In the world of wine, the term “clos” refers to a walled vineyard. These vineyards were enclosed by walls, which served multiple purposes. Firstly, the walls provided protection for the grapes, safeguarding them from theft and ensuring that they remained within the confines of the vineyard. Secondly, the walls could potentially create a microclimate within the clos, influencing the growing conditions for the grapes.
The concept of a clos can be traced back to the vineyards of Cistercian monasteries in France. These monasteries recognized the benefits of enclosing their vineyards, both for practical and spiritual reasons. By protecting their grapes from theft, they could ensure a consistent supply of wine for their religious ceremonies. Additionally, the walls created a sense of separation and seclusion, allowing the monks to focus on their winemaking and contemplative practices.
One of the key advantages of a clos is the potential improvement in the mesoclimate. The walls act as a barrier, shielding the vineyard from external influences such as wind and temperature fluctuations. This can create a more stable and favorable environment for the grapes to grow. The enclosed space can also trap heat, especially in cooler regions, helping to ripen the grapes more effectively.
Furthermore, the walls of a clos can provide additional support for the vines. The grapes can be trained along the walls, allowing them to benefit from the radiant heat stored in the stones during the day. This can contribute to better ripening and flavor development in the grapes.
In my personal experience as a sommelier and brewer, I have encountered wines from clos vineyards that possess a unique character. The combination of the protected growing conditions and the focused attention of the winemakers often results in wines that exhibit a distinct sense of place. These wines can showcase exceptional concentration, complexity, and balance.
It is important to note that not all vineyards are enclosed by walls, and the term “clos” is specific to those that are. While the concept originated in France, it has been adopted in other wine regions around the world. Each clos has its own unique characteristics, influenced by factors such as soil type, grape variety, and climate. Exploring wines from different clos vineyards can be a fascinating journey, allowing one to appreciate the nuances and diversity of the wine world.
To summarize, a clos in wine terms refers to a walled vineyard. These enclosed vineyards were traditionally used by Cistercian monasteries in France and offer benefits such as grape protection and potential improvements in the mesoclimate. Wines from clos vineyards often display a distinct sense of place and can be a delight to explore and appreciate.
