The wine growing regions surrounding the city of Melbourne and Port Phillip Bay are known as the “dress circle”. These include the Mornington Peninsula, the Macedon Ranges and the Geelong region. The overall climate in this part of southern Victoria is temperate, with a moderate rainfall, mainly in the winter and spring. The critical ripening period for wine grapes is in the late summer and autumn, which is the most stable season with, in general, cool nights and dry, sunny days.
