Brew Strong: Prepare your coffee at double the normal strength. If using espresso, pull 2 shots.
Cool Slightly: If brewing hot, let the coffee sit for 5 minutes. Do not pour boiling liquid directly onto your ice.
Sweeten: Stir in your simple syrup while the coffee is still warm so it dissolves perfectly.
Prepare the Glass: Fill a tall glass to the brim with fresh ice.
Combine: Pour the coffee concentrate over the ice.
Layer: Slowly pour your milk or cream down the inside edge of the glass to create the gradient effect.
Serve: Add a straw, stir gently before drinking, and enjoy!
