Riesling has been grown on the elevated aspects of Eden Valley for over 150 years. Elevated approximately 450 to 550 meters above sea level, the region's cool climate provides ideal conditions for great Riesling fruit to flourish. The spartan soils and rocky terrain deliver distinctively varietal characters that are unique to Eden Valley. Closely cropped and fastidiously managed, the Hewitson source vineyard yields magnificent fruit. Hand picked grapes are low in pH with fantastic acidity and complete flavour development. Following fermentations, Gun Metal is treated to a settling and cold filtration before bottling.
