In winemaking, the use of concrete tanks for fermentation and aging of wine is a relatively new and modern technique that has gained popularity in recent years. Concrete tanks are made from a mixture of cement, water, and aggregate such as gravel or sand.
Concrete tanks are an alternative to traditional oak barrels, stainless steel tanks, and other types of containers that are used in winemaking. They offer a number of advantages, such as being more durable, easier to clean, and cheaper than oak barrels. Concrete tanks are also able to maintain a consistent temperature and humidity, which can be beneficial for the fermentation and aging process.
Concrete tanks are neutral in taste, so they don’t impart any oak or other flavors to the wine, unlike barriques. This allows the wine to retain its natural grape variety character. They also allow a better microoxygenation, the small amount of oxygen that enters the concrete walls and is gradually released into the wine can benefit the wine by promoting a more complete fermentation, stabilize the wine, and develop beneficial aromas and flavors.
Concrete tanks are becoming more popular in modern wineries, as they provide a cost-effective and neutral aging option for wines. They are also a more environmentally friendly alternative, as they can be made from sustainable and locally sourced materials, and they last longer than oak barrels. They’re also easy to clean and maintain.
