Aside from being absolutely everywhere right now, cold brew coffee is a method of producing rich, delicious coffee over time. Rather than brewing coffee with boiling water, the cold brew method allows you to gradually filter coffee through without burning or diluting the beans. Essentially, the process involves brewing coffee with room temperature or cold water over a 12-24 hour period. Because of the colder base water, you end up with a far smoother and less acidic final result. If you are wondering how to make cold brew coffee, we caught up with the Ben Irvine, trade marketing manager for Manly Vale-based roastery Seven Miles.
