5Nines Distilling uses South Australian-grown and malted Pilsner barley for all its single malt expressions, fermented over seven days before distillation in the distillery's custom-built copper pot still. The Hills Cask is a vatted expression that combines complementary casks including ex-bourbon, Altar wine, and Apera (South Australian sherry-style) barrels to create a well-rounded, approachable dram. The marriage of these cask types delivers a balance of vanilla and caramel from the bourbon wood, dried fruit and spice from the Apera, and vinous character from the Altar wine. Bottled at 45% ABV without chill filtration.

5Nines Distilling is a small-batch single malt producer situated in the Adelaide Hills of South Australia, a cool-climate elevated region whose red clay soils and pronounced diurnal temperature variation suit spirit maturation. Founded in 2016 by David Pearse — a corporate IT architect — and Steven Griguol — a builder and sculptor — the distillery began in David's Adelaide Hills garage before relocating to larger premises on the Adelaide plains in late 2021, enabling seven-days-a-week production. Rather than purchasing equipment from a manufacturer, the pair designed and built their own copper pot still, retaining full control over distillation character. The distillery uses South Australian-grown and malted Pilsner barley across all its single malt expressions.
