Set up your coffee brewer. If you have the OXO cold brew maker, set the filter in the base of the brewing container, then screw on the filter cap. Turn the container around and add in your ground coffee.
Slowly pour water over the coffee grounds in a circular motion, distributing the water as evenly as possible. With the OXO cold brew maker, there is a "rainmaker" cap that helps you with this process.
Once the coffee has finished blooming, give it a quick and gentle stir. Blooming is when the coffee expands and bubbles, releasing carbon dioxide. It can take up to 10 minutes if you use the full recipe.
Set the coffee aside and let it brew for 16-24 hours. We always aim for 18 hours and leave it to brew in the refrigerator.
Once brewing is finished, drain the water and filter out the coffee. (This is the part that is tricky if you don't have a cold brew coffee maker.)With the OXO cold brew coffee maker, you simply set it on the stand and flip the switch. It should take approximately 15-20 minutes with the correct grind size. If you use a French press, use the plunger and carefully pour out the water. Try your best not to agitate the coffee grounds. You may also want to filter it through a paper filter. To do so, pour the coffee out of the French press. Then, set up a pour over coffee maker and pour the cold brew concentrate through the paper. Don't do it in one step because if you have to keep tipping and uprighting the French press as the concentrate filters through the paper filter, you will agitate the coffee grounds too much.
Store the concentrate in the refrigerator.
To serve the coffee, dilute 2 ounces (60 milliliters) (1/4 cup) of coffee concentrate to 4-6 ounces (120-180 milliliters) (1/2 - 3/4 cup) water or milk. You can use serve it either hot or cold. Enjoy!
10 ounces / 284 grams of coffee is roughly equal to 3.5 cups, but your coffee will be 1000% better if you weigh it to make sure you have an accurate measurement.
