Which GI is solely labeled as Tasmania GI?

The option labeled as Tasmania is the correct answer because it is the only geographical indication (GI) that is unequivocally designated as "Tasmania." This classification reflects the distinct wine-producing region that has its own unique climate, terroir, and grape varieties.

Tasmania is known for its cool climate, which significantly influences the characteristics of the wines produced there. It is particularly celebrated for high-quality Pinots, Sparkling wines, and Rieslings, arising from its ideal conditions for viticulture. The GI serves to identify and protect the integrity of wine produced in this specific area, allowing consumers to appreciate the inherent qualities attributed to Tasmanian wines.

In contrast, the other options represent different regions within Australia that may produce wine, but they do not have the singular designation of being labeled solely as Tasmania. The Granite Belt and South Burnett are regions located in Queensland, while Pipers River is a sub-region within Tasmania. Thus, they do not fulfill the requirement of being a standalone GI termed "Tasmania."
