Since it's inaugural release in 1993, Grosset has made a powerful statement about the potential of Piccadilly Valley, an Adelaide Hills subregion that's so cool, it is often considered marginal for wine. It's an area that takes time to understand but the wines can be exquisite. Piccadilly is deliberately restrained. Succulent white peach, melon and grapefruit characters create a mineral, focused wine that's fresh and refined.

Followers of fine Chardonnay will notice a consistency in style amongst the most recent vintages of Grosset Piccadilly. Jeff sees these as a return to the clearly defined style that he made in the 1990s, leaner and finer, tighter and slightly lower in alcohol. Often shy and restrained on release, needing patience and time to reveal themselves, the Piccadilly Chardonnays come into their own by being more ageworthy than most of their peers. Grosset's grapes are all hand picked, barrel fermented in French barriques and left to mature in same oak for nearly twelve months, followed by a further twelve months in bottle before release. A mere 590 cases were produced.
