How To Make Iced Coffee at Home

Learning how to make perfect iced coffee is one of the best gifts you’ll ever give yourself. Iced coffee is refreshing in warm weather, and it has a smoother, less acidic flavor than hot java.

With just as much possible variety as hot brews, iced coffee can be enjoyed black or dressed up for a sweet dessert. 

Although it’s been around for a while, iced coffee has experienced an uptick in popularity in the last few decades. According to some reports, the iced beverage made its first appearance in Japan in the 1600s and was known as “Kyoto.” Commentators believe it was a natural progression from the popular iced tea of the time. 

Whether you choose to turn that hot cup of joe into an iced delight or go straight to the heart of the matter with cold brew, you’ll be able to create these fantastic drinks in your own kitchen.

Why Iced Coffee?

Well, the obvious answer must be because it’s wonderful, right? That’s a given, though, as people aren’t going to drink something which tastes horrible.

The iced version is less acidic than the hot version, and this has a few different impacts. Flavors come through more cleanly with the absence of acid, so you can enjoy the taste of coffee as it truly is. Another happy side effect is that for people who may have digestive issues related to hot coffee, iced coffee is often much more tolerable.

While hot java is great on any cold winter day, it may not provide that same comfort when it’s hot outside. Iced coffee is refreshing on a warm summer day, plus you don’t have to wait for it to cool off before taking a sip. You can even turn homemade iced coffee into a dessert of sorts by freezing it or adding whipped cream.

The Story of Iced Coffee

So whose idea was it to put ice in a cup of joe? There’s no way to definitely pinpoint the very first instance of iced coffee, but we do know that one style appeared out of necessity in the 1840s. 

During the Battle of Mazagram, French soldiers in Algeria reportedly had no milk for their coffee and opted to use water instead. They also decided to drink it cold, since the weather was so hot. When they returned to France, they suggested that cafes serve the drink they’d dubbed cafe Mazagram.

Other countries adopted the beverage but made it their own by changing the recipe slightly. Iced java’s popularity within the US didn’t take off until Starbucks introduced its frappuccino in the 1990s. A blended, ice coffee beverage, the frappuccino introduced Americans to the idea that an iced cup of joe could be just as good as the hot stuff.

How To Make Cold Brew Coffee at Home

Cold brew coffee actually originated with the process of brewing cold tea in Japan. Its roots can be traced back to the 1600s, although it took quite some time for this drink to gain popularity in the US.

Cold brew doesn’t just mean iced or cold java; this type of joe is steeped for hours to develop smooth flavors. The longer it steeps, the stronger and more developed its flavor profile. Cold brew coffee has a smoother and less acidic taste than the hot brew version, plus it can also be stored for up to 14 days inside your fridge.

Many people mistakenly believe this brewing process is complicated, but it’s remarkably simple.


Step 1: A coarse grind is best for cold brew coffee. Be sure you grind those beans right before it’s time to brew, as freshly ground beans are always best.

Step 2: Choose your container for brewing, if you’re not using a cold brew coffee maker.

Step 3: A 1:8 ground coffee to water ratio is recommended, so go ahead and measure out your ground coffee and water. You can use either cold or room-temperature water.


Step 4: If you’re using a machine to make cold brew, follow the instructions for your device. If not, move on to the next step.

Step 5: Place the measured coffee in the bottom of your chosen container. Some people choose to use a filter sack for grounds, so you don’t have to filter the liquid later.

Step 6: Slowly pour the measured water over the grounds and stir gently.

Step 7: Cover your container with its lid, then set it inside the refrigerator for 12 to 18 hours.

Step 8: Once the time is up, your java is ready. If you used a filter pack, it’s ready to drink. If not, you’ll need to filter out all grounds before drinking.

Takeya Cold Brew Coffee Maker

The Takeya Cold Brew Coffee Maker is a shatterproof all-in-one machine and can brew one quart of java. This device brews concentrated coffee that can then be diluted for hot or cold beverages. Once brewed, the beverage may be refrigerated for up to two weeks.

Toddy Cold Brew System

It’s easy to use too, just add the ground coffee and then slowly pour water into the coffee maker.

How to Make Iced Coffee from Hot Coffee

Obviously, you can always put ice in hot java and create iced coffee. However, this method takes a little while for the liquid to cool, but the temperature of your beverage may not be even. One sip may be warm, another icy cold. Also, adding ice without altering your coffee to water ratio may result in weak java that just doesn’t taste great.

For those reasons, we recommend flash brewing with a pour-over brewer, a method used to create the Japanese iced coffee we described earlier. With flash brewing, you’re brewing directly onto ice, but you can capture all the flavors that come out with the hot liquid. Because your carafe is filled with ice, the beverage cools very quickly, before flavors become stale.


Step 1: Grind your beans. Light roasts are good for flash brewing, and a medium grind is preferred. The ratio of coffee to water should be 1:10, so you’ll need about 1 ounce of ground coffee for 10 ounces of water.

Step 2: Heat water to boiling or just shy of boiling. Remember that ice will actually replace a third to a half of the total water amount, so you won’t need as much as you do when making traditional hot coffee.

Brewing Process

Step 1: Put five to six ounces of ice in the carafe.

Step 2: Place the filter cone atop the carafe and add ground coffee to the filter.

Step 3: Slowly pour just enough hot water to get the coffee grounds wet and let it sit for about 30 seconds.

Step 4: Continue slowly pouring hot water in a circular motion. The entire process will take two to three minutes.

Step 5: Once all liquid has stopped dripping through the filter, remove the filter, and your beverage is ready!

Iced Coffee Dos and Don’ts

The best way to make iced coffee is ultimately subjective because everyone’s tastes vary. But no matter which method you prefer, there are a few tips and tricks to help you create cracking icy joe each and every time. Here are our iced coffee dos and don’ts.


  • Do use freshly ground beans. If you grind them right before brewing, they’ll have the most flavor.
  • Don’t use pre-ground coffee. Okay, sometimes there might not be any choice, but if you have freshly ground beans, those are always a better choice!
  • Do choose medium or dark roast beans if you’re going for a richer flavor. Lighter roasts will produce flavors that aren’t as potent.
  • Don’t store beans improperly. They should always be stored in a container that is airtight and in a dark location to prevent the flavor from escaping.
  • Do use filtered water for the best tasting drink. Any contaminants that might be in tap water can affect how the beverage tastes.
  • Don’t just put hot coffee in your fridge and then drink it cold. Well, you can, but it won’t be nearly as delicious as it is when brewed properly.
  • Do use coffee cubes to avoid diluting the flavor of your brewed beverage. Simply freeze some of the brewed beverage and use those rather than regular ice cubes.
  • Don’t use regular sugar in iced coffee, as it won’t dissolve well. If you need to sweeten your java, simple sugar syrup dissolves easily but tastes the same.


Knowing how to make cold coffee at home means you can skip the line at your local cafe. You won’t even have to leave the comfort of your own home to enjoy an iced beverage.

Whether you’re making cold brew coffee, chilling the hot version, or flash brewing, you’ll love having the ability to create these delicious treats. Don’t mistake iced coffee for just adding ice to java; iced coffee that tastes great relies on specific steps and methods of brewing.
