What is a common trend regarding new oak usage in the Rhone Valley?

The trend of decreasing new oak usage in the Northern Rhône is primarily due to the region's emphasis on producing wines that reflect the terroir and varietal characteristics. The Northern Rhône is known for its iconic varietals like Syrah and Viognier, which benefit from subtle oak influence rather than being dominated by the flavors of new oak. Winemakers are increasingly opting for older barrels or larger formats, such as foudres, that impart less oak flavor while still allowing for oxidative benefits and subtle improvement in texture and complexity. This nuanced approach aligns with the desire to maintain the purity and expression of the fruit, which is prized in the Northern Rhône.

In contrast, while there may be some increase in new oak usage in the Southern Rhône, it is often less pronounced than the Northern Rhône's decreasing trend. The Southern Rhône has a diverse range of varietals and styles, including blends that can handle more oak; however, it is not universally true that new oak usage is increasing across the board. Thus, the shift in oak practices is more clearly defined in the Northern Rhône, making it a definitive trend in that region.
