How to make an iced latte
Measure and grind the beans.
Cold brew coffee requires more coffee than traditional hot brew. You need 1 cup (85 g) of ground beans for this cold brew batch, so measure 1 heaping cup of whole beans.
Transfer the beans to the grinder and pulse them until they are about the size of coarse sea salt. The type of coffee you're brewing determines the grind you need, and cold brew uses a medium-coarse to coarse grind.
