The RS, or residual sugar, in Chardonnay refers to the amount of sugar that remains in the wine after the fermentation process is complete. This residual sugar can vary from wine to wine and can have a significant impact on the overall taste and style of the Chardonnay.
In most cases, Chardonnay is made in a dry style, meaning that all of the sugar from the grape must is converted into alcohol during fermentation. This results in a wine that has little to no residual sugar. Dry Chardonnay wines are often crisp, refreshing, and have a higher acidity.
However, there are instances where winemakers may intentionally leave behind a small amount of residual sugar in the wine. This can be done for several reasons, such as to balance out the acidity in the wine, add complexity, or enhance the overall mouthfeel. The amount of residual sugar left in the wine can range from just a few grams per liter to several grams per liter, depending on the winemaker's preference.
It's important to note that the presence of residual sugar does not necessarily mean that the wine will taste sweet. The perception of sweetness in wine is influenced by factors such as acidity, tannins, and alcohol content. Even a wine with a small amount of residual sugar can still taste dry if these other elements are well-balanced.
When tasting a Chardonnay, it can be helpful to pay attention to the levels of sweetness and acidity. Wines with higher levels of residual sugar may have a slightly sweeter taste and a softer mouthfeel, while wines with lower levels of residual sugar will have a drier taste and a crisper, more acidic profile. Personal preferences for sweetness levels can vary greatly, so it's always a good idea to experiment with different styles of Chardonnay to find what suits your palate best.
In my experience as a sommelier, I have come across Chardonnays with varying levels of residual sugar. Some of my most memorable experiences have been with Chardonnays that have a touch of sweetness, which can beautifully complement certain food pairings. For example, a slightly off-dry Chardonnay can be a fantastic match for spicy Asian cuisine or dishes with creamy sauces.
