Why use concrete tanks for wine?
Concrete tanks offer winemakers numerous advantages. They help reveal the true flavors of the wine. These wine tanks allow a small amount of oxygen to pass through the walls, softening tannins and adding complexity to the wine’s palate. Winemakers choose concrete tanks because they don’t alter the wine’s flavor profile, preserving its natural character. This results in a wine that is vibrant, clear, fruity, and of excellent quality. Many believe that concrete tanks maintain the purity and freshness of the grapes, thus enhancing the final wine’s quality. Key Takeaways Concrete Tanks and Wine Flavor Concrete Tanks Micro-Oxygenation Effects Concrete tanks are crucial to the flavor of wine. Tiny pores in the tank walls allow a small amount of oxygen to enter. This occurs during the winemaking and aging process. This small amount of oxygen softens tannins and enriches the wine’s flavor. Argentine scientists studied Malbec wines aged in concrete egg-shaped tanks. They found that these wines received two to three times more oxygen than wines aged in oak barrels or stainless steel tanks. Therefore, these wines contained more anthocyanins, tannins, and color. These changes resulted in a better palate and a more balanced flavor. The micro-oxygenation in concrete tanks helps wines develop richer
