Which GI represents the region of Rutherglen?

The correct answer is Glenrowan GI, which is closely associated with the Rutherglen region, known for its robust wine production, particularly fortified wines like Muscat and Topaque. Glenrowan GI, while a distinct geographic indication, shares a strong historical and stylistic connection with the Rutherglen area, allowing for a recognition of similar vineyard practices and grape varieties.

The other geographic indications—McLaren Vale, Currency Creek, and Riverina—are distinct regions with their own unique climates, soil types, and wine styles. McLaren Vale is renowned for its rich Shiraz and Mediterranean varietals, Currency Creek is known for its cool climate wines including Chardonnay and Sauvignon Blanc, and Riverina is primarily recognized for its large-scale production of bulk wines and renowned for Botrytis dessert wines. None of these regions have the same direct affiliation with the style and heritage of Rutherglen's production as Glenrowan does, highlighting the unique identity that Glenrowan holds in relation to Rutherglen's winemaking culture.
