Chardonnay is one of the most popular white wines in the world, and for good reason. Its crisp taste and delicious notes of vanilla, apple, and tropical fruits make it one of life’s great pleasures. Chardonnay is also one of the few white wines that can be aged. While many white wines lose their flavor after two years in the bottle, Chardonnay can keep improving for five to eight years. Many winemakers carefully age Chardonnay in oak barrels. Over time, the oak imparts toasty, buttery flavors to the wine.
