How to Make Cold Brew Coffee at Home? What's the Difference Between Cold Brew and Cold Drip? Sharing Cold Brew Coffee Making Methods!

The Rising Demand for Ice Drip Coffee

As the weather heats up, the ice drip coffee at FrontStreet Coffee has once again been selling out. Talking with customers, we found that many people pick ice drip over other iced coffees not only because its taste and flavor differ from everyday iced drinks, but also partly because they figure they could never make it at home.

Understanding Ice Drip Coffee

Ice drip coffee is a type of cold coffee made through long, slow drip filtration with ice water. It typically requires a dedicated device called an ice drip pot. Because ice water extracts so inefficiently, the pot's flow-limiting valve releases the water drop by drop, stretching out extraction time so the coffee extracts fully.

The Challenge for Home Brewers

For the individual enthusiast, though, an ice drip pot isn't a must-have — both because it isn't all that practical, and because it's not cheap and the operation is fussy. That makes many people hesitate: they'd rather just buy a cup of ice drip coffee than spend money on a pot for home use.

A Simple Alternative Method

But here's the thing — ice drip coffee doesn't actually require a dedicated pot. There's a workaround. The equipment is simple and the process genuinely easy! That's right: it's the method FrontStreet Coffee has shared before and that's popular online — using ice cubes and a regular filter cup to stand in for an ice drip pot.

The Simple Setup Process

The setup is simple. Find a filter cup to hold the coffee grounds, then place ice cubes directly on top of the grounds, and your "home version" ice drip pot is done. As time passes, the ice slowly melts into water and extracts the coffee. As long as the room isn't too hot, the ice melts more slowly than you'd expect, so the coffee still gets a fairly complete extraction and ends up rich in flavor.

Important Considerations

Simple as it is, quite a few things can go wrong. Miss a step and the coffee won't extract fully, and the flavor will fall flat. So as FrontStreet Coffee walks through the process, we'll flag the pitfalls to avoid.

"Home Version" Ice Drip Coffee Method

First, the equipment: a container to catch the coffee liquid, 1-2 filter cups of any kind, and 2 filter papers that fit them. For materials, you only need coffee grounds and ice cubes — exactly what you already use for pour-over coffee. It's that simple.

Bean Selection and Grinding Parameters

For this demonstration, FrontStreet Coffee used Costa Rica's Strawberry Sugar beans, but feel free to pick whatever beans you like. As for parameters, one point deserves special attention: the grind. An ice drip pot's coffee chamber is typically a narrow, tall cylinder — a design that thickens the coffee bed, so the water passes through more grounds and extracts more. Filter cups are the opposite: to make extraction more uniform, they're built narrow at the bottom and wide at the top. The same dose poured into a filter cup forms a much shallower bed than in an ice drip pot's chamber, meaning the same amount of water travels a shorter path and extracts less.

Optimal Grinding Settings

So if you want the grounds to reach the same extraction rate, set your grind one step finer than usual. A finer grind shrinks the gaps between particles, increases the area the water must flow through, and pushes extraction to completion. Parameters: coffee dose 25g; coffee-to-ice ratio 1:10; grind Ek43 setting 8.5, 90% pass-through on a #20 sieve (slightly finer than fine sugar, two steps finer than hot pour-over). With everything ready, you can start making ice drip coffee.

Step-by-Step Brewing Process

First, wet the filter paper, add the grounds, then pour room-temperature water equal to the coffee dose to "bloom" the bed. This bloom isn't for degassing — it's to wet the grounds so the dripping ice water can reach coffee outside the water's direct path through capillary action. Keep your pouring height as low as possible and the water volume minimal here, so you don't punch holes in the bed, which would cause under-extraction.

Managing Initial Extraction

After pouring, some water will drip straight through into the server. Pour that first run-off out — it's too cold to have carried much coffee substance, and keeping it would only dilute what extracts later. Then cut two pieces of filter paper roughly the size of the coffee bed's surface (a round filter paper works if your dose is small), lay them flat on the bed, and wet them. Because ice water drips as discrete droplets, these papers spread the drips evenly across the bed — don't skip this step.

Adding Ice Cubes

With the paper in place, pile the ice cubes on top. The filter cup won't have room for all the ice at once, so just add it in batches.

Using Two Filter Cups Method

If you have two filter cups, you can instead dedicate one to holding the ice (like the setup on the right in the photo below). That way all the ice goes in at once and you don't have to keep checking the melt rate. One caveat: you must line that ice cup with filter paper first, otherwise the melting ice will shrink until pieces slip right through the cup's holes and crash into your carefully smoothed coffee bed.

Completion of Extraction

Finally, just wait for all the ice to melt, remove the filter cup, and the coffee extraction is complete!

Final Fermentation Process

But the coffee isn't finished yet! At this point the ice drip coffee hasn't taken shape — it needs a long spell in the fridge to develop its flavor, wine aroma, and fermentation character. So seal the brew well with plastic wrap or transfer it to a sealed bottle, and refrigerate.

Ready to Enjoy

After 8 hours, the ice drip coffee is officially ready. You can pour it over ice as-is, or extend the refrigerated fermentation to push the wine aroma even further.

FrontStreet Coffee Recommendation

For home ice drip and cold brew, FrontStreet Coffee's Strawberry Candy Geisha blend is a stellar pick: Panama Geisha brings classic rose and orange florals, while Costa Rica honey-processed coffee adds grape, dried blueberry, and strawberry-candy sweetness. The resulting cold brew is sweet-tart, vibrant, and — after a spell of fermentation — takes on an almost fruit-wine character.

If you'd rather keep it economical, FrontStreet Coffee's Washed Gedeb Cooperative Yirgacheffe is a budget-friendly daily bean that handles cold extraction beautifully, showing sweet berries, layered fruit, and honey notes. And for a juice-like iced coffee, the Kenya Cherry Tomato — SL28 and SL34 varieties from Thika, 1550-1750 meters, K72 double-washed — delivers vivid cherry tomato and black plum acidity over ice, low in bitterness and endlessly refreshing.
