An observation from Italian Winegrape Varieties in Australia (McKay, Crittendon, Dry & Hardie, 1999, Winetitles, p79):
"The climate of Tuscany is most broadly similar to selected locations on the western approaches of the Great Dividing Range in Victoria (e.g., Beechworth), NSW (the Canberra region, Young) and Queensland (Stanthorpe). These regions have in common with Chianti similar heat summations, moderately high sunshine hours, a similar degree of continentality and mean temperatures of the ripening month between 19 and 20.5 [degrees] C"
And yet so much of our experience with sangiovese in Australia is in South Australia, the King Valley and regions such as Mudgee. More to learn yet, I suspect.
