Which white wine option is known for its sweetness and is a part of Barefoot?

The option that represents a white wine known for its sweetness from the Barefoot brand is Moscato. Barefoot Moscato has a distinctively sweet flavor profile, which is characterized by notes of peach, apricot, and nectarines, making it a popular choice among those who prefer sweeter wines.

In contrast, Barefoot Sauvignon Blanc and Barefoot Chardonnay are typically drier, focusing on crisp, fruity flavors rather than the pronounced sweetness found in Moscato. Additionally, Merlot is a red wine, which does not fit the category of white wines being questioned. Therefore, the association of Moscato with sweetness is what makes it the correct choice in this context.
