If you love iced coffee but hate the watery taste that comes from ice melting into a regular brew, a coffee concentrate is the answer. And one of the easiest ways to make it? Your Instant Pot. This method produces a smooth, rich concentrate that’s perfect for iced coffees, frappuccinos, and even baking — without paying those crazy cafe prices.
What You’ll Need
- 1.5 cups of coffee grounds (regular grind — not coarse, not fine)
- Water to fill the Instant Pot to the max line (roughly 16-18 cups)
- A reusable coffee filter or cheesecloth-lined colander
- A large bowl for straining
You can use any type of coffee — any flavor, regular or decaf. If you use regular, just keep in mind that the longer you steep it, the higher the caffeine content will be.
One tip: filtered water produces a smoother taste compared to tap water.
The Instant Pot Method
- Add your 1.5 cups of grounds to the Instant Pot.
- Fill with water to the max line.
- Lock the lid and make sure the valve is set to seal.
- Set to manual, high pressure, 5 minutes.
- When the timer finishes, use the natural release method — let it depressurize on its own until the lid is safe to open.
- Let the concentrate cool to approximately room temperature. This takes about two hours, but it serves a purpose: the longer it steeps, the stronger the flavor and caffeine content.
Straining the Concentrate
Once the concentrate has cooled, you’ll need to strain out all the grounds. The best approach is to ladle it through a reusable coffee filter set in a cup over a large bowl. If you don’t have a coffee filter, a colander lined with cheesecloth works just as well — the cheesecloth prevents fine grounds from slipping through the larger holes.
Squeeze out the filter when you’re done to capture every last drop of concentrate.
Storing and Serving
Pour the strained concentrate into a jar or pitcher and store it in the fridge. Because you’re using a 1:1 ratio of concentrate to water, this batch will last quite a while. For one serving, mix half a cup of concentrate with half a cup of water (or milk), add ice, and you’ve got a full cup.
You can customize from there — cream, sugar, coffee creamer, whatever you like. But even served black, the concentrate produces a remarkably smooth, almost creamy taste with no wateriness. It’s a rich, full-bodied iced coffee that rivals anything you’d pay a premium for at a coffee shop.
