Melbourne

Melbourne's water is soft. Low in minerals across the board, with very little bicarbonate. That matters, because low bicarbonate means low buffering, which means the water lets acidity through. For coffee, this is a gift if you're working with light-roasted, high-quality beans.

Melbourne's speciality coffee scene didn't develop in isolation from its water. Soft water allows the bright, complex flavours in single-origin, lightly roasted coffees to express themselves clearly. There's nothing in the mineral profile to dampen the acids that make these coffees interesting. It's one of the reasons Melbourne became a global reference point for third-wave coffee.

The flip side is that very soft water can under-extract, producing thin, sour cups if you're not careful with dose and grind. But for pour-over and filter methods where clarity and brightness are the goal, Melbourne's water is close to ideal. It's a natural fit for the kind of coffee the city is known for.
