To make Aeropress iced coffee, start by calculating a coffee-to-water ratio 1:16, using a mix of hot water and ice cubes to create a concentrated brew. Place a paper filter in the Aeropress, add coffee grounds, pour hot water, stir for 30 seconds, and then let it brew for 2 minutes before pressing into a decanter filled with ice.
CalculationThe ideal coffee-to-water ratio for Aeropress is 1:16. You should use 16 water units for every 1 unit of coffee grounds. To give an example from this brew, 400 ml (13.5 fl oz) of water should be used for 25 grams of coffee grounds.We will use part of this water as hot water and part as ice cubes. This way, we will make a more concentrated brew to balance the dilution that ice cubes will make in the coffee.Weigh 240 ml (8 fl oz) of the 400 ml (13.5 fl oz) water as hot water and 160 ml (5.5 fl oz) as ice cubes. 1 ml of water equals 1 gram. Therefore, you can go by weight rather than volume because measuring the volume of ice cubes will be quite difficult.
Heat the WaterConsidering the water you’ll use to preheat the Aeopress, heat the water to 200 °F (93.5 °C). If you don’t have a thermometer, boil the water. Then let it rest for 1 to 1.5 minutes. This way, you will achieve an ideal temperature for brewing.
Prepare Your AeropressPlace a paper filter in Aeropress’s filter cap and mount it to the brewing chamber.If you wish, you can rinse the paper filter, but since Aeropress’s paper filter is quite small, even if you don’t rinse, you will not likely taste the paper in your coffee.
BrewPlace the decanter on the scale. Put the ice cubes in the decanter. Then place the Aeropress on the decanter. First, pour the coffee grounds and hot water into the Aeropress.
Stir and WaitStir the mixture gently with the Aeropress’s paddle for 30 seconds. Then place the plunger in the chamber and pull it up slightly. This will stop the water from dripping from the bottom.Wait for 2 minutes to brew.
Press the PlungerPress the Aeropress’s plunger without applying too much force at a steady speed. Keep pushing until you hear a hissing sound. This sound means that the water inside is finished.
ServeThe ice in the decanter will probably have completely melted due to the effect of hot water. Serve with plenty of ice in the glasses. If you wish, you can serve it with milk.
Notes
Adjust Coffee-to-Water Ratio: Experiment with the coffee-to-water ratio to achieve the desired strength. Since the coffee will be poured over ice, a slightly stronger brew is recommended.Flavor Enhancements: Customize your iced coffee by adding flavor enhancements like vanilla extract, simple syrup, or a splash of flavored creamer for a personalized touch.Experiment with Milk Alternatives: If you enjoy creamy iced coffee, try using different milk alternatives like almond, coconut, or oat milk. These can add unique flavors to your beverage.Sweeten Smartly: If you like your iced coffee sweetened, consider using liquid sweeteners like simple syrup. They dissolve easily in cold beverages.Cold Coffee Ice Cubes: Freeze leftover coffee into ice cubes. Use these cubes in your iced coffee to prevent dilution and maintain the coffee's strength.
