Method
1
Combine coarsely ground coffee with cold filtered water in a large jar or cold brew maker.
2
Gently bruise rosemary sprigs by rolling with a rolling pin or muddling lightly to release oils.
3
Add bruised rosemary sprigs, orange zest, and lemon zest to the coffee mixture.
4
Stir gently to combine all ingredients evenly.
5
Cover and steep at room temperature for 12-16 hours.
6
Strain mixture through fine-mesh sieve lined with cheesecloth or coffee filter, pressing gently on solids.
7
Strain again through clean filter for clearest result.
8
Serve over ice in tall glasses, garnish with orange slice and fresh rosemary sprig.
9
Store remaining cold brew in refrigerator for up to 5 days.
Barista note: Taste before adjusting — a small change in grind, dose, ratio, or time usually makes the biggest difference.
