Which of the following wines is described as extra dry and fruity?

The correct wine described as extra dry and fruity is Lamberti. This wine, typically a Prosecco or another sparkling varietal, is crafted to achieve a balance between crisp dryness and fruity notes. Its extra dry classification means it has a slight sweetness that is often perceived as fruitiness, making it appealing to many wine enthusiasts who enjoy a refreshing and vibrant flavor profile. The combination of its dry character and fruity elements creates an enjoyable tasting experience, often characterized by citrus and green apple flavors, which are common in this style of wine.

On the other hand, the other wines listed, while they may also offer enjoyable qualities, do not specifically emphasize the same combination of extra dryness and fruitiness characteristic of Lamberti. Gavi, for instance, is known for its minerality and acidity rather than pronounced fruitiness. Similarly, a Copain white blend may focus on a more complex flavor profile with layers of different notes, and Loimer/Grüner is likely to highlight peppery and herbal characteristics typical of Grüner Veltliner, which might not align with the fruity attribute described.
