How To Make Cold-Brew Coffee

Hot days are here, and the need of a refreshing drink too!

Here is a recipe for a great Cold-Brew coffee, a must try for coffee lovers!


I combine room-temperature water (usually filtered, as my tap water doesn’t taste great) and freshly ground « Costa Rica » coffee in a large French press. The press makes it’s a snap to separate the concentrate from the grinds after brewing.



After about 10 minutes, a solid raft of coffee grinds will form on the surface. I find it important to stir this raft into the water to maximize contact with the ground coffee.



This is the one and only time I stir the cold-brew. As I mentioned before, agitation is last on the list of factors affecting extraction. I find it a nuisance to stir a batch of cold-brew multiple times over the course of a day; the good news is I don’t have to.



Next, I cover the French press with plastic wrap and let it sit at room temperature for 24 hours (give or take an hour in either direction). I’ve done room-temperature brews as short as 12 hours and as long as 72 hours. Twenty-four hours is consistently the sweet spot.



After 24 hours, I remove the plastic wrap and press the grinds to separate the concentrate.



Then I pour the concentrate into a coffee filter-lined fine-mesh strainer set over a large measuring cup or pitcher. Some would say that this filtering step is optional, but I don’t like silt and grit in my cup. Most of the concentrate will filter through unaided, but I find it helpful to gently clear the sediment with a rubber spatula to let the last few drops through.



Finally, I dilute the concentrate one-to-one with a bit of cold water and pour it into a glass with plenty of ice.



Now, instead of reaching for the sugar (which is unnecessary with super-smooth cold-brew) I stir in a pinch of Kosher salt. Just trust me on this one.
