Simple Guide to Making Iced Tea in a Coffee Maker

Quick answer

• Use your coffee maker’s brew cycle to steep tea bags or loose leaf tea directly over ice.
• Aim for a stronger brew than you’d normally drink hot.
• Use filtered water for the best taste.
• Adjust tea amount based on your preference for strength.
• Don’t over-steep; it can make tea bitter.
• Always clean your coffee maker afterward.

Who this is for

• Anyone who loves iced tea but wants a quick, hands-off method.
• Coffee lovers who already have a coffee maker and want to diversify its use.
• People looking for a simple way to make a pitcher of iced tea without fuss.

What to check first

Brewer type and filter type

Most drip coffee makers will work. If you use a basket filter, make sure it’s the right size. Paper or reusable filters are fine, but consider a finer mesh if you’re using loose leaf tea to catch more sediment.

Water quality and temperature

Good water makes good tea. If your tap water tastes off, use filtered water. The coffee maker heats the water for you, which is perfect.

Grind size and coffee freshness

Okay, this one’s a bit of a misnomer since we’re talking tea, not coffee. But the principle is the same: fresh ingredients make a better final product. Use good quality tea. For loose leaf, a medium grind is usually best for drip brewers.

Coffee-to-water ratio

This is where we get a little tricky. You’re essentially making a concentrated tea. A good starting point is double the amount of tea you’d normally use for hot tea. For example, if you use one tea bag per 8 oz of hot water, try two bags per 8 oz of water in the reservoir.

Cleanliness/descale status

A dirty coffee maker can leave your tea tasting stale or off. Run a cleaning cycle or descale if it’s been a while. You don’t want old coffee residue messing with your tea flavor.

Step-by-step (brew workflow)

1. Fill the reservoir with cold water. Use filtered water if possible.

• What “good” looks like: The water level is at your desired brew strength, usually marked on the reservoir.
• Common mistake: Using hot water from the tap. This can affect brewing temperature and potentially damage your machine. Always use cold.

2. Place ice in the carafe. Fill the carafe about halfway to two-thirds full with ice.

• What “good” looks like: Enough ice to chill the concentrated tea as it brews.
• Common mistake: Not enough ice. Your tea won’t be cold enough and will dilute too much as it melts.

3. Add your tea to the filter basket. Use tea bags or loose leaf tea.

• What “good” looks like: Tea is spread evenly in the basket. If using loose leaf, ensure it’s not packed too tightly.
• Common mistake: Overcrowding the filter. This can lead to uneven extraction and bitter tea. Give the tea room to expand.

4. Place the filter basket in the coffee maker. Ensure it’s seated correctly.

• What “good” looks like: The basket clicks or sits snugly in place.
• Common mistake: Forgetting to put the basket in. This will make a mess and the machine won’t brew properly.

5. Turn on the coffee maker. Select your normal brew size.

• What “good” looks like: The machine starts heating water and dripping.
• Common mistake: Accidentally starting a “brew pause” or “keep warm” function. Make sure it’s set to brew.

6. Watch the brew. The hot, concentrated tea will drip onto the ice in the carafe.

• What “good” looks like: A steady stream of dark liquid hitting the ice.
• Common mistake: Leaving the carafe lid open if your machine has a brew-pause feature. This can cause overflow.

7. Let it finish brewing. Wait for the machine to cycle through completely.

• What “good” looks like: The dripping stops and the machine is silent.
• Common mistake: Removing the carafe too early. You’ll get weak tea and a mess.

8. Stir the tea. Once brewing is complete, give the carafe a good stir.

• What “good” looks like: The ice has melted, chilling the tea, and the color is uniform.
• Common mistake: Not stirring. You might have pockets of concentrated tea and weak tea.

9. Taste and adjust. Sample your iced tea.

• What “good” looks like: The tea is strong, cold, and to your liking.
• Common mistake: Not tasting. You might find it too weak or too strong and have to start over.

10. Serve. Pour over fresh ice and enjoy.

• What “good” looks like: A refreshing glass of iced tea.
• Common mistake: Serving it warm because you didn’t use enough ice initially. Add more ice if needed.

