Introduction
Tannat is a grape variety known for its high tannin levels, which can result in a robust and sometimes astringent wine. To soften the harsh tannins and improve the overall balance and mouthfeel of Tannat wines, winemakers often employ oak aging and micro oxygenation techniques. In this report, we will explore how these methods are used to create more approachable and well-rounded Tannat wines.
Oak Aging Process
1. Oak Selection
One of the key factors in softening Tannat wines is the choice of oak barrels for aging. Winemakers typically use French oak barrels, as they impart a more subtle and refined flavor profile compared to American oak. The tight grain of French oak allows for a slower and more controlled extraction of flavors, which can help to soften the tannins in the wine.
2. Aging Duration
The length of time that Tannat wines spend in oak barrels can vary depending on the desired outcome. Generally, wines are aged for 6 months to 2 years in oak before being bottled. Longer aging periods can lead to a more pronounced oak influence and a smoother texture in the wine.
3. Flavor Development
During the oak aging process, Tannat wines undergo a series of chemical reactions that help to soften the tannins and enhance the overall flavor profile. The oak imparts flavors of vanilla, spice, and toast, which can complement the natural fruit characteristics of the wine. These flavors help to round out the wine and create a more complex and balanced final product.
Micro Oxygenation
1. Controlled Oxidation
Micro oxygenation is a process in which controlled amounts of oxygen are introduced to the wine during the aging process. This technique can help to soften the tannins in Tannat wines by promoting polymerization, which binds the tannins together and reduces their astringency. By carefully regulating the amount of oxygen exposure, winemakers can achieve the desired level of softness in the wine.
2. Improved Mouthfeel
In addition to softening the tannins, micro oxygenation can also improve the overall mouthfeel of Tannat wines. By allowing for gradual oxidation, the wine can develop a smoother texture and a more rounded finish. This can enhance the overall drinking experience and make the wine more approachable to a wider range of consumers.
3. Flavor Stability
Micro oxygenation can also help to stabilize the flavors in Tannat wines, preventing oxidation and off-flavors from developing. By carefully monitoring the oxygen levels throughout the aging process, winemakers can ensure that the wine retains its fresh and vibrant fruit characteristics while still benefiting from the softening effects of the technique.
