Bordeaux Blanc is generally considered a dry white wine. However, it's important to note that the level of sweetness can vary depending on the specific producer and vintage. Bordeaux Blanc is typically known for its crisp, refreshing nature and is not typically made in a sweet style like some other white wines such as Riesling or Moscato.
In Bordeaux, the climate and terroir lend themselves to producing wines with good acidity and balance, which contributes to the dry character of Bordeaux Blanc. The grapes used in Bordeaux Blanc are primarily Semillon, Sauvignon Blanc, and Muscadelle, with Sauvignon Blanc being the dominant grape variety. These grapes often have bright, citrus flavors and herbal notes, which further enhance the dry profile of the wine.
Each producer may have their own unique style and approach to winemaking, so it's always a good idea to consult the specific bottle or speak with a knowledgeable wine professional to get a better understanding of the sweetness level of a particular Bordeaux Blanc. Some winemakers may choose to incorporate a small amount of residual sugar to add a touch of perceived sweetness or balance out the acidity, but this is typically done in moderation and does not result in a noticeably sweet wine.
I have had the pleasure of tasting several Bordeaux Blanc wines from different producers, and I can say that the majority of them have been dry, crisp, and refreshing. The wines often showcase vibrant citrus flavors such as lemon, grapefruit, and lime, with some herbal undertones like grass or green bell pepper. These characteristics make Bordeaux Blanc a versatile wine that can be enjoyed on its own or paired with a wide range of foods.
While there may be variations in sweetness levels among different Bordeaux Blanc wines, the general consensus is that it is a dry white wine that offers a delightful combination of acidity, fruitiness, and herbal nuances.
