100–150 or more. Any bottle sold at a supermarket price point is not the DOP product and is instead a commercial balsamic condiment, which has its own market but is a fundamentally different thing.

Use it in drops, not splashes. A few drops over aged Parmigiano Reggiano is the most traditional pairing. It works equally well over strawberries, grilled meats, risotto, or — at its most concentrated — eaten alone from a spoon as a digestive. The older the vinegar, the thicker and sweeter it becomes; a 25-year gold label has the consistency of a syrup and a complexity that develops over several minutes on the palate.

To visit an acetaia and taste across ages, the area around Reggio Emilia offers producer visits by appointment. Our Foodies’ Delight food tour includes a visit to a traditional balsamic producer, with tastings across the age range and the chance to see the batteria and acetaia in person.
