Petaluma favours cooler climate growing locations; the Adelaide Hills and Coonawarra are maritime and the Clare Valley is moderate continental.

Specialising in unique vineyard sites, Petaluma's Coonawarra Cabernet Sauvignon , Clare Valley Riesling and Adelaide Hills Sparkling Croser are considered quality regional benchmarks.

The original philosophy prevails to this day; to make the best wine, you must plant the right grape varieties in the right region. This has helped to cement the Petaluma wine range as one of the most highly regarded in Australia.
