👉 Champagnen is a French term that refers to a type of wine made from grapes that are picked and fermented in oak barrels. This process helps preserve the wine's complexity, color, and flavor. The term "champagnen" likely originated from the use of oak barrels as a fermentation vessel for wine production. The process involves fermenting the juice of grape skins in wood from oak barrels, which adds complexity to the wine and allows it to age better over time.
