Bonarda wine can have varying levels of sweetness depending on the winemaking process and the specific style of the wine. Some Bonarda wines are indeed sweet, while others can be dry or off-dry. It's important to note that Bonarda is a grape variety that is grown in different regions around the world, and the style of the wine can vary based on the winemaker's preference and the terroir in which the grapes are grown.
In general, Bonarda wines tend to have a medium to high level of acidity, which can help balance out any sweetness in the wine. The sweetness in Bonarda wines can come from residual sugar that is left in the wine after fermentation, or it can be the result of a winemaking technique called late harvest, where the grapes are left on the vine for an extended period of time to allow for increased sugar concentration.
I have had the pleasure of tasting various Bonarda wines throughout my career as a sommelier, and the sweetness levels have varied greatly. Some Bonarda wines have been noticeably sweet, with flavors of ripe red fruits and a touch of residual sugar on the palate. These wines are often enjoyed as dessert wines or paired with sweet dishes like chocolate or fruit-based desserts.
On the other hand, I have also encountered Bonarda wines that are completely dry or off-dry, with no perceptible sweetness. These wines tend to showcase the natural fruit flavors of the Bonarda grape, with notes of blackberry, cherry, and plum, along with a medium to full-bodied mouthfeel and a moderate level of tannins.
It's important to remember that sweetness is just one aspect of a wine's profile, and there are many other factors to consider when evaluating a Bonarda wine. The acidity, tannins, fruit flavors, and overall balance of the wine are all important components that contribute to its overall character and enjoyment.
Bonarda wine can be sweet, but it can also be dry or off-dry depending on the winemaking process and the style of the wine. It's always a good idea to check the label or consult with a knowledgeable sommelier or wine expert to determine the sweetness level of a specific Bonarda wine before making a purchase or deciding on food pairings.