11. Clean up. Discard the tea leaves/bags and rinse the carafe and filter basket.

• What “good” looks like: Everything is clean and ready for your next brew (coffee or tea).
• Common mistake: Leaving the used tea in the basket. It can get moldy and smell bad.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Using tap water with off-flavors	Stale, metallic, or unpleasant tasting tea	Use filtered or bottled water.
Not enough ice in the carafe	Weak, watery tea; not cold enough	Fill the carafe at least halfway with ice before brewing.
Using too little tea	Weak, pale, and flavorless iced tea	Double the amount of tea bags or loose leaf you’d use for hot tea.
Using too much tea	Overly bitter, astringent, and overpowering tea	Start with double, then adjust down if it’s too intense.
Not stirring after brewing	Unevenly chilled and concentrated tea	Stir the carafe well to distribute the cold and flavor.
Leaving old coffee residue in the machine	Off-flavors, stale taste, potential for mold	Clean or descale your coffee maker regularly.
Brewing with hot water in the reservoir	Can damage the machine, affect brew temperature	Always use cold, fresh water in the reservoir.
Over-steeping (if machine drips too slowly)	Bitter, astringent, and unpleasant tea	Use good quality tea and don’t let it sit in hot water too long.
Using paper filters for very fine tea	Cloudy tea with sediment	Use a finer mesh filter or a reusable metal filter.
Not cleaning the carafe and basket promptly	Stains, odors, and potential for mold growth	Rinse immediately after use and wash thoroughly as needed.

Decision rules (simple if/then)

• If your tap water tastes bad, then use filtered water because it directly impacts tea flavor.
• If you want stronger tea, then use more tea bags or loose leaf because that’s the primary way to increase flavor intensity.
• If your tea tastes weak, then check your tea-to-water ratio and make sure you used enough tea for the amount of water.
• If your tea tastes bitter, then reduce the amount of tea or check if your machine is brewing too slowly and over-extracting.
• If your iced tea is not cold enough, then add more ice to the carafe before brewing or serve over extra ice.
• If your coffee maker is due for a cleaning, then descale or run a cleaning cycle before making tea to avoid off-flavors.
• If you’re using loose leaf tea, then ensure your filter basket can handle it without letting too much sediment through.
• If you prefer a smoother flavor, then consider using black tea varieties like Assam or Ceylon.
• If you want a lighter, fruitier flavor, then try herbal teas or green teas, but be mindful of brewing times for green tea.
• If you notice a film on top of your tea, then it might be from certain types of tea or hard water; try filtered water.
• If you’re in a hurry, then make sure you have enough ice ready to go so the tea chills quickly.

FAQ

Can I really use any coffee maker?

Generally, yes. Standard drip coffee makers are best suited for this. Machines with complex brewing cycles or built-in grinders might not be ideal. Always check your brewer’s manual if unsure.

What kind of tea works best?

Black teas are classic for iced tea and hold up well to the brewing process. Green teas and herbal teas can also work, but you might need to adjust steep times or water temperature if your machine allows for it.

How much tea should I use?

A good starting point is to double the amount of tea you’d normally use for the same volume of hot tea. For example, if you use 2 tea bags for a mug of hot tea, use 4 for the same amount of water in your coffee maker’s reservoir.

Will my coffee maker taste like tea afterward?

If you clean it thoroughly after brewing tea, no. A quick rinse of the carafe and filter basket is usually enough. For deeper cleaning, run a cycle with water and a bit of vinegar or a coffee maker cleaner.

Is it better to brew hot and then chill, or brew directly over ice?

Brewing directly over ice, as described here, creates a concentrated tea that chills rapidly as it brews. This method avoids diluting the tea too much with melted ice compared to brewing hot tea and then pouring it over a full pitcher of ice.

What if my tea comes out cloudy?

This can happen with some teas, especially if they’re brewed too hot or if you’re using a very fine loose leaf tea with a filter that’s too coarse. Using filtered water and ensuring you don’t over-steep can help.

Can I add sugar or flavorings during the brew?

It’s generally not recommended to add sugar or flavorings directly to the coffee maker’s reservoir or filter basket. These can clog the machine or leave residue. It’s best to add them to the carafe after brewing.

How long does this iced tea last?

Iced tea made this way should be stored in the refrigerator and consumed within 3-4 days for the best flavor and safety. Always use clean containers.
