New Insights into Roman Wine Production Techniques

Archaeologists have recently uncovered intriguing details about the methods used in Roman wine production, shedding light on the appearance, scent, and taste of the popular beverage. During the Roman era, winemaking experienced significant technological advancements and a growing understanding of the process, which spread throughout the vast empire.

While classical Roman authors such as Cato, Columella, Horace, and Pliny wrote extensively on the significance of wine in Roman culture, their works also provide valuable insights into winemaking techniques and viticultural practices of the time.

A recent study published in the journal Antiquity focused on Roman clay jars called dolia, which played a crucial role in the production, fermentation, storage, and aging of wine. Researchers Dr. Dimitri Van Limbergen from Ghent University and Dr. Paulina Komar from the University of Warsaw conducted a comparative study between Roman dolia and modern vessels used in contemporary winemaking.

Interestingly, the study drew parallels between Roman wine production and the traditional Georgian method. In Georgia, winemakers use clay vessels known as qvevri for fermentation, resulting in unique colors, aromas, and flavors. The similarity between this ancient Georgian technique and Roman wine production suggests that Roman wines may have shared similarities with contemporary Georgian wines.

The shape of the vessel also played a significant role in the wine’s characteristics. The narrow base of the qvevri, for example, limited the contact of grape solids with the maturing wine, enhancing its longevity and giving it a captivating orange hue highly prized during ancient times.

By burying the dolia in the ground, Roman winemakers were able to exert control over temperature and pH, encouraging the formation of surface yeasts and a compound called sotolon. This imparted a slightly spicy flavor to the wine with hints of toasted bread and walnuts.

In contrast to modern metal containers, clay vessels exhibit porosity, allowing for oxidation throughout the fermentation process. The mineral-rich nature of the clay also introduced a drying sensation in the mouth, a characteristic that seems to have been favored by the Roman palate.

This research suggests that the Romans possessed a deep understanding of winemaking techniques and were able to modify the characteristics of their wines. By adjusting the shape, size, and composition of the dolia, as well as the methods of storage, Roman winemakers exercised significant control over the final product.

Dr. Van Limbergen highlights the value of uncovering these parallels between modern and ancient winemaking, debunking misconceptions about Roman winemaking and revealing commonalities in vinification procedures that have been practiced for millennia.
