Grosset produces wines from Clare Valley in South Australia's Mount Lofty Ranges. The winery's portfolio centers on Riesling, a variety that thrives in the region's cool climate and limestone soils. The G110 Riesling, a single-vineyard expression, demonstrates the precision and mineral intensity the region is known for. Apiana, a blend of Fiano and Sémillon, shows the winery's willingness to explore Mediterranean and classic Australian white varieties alongside traditional Germanic grapes. Springvale Riesling rounds out the core range. These wines have been assessed by Decanter, Wine Advocate, Wine Enthusiast, Wine Spectator, and Falstaff. Clare Valley's continental conditions—warm days, cool nights, and low rainfall—create the conditions for high-acid, age-worthy whites with distinctive character.
