Pour-Over Coffee Process: How to Make Iced Pour-Over Coffee, Ice-to-Coffee Ratio, and Brewing Techniques!

Making iced pour-over coffee is wonderfully simple: hot-brewed coffee is flash-chilled with ice in seconds. Refreshing, vivid, and aromatic, iced pour-over has become a warm-weather favorite. But sharp-eyed drinkers have noticed that every coffee shop does it a little differently -- and the difference is not in the extraction parameters at all. It's in when the ice goes in!

"Ice first, brew on top" is the approach most shops use, but plenty of others brew first and add ice afterward. That has sparked endless debate: does ice-first taste better, or ice-later? So today FrontStreet Coffee puts the two methods head to head to find out what really separates them.

Operational Differences

The ice-first method is easy to picture: it simply adds ice to the standard brewing process. Before brewing, you weigh a proportionate amount of ice into the server, where it sits in constant contact with the dripping coffee, cooling the cup and melting as it goes. Once extraction ends, a shake or a stir evens out the concentration and temperature.

The ice-later method is more involved: brew the coffee first, then pour it over ice into another vessel (or drop ice into the finished coffee), and shake or stir until it chills evenly.

Comparative Experiment

For the test we used Colombia El Diviso Estate Sidra, a double anaerobic natural whose bold flavors make subtle differences easy to detect. Both brews used identical parameters -- only the timing of the ice changed:

Coffee amount: 15g
Grind size: EK43 setting 9, fine-sugar texture, 80% pass-through rate on #20 sieve
Coffee-to-water ratio: 1:10
Ice cubes: 100g
Water temperature: 92°C
Pouring method: Three-stage pour
Dripper: V60

Both pots were brewed at the same time. First, water twice the weight of the grounds for a 30-second bloom. Then a second pour of 70ml of hot water from a raised height in small circles, and once it drained through, the remaining 50ml in the same fashion.

Once the liquid finished draining, off came the dripper and it was time to stir.

After stirring, we took the temperatures and started tasting.

Temperature: the ice-first cup measured around 7°C, the ice-later cup about 10°C. Aroma: the ice-later cup was more fragrant. Taste: at first sip, the ice-first group showed more pronounced flavors, while the ice-later pour-over tasted richer.

FrontStreet Coffee attributes the difference to how far the ice had melted. In the ice-first cup, the cubes melted continuously throughout the brew, diluting the coffee as it extracted -- so the concentration starts lower. In the ice-later cup, ice and coffee spent less time together, and the slightly cooled liquid melted the ice less, so the cup kept more of its concentration at first. But give it a few minutes and the later ice melts too -- the two cups end up nearly identical. Without a side-by-side comparison, most drinkers would never notice the difference.

So the real difference lives only in the first few minutes. If you're making a smaller cup, or your ice is soft and "thin," the ice-later method is the safer choice. But if, like FrontStreet Coffee, you prefer convenience and fewer dishes to wash, you can't beat ice-first.

FrontStreet Coffee Recommendation

Iced pour-over deserves beans whose aromatics survive the chill. The FrontStreet Ethiopia Huakui is a favorite for the job: a natural Sidamo with explosive tropical fruit -- strawberry, passionfruit, jackfruit, even lychee -- and almost no bitterness, so the iced cup stays juicy and sweet rather than thin.

The FrontStreet Guodingding Cooperative, a washed Yirgacheffe with citrus, berry, and jasmine notes and a green-tea finish, makes a cleaner, crisper iced cup. And the FrontStreet Strawberry Candy -- a Panama Geisha and Costa Rica honey-process blend -- was practically built for cold drinks: delicate florals plus grape and blueberry sweetness that shine over ice, whether you brew it ice-first or ice-later.
