Penfolds Reserve Bin A Chardonnay has evolved into a wine that is now a distinctive, single-region style in its own right, with a contemporary and distinctive Adelaide Hills Chardonnay persona.

All fruit is hand-picked into small bins and then whole-bunch pressed. The juice is incrementally filled to barrel directly from the press and allowed to undergo a natural fermentation, sans inoculation. Every new and seasoned French oak barrique is its own unique 225-litre ferment. Enhanced mouthfeel and complexity is achieved by fermenting on solids, 100% malolactic fermentation (all natural). The Adelaide Hills 2016 growing season commenced under mild and dry conditions. Rainfall was below average throughout winter and dry conditions persisted through spring resulting in early vine growth. Conditions for fruit-set and flowering were favourable and contributed towards above average vintage yields. Rain events during late summer were, for the most part, pre-veraison. Cool February conditions meant that ripening was steady and the slightly early start to vintage was a result of a mild and dry growing season. February and March weather allowed for a steady harvest, favourable flavour development and acid retention.
