How old is too old for chardonnay?

Chardonnay can age well, but its optimal drinking window varies by style and region. Generally, most unoaked Chardonnays are best enjoyed within 2-5 years, while oaked or premium versions can age gracefully for 5-10 years or more. Beyond this timeframe, the wine may lose its freshness and fruit character, but some well-structured Chardonnays can still provide enjoyment even after a decade. Ultimately, personal preference plays a significant role in determining when a Chardonnay is "too old."
