The use of oak barrels in French winemaking has long influenced the taste and quality of wines, adding flavors like vanilla, roasting, and spices from the aging process. In recent years, however, some producers have chosen to emphasize more natural and authentic flavors, moving away from the heavily influenced profiles of oak-aged wines. This shift reflects a broader trend in winemaking that values the original characteristics of grapes and their terroir, or the environmental conditions in which they are grown. On the occasion of its 110th anniversary, Champagne Castelnau has introduced HC n°5, a new version of its prestigious cuvée, created by Carine Bailleul, the cellar master. Inspired by the forest, this wine was developed in collaboration with Jérôme Viard, a master cooper from Champagne. This partnership stands in contrast to the current challenges faced by the French cooperage industry, which is undergoing a market shift. Despite this, Bailleul remains committed to the traditional relationship between wine and oak, stating, "The wine and the wood have always been two sides of the same coin. They maintain a fusion relationship, where one enhances the other and vice versa." The HC n°5 cuvée features aromas of wood and smoke from the Argonne forest, along with spicy and chocolate notes from the Verzy forest. These characteristics are further enhanced through a process called double heating. Bailleul used only forty barrels for this cuvée, sourced from the Montagne de Reims, the Champagne-Ardenne Forest, and the Argonne Forest, with varying levels of heating. She explains that this is an experiment, with a maximum of 5,000 to 8,000 bottles produced. "We wanted to establish a dialogue with the trees, to try to perceive the real voice of the forest, which had disappeared in favor of a form of standardization of tastes. For this, we returned to the origins, to the terroir." Jérôme Viard adds that the oak barrels carry the history of the forests they come from, with growth rings and scars indicating past environmental conditions. Both Bailleul and Viard emphasize the importance of time in their work. It takes four years to make a barrel—three for the wood to mature and one for the heating. Additional time is needed for the wine to age inside the barrel and on lees, a process that Bailleul calls "this little extra soul, which cannot be controlled but makes all the difference." Hannelore Chamaux-Rima, the brand's general director, notes that by extending aging periods, the champagne can compete with aged wines. "We want everything, everything immediately, often forgetting that the things that really matter require time," she says. HC n°5, with its golden hue and silver reflections, seems to pay homage to the famous n°5 fragrance created by Ernest Beaux for Coco Chanel in 1921. Like that fragrance, the wine has layers of aroma: woody notes in the top, a soft sweetness in the heart, and candied fruits and spices in the base. This new cuvée not only marks a successful chapter for Champagne Castelnau but also offers hope for the future of oak barrels, not just as decorative items but as integral components in winemaking. HC n°5 will be available starting October 1st at wine shops, in restaurants, and on the online store of Champagne Castelnau.
