Do yourself a favor and make your own cold brew coffee at home. It's a fraction of the cost, just as delicious, and no fancy equipment required! All you need is a mason jar to make this smooth, refreshing, easy-to-drink iced coffee.
Grind and steep: Use a coffee/spice grinder or blender to grind beans until coarse (see note 1). Transfer ground beans to a mason jar. Add water. Stir thoroughly to wet coffee beans. Cover and put the jar in the fridge for about 16 hours.
Strain: Pour mixture through sieve lined with a paper coffee filter or nut milk bag to strain. Refrigerate, in the sealed jar, until ready to use. Add ice and milk of choice, if desired.
Notes
Grinding beans: Alternatively, you could use coffee grinder at the grocery store (or wherever you buy beans). Select the French press setting.
The cold brew coffee should taste a bit more on the strong side, to account for dilution from added ice and/or added milk. If too strong for your taste, add slightly more cold or room temperature water. If you want a stronger coffee, you can add the beans back and brew for longer, then repeat instructions to strain when ready.
