Traditional Roots of Winemaking Containers

The rich history of winemaking is marked by a delicate balance between tradition and progress, particularly in the selection of raw materials for containers used in the fermentation and aging of wine. These vessels, integral to the winemaking process, have evolved over centuries, embodying the cultural and technological advancements of different civilizations.

Stainless steel tanks provide an airtight environment, minimizing oxygen exposure and preserving the freshness of the wine. 

Ancient Origins: From Kvevri to Wooden Barrels

The necessity of containers for transforming grapes into wine and facilitating its transportation dates back to ancient times. Georgia’s Kvevri, terracotta vessels buried underground, played a crucial role in the birth of winemaking. Meanwhile, the Greeks and Romans utilized vessels for the transportation of wine, contributing to the dissemination of vinicultural practices in the Mediterranean. The Celts, on the other hand, introduced wooden barrels, crafted from diverse wood types, for both the transport and storage of wine. This marked the widespread adoption of wooden barrels throughout Europe, influencing winemaking and aging methods.

Modern Palette: Steel, Concrete, Wood, and Terracotta

In contemporary winemaking, a diverse array of materials shapes the containers that house the alchemical transformation of grapes into wine. Steel, concrete, wood, and terracotta stand as the pillars of modern winemaking vessels, each imparting distinct characteristics to the evolving wine. From the robust reliability of steel to the nuanced influence of wood, winemakers today navigate a spectrum of materials, each contributing to the unique flavor profiles and aging processes of wines across the globe.

Stainless Steel Precision: Aromatic Preservation and Controlled Fermentation

Stainless wine tank plays a dual role in winemaking, serving both as vessel for fermentation and as storage unit for aging. These containers, equipped with a fluid-circulating cavity and electrically controlled temperature regulation, hold a pivotal position in maintaining the freshness of wine aromas. The highly resistant nature of stainless steel ensures longevity, creating a reductive environment devoid of oxygen. Its versatility extends to different shapes and capacities, offering winemakers a reliable tool for shaping the aromatic expression of wines.

Cement’s Resurgence: Insulation and Temperature Consistency

In a surprising comeback, cement containers are gaining favor for their ability to shield wine from external influences without imparting additional aromas. Cement’s thermal inertia makes it adaptable to fluctuating temperatures throughout the seasons, although it demands more meticulous care and maintenance compared to its steel counterparts. The reintegration of cement vessels underscores its unique attributes in providing insulation and stability during the winemaking process.

Fired Clay Varieties: Terracotta, Ceramic, Stoneware

Containers crafted from fired clay, including terracotta, ceramic, and stoneware, offer a spectrum of options with distinct effects on wine. The firing temperature influences container porosity, granting terracotta a micro-oxygenation akin to wood, while stoneware ensures an oxygen-free environment. Aromas remain untouched, and new amphoras may introduce earthy nuances. The choice among these fired clay options allows winemakers to fine-tune the impact of the container on the evolving characteristics of the wine.

Wooden Elegance: Porosity, Oxygen Exchange, and Bouquet Enhancement

Wooden containers, especially large-capacity barrels like 500-liter tonneaux, 225-liter barriques (Bordeaux containers), or 228-liter Burgundy containers (pi├Ęces), hold a distinctive role in winemaking. The porosity of the wood influences the speed of evolutionary processes, with smaller barrels facilitating faster changes. Beyond promoting oxygen exchange, wood imparts a significant impact on the wine’s bouquet, introducing hints of vanilla, coconut, walnut, and toasting. The interaction between ellagitannins in wood and wine contributes to the wine’s structure, reducing the perception of astringency and adding a layer of complexity to its taste profile.
