Heggies operates in Eden Valley, the cool-climate pocket of the Barossa region in South Australia. The winery focuses on Riesling, particularly botrytis-affected expressions that capture the region's capacity for noble rot development. The Reserve 242 Botrytis Riesling and Botrytis Riesling represent the core of the portfolio, wines that have drawn assessment from Wine Spectator, Wine Advocate, Wine Enthusiast, and Falstaff. A Reserve Chardonnay rounds out the lineup. Eden Valley's elevation and diurnal temperature swing create conditions suited to aromatic white varieties with structure and aging potential—conditions that shape the character of these releases.
