What distinguishes Rare Rutherglen Grand Muscat?

Rare Rutherglen Grand Muscat is distinguished by its minimum aging requirement of 20 years. This designation reflects the exceptional quality and complexity that comes from extensive aging in barrels, which allows the wine to develop rich flavors and a deep, amber color. The long aging process contributes to the concentration of flavors and aromas, with notes of dried fruits, nuts, and a signature richness typical of Muscat wines from the Rutherglen region in Victoria, Australia. This level of aging enhances the wine's overall structure and character, setting it apart from other classifications of Muscat that have shorter aging periods or different specifications.

The other options suggest varying aging requirements, but none align with the distinctive 20-year minimum that defines Rare Rutherglen Grand Muscat. This extended maturation is what makes it rare and highly regarded among fortified wines.
