I've talked to a lot of people who are confused by iced coffee and cold-press coffee. Many people think there is no difference, but there is.
Iced coffee (like McDonald's is becoming known for) is hot coffee with ice. Really. That's it. Sometimes people add flavor or cream. The coffee is made by running hot water through grounds just like people often make it at home or work. It is quick.
Can you get cold-press coffee hot? Actually, yes! Cold-press is the brewing method. When you make cold-press coffee, you pour coffee grounds and water into a container and let it sit for 8-12 hours. Then you drain the liquid and dilute it 1 t0 4 with water (hot or cold). That is how you make cold-press coffee. Cold-press is less acidic and contains less caffeine than hot-brewed coffee.
Here's the recipe I use for cold-press:
1/2 lb (about 2.5 cups) course ground coffee
4 1/2 cups water
Do not stir. Let sit 8-12 hours. You can use any container. No need for anything fancy.
Strain out the liquid (this can be tricky, but any coffee strainer or mesh strainer will do). Dilute 1 to 3 or 4 with water (hot or cold). I keep the concentrate in my fridge and measure out what I need every morning. It takes up less space in the fridge and gives me the option of having it hot or cold. Enjoy!
