Water & Climate

East of Melbourne lie the Yarra Ranges, densely forested hills that supply the city with much of its drinking water. Access is restricted so that no livestock or fertilizer can reach the water before it filters through eucalyptus forest and settles in the reservoirs.

What's notorious, though, is what happens to that water once it reaches the distilleries in and around Port Melbourne. Melbourne is known as a city with four seasons in a single day. A morning can start with drizzle at twelve degrees Celsius. It can end in dry heat above thirty degrees, before cool air rolls back in from the bay by evening.

For a distillery, that swing isn't a nuisance, it's a tool. Every temperature shift makes the barrel's wood work. It expands in the heat and contracts again in the cool. In doing so, it drives the whisky deeper into the wood than a steady climate ever could.

Scotland matures its casks in steady, damp coolness over decades. Kentucky relies on hot, dry summers and cold winters, also with sharp swings. Victoria sits somewhere in between: Mediterranean-warm in summer, mild and damp in winter, with daily weather swings layered on top. The result is a climate that compresses the effect of long aging into a fraction of the time, with consequences for color, aroma, and the share that evaporates as the Angel's Share.

Anyone who thinks a warm climate only breeds impatience is underestimating Melbourne. The same fickle weather that ripens the wine in the valleys around it keeps right on working on the whisky in the barrel afterward.
