As an expert sommelier and brewer, I can confidently say that the shelf life of Chardonnay in the fridge can vary depending on its style and how it has been stored. Chardonnay is a full-bodied white wine that can range from unoaked to heavily oaked, and these factors can affect its longevity.
If you have a bottle of oaked Chardonnay, it typically has more structure and complexity due to the aging process in oak barrels. This style of Chardonnay can last for about 3-5 days in the refrigerator when properly corked. The oak aging helps preserve the wine and keeps it fresh for a longer period. However, I would recommend consuming it within the first few days to fully enjoy its flavors and aromas.
On the other hand, unoaked or lightly oaked Chardonnay tends to have a fresher and crisper profile. These wines are often enjoyed for their vibrant fruit flavors and acidity. When stored in the refrigerator with a cork, this style of Chardonnay can also last for 3-5 days, but it may start to lose some of its freshness and vibrancy after the third day.
It is important to note that once a bottle of Chardonnay is opened, it starts to interact with oxygen, which can lead to oxidation and a change in taste. To minimize this process, make sure to re-cork the bottle tightly and store it upright in the refrigerator. This helps reduce the wine's exposure to oxygen and prolong its freshness.
Personal experiences have shown me that the flavor profile of Chardonnay can change over time, even when stored in the fridge. The fruit flavors may become muted, and the wine can develop a slightly oxidized taste after a few days. Therefore, I would recommend consuming the Chardonnay within the first 2-3 days of opening to fully enjoy its true characteristics.
A full-bodied white wine like Chardonnay can last 3-5 days in the refrigerator when corked, with oaked Chardonnay having a slightly longer shelf life. However, for the best drinking experience, it is advisable to consume the wine within the first few days of opening to fully appreciate its flavors and aromas.
