Ribolla Gialla is historically known by what name?

Ribolla Gialla is historically known as Tocai Friulano. This designation stems from the Friuli region in northeastern Italy, where the grape has been cultivated for centuries. The name "Tocai Friulano" was commonly used until recent changes in wine laws and international agreements required the grape to be referred to as Ribolla Gialla to avoid confusion with Hungary's Tokaji wines.

Ribolla Gialla is appreciated for its vibrant acidity and floral aromas, often showcasing notes of green apple, pear, and citrus. Its usage in the production of both still and sparkling wines further emphasizes its versatility and historical significance in Italian winemaking.

The other options characterize different grape varieties that are distinct in flavor profiles, regions, and winemaking traditions, thus highlighting the uniqueness of Ribolla Gialla's identity in the world of wine.
