Measure then Grind: Measure and grind approximately 250 milligrams of coffee beans that are freshly roasted.
Prepare then brew: To the filter, add ground coffee, then proceed to slowly pour about one liter of water that is freshly filtered and cold. After 30 seconds, all the grass will bloom. Pour in the quarter-liter of fresh, cold water that remained.
Wait: Leave the coffee to brew for at least 12 hours.
Drain concentrate: Before discarding the grounds, allow the cold brew concentrate to drain completely by first lifting the filter.
Serve and enjoy your drink: Using two parts cold water, dilute one-part cold brew concentrate and enjoy your drink.
