The Best Iced Pour Over Coffee Recipe (Flash Brew Method)
Why I Started Experimenting
Most flash brew coffee recipes suggest brewing with less water and replacing the missing amount with ice. A common approach is to pour half of the brewing water at the start, then add the remaining half around the one-minute mark before letting the coffee draw down.
When I tried this, I found the coffee tasted a little lighter than I wanted.
It makes sense when you think about it. With less hot water passing through the coffee bed, there's less opportunity to extract flavour from the coffee. In my testing, this sometimes resulted in an iced filter coffee that tasted a little thinner and occasionally slightly under-extracted.
Of course, everyone's preferences are different, and once the coffee is cold these differences become less obvious. But I wanted to see if I could create a sweeter, fuller cup without changing the coffee-to-water ratio.
A Simple Change That Made a Big Difference
Instead of making two large pours, I started treating the recipe more like a standard pour over.
Using several smaller pours extends the contact time between the water and the coffee while still using the reduced brewing water needed for a flash brew recipe. I also added a gentle Rao Spin after each pour to keep the coffee bed level and encourage an even extraction.
The result is a brew that still finishes in around four minutes but tastes noticeably sweeter, rounder and more balanced over ice.
I've found it brings out more of what makes speciality coffee so enjoyable, even when served ice cold.
My Iced V60 Pour Over Coffee Recipe
Coffee: 15g
Hot Water: 170g
Ice: 85g
Grind: The same grind setting you'd normally use for a hot pour over.
Brew Method
Brew the coffee exactly as you would a normal pour over, but using just 170g of water.
0:00 – Pour to 50g, then give the brewer a gentle Rao Spin.
1:00 – Pour to 80g, followed by another gentle Rao Spin.
1:30 – Pour to 110g, then Rao Spin again.
2:00 – Pour to 140g, followed by another Rao Spin.
2:30 – Finish the pour at 170g, then give the brewer one final gentle Rao Spin.
Allow the coffee to draw down naturally. The total brew time should be around 4 minutes.
The Secret: Cool the Coffee Gradually
This is the part that made the biggest difference during my testing.
Rather than brewing directly onto a full glass of ice, brew the coffee first, then cool it by adding the ice one cube at a time, stirring continuously between each addition.
At first this might seem slower, but it actually chills the coffee much more efficiently.
When you brew directly onto a large amount of ice, a lot of that ice melts immediately because it's absorbing a huge amount of heat all at once. By adding the ice gradually while constantly stirring, you bring the temperature of the coffee down much more quickly, meaning each cube has less heat to absorb and melts more slowly.
The result is an iced pour over that's colder, sweeter and less diluted, allowing more of the coffee's natural character to shine through.
For this recipe, continue adding and stirring until you've used the full 85g of ice, You then have lovely cold but correct strength filter coffee! I like to then pour this cold coffee over yet more ice!!
Best Coffee for Iced Filter Coffee
Lighter roasted speciality coffees tend to shine when brewed as iced coffee. Look for coffees with tasting notes such as:
- Citrus
- Peach
- Berry
- Tropical fruit
- Floral notes
At Freda Coffee, we particularly enjoy naturally processed Ethiopian coffees and vibrant washed Kenyan coffees as iced pour overs during the summer months.
Final Thoughts
Learning how to make iced coffee at home doesn't need to be complicated. Whether you're brewing with a V60, Aeropress, French Press or another filter brewer, simply replacing one-third of your brewing water with ice creates a delicious, balanced iced coffee every time.
It's one of the easiest ways to enjoy speciality coffee during warmer weather while preserving all the sweetness, acidity and clarity that make great coffee so enjoyable.
I've tested quite a few iced coffee recipes over the last few weeks, and this is the one I'll be sticking with this summer. It gives me a sweeter, cleaner and more balanced cup while keeping everything I love about freshly roasted speciality coffee. If you give it a try, let me know how you get on.
