How to Make Cold Brew Iced Tea (The Easy Way)
Cold brewing tea in the fridge overnight pulls out all the flavor with none of the bitterness.
Cold brew iced tea is one of the simplest drinks you can make at home, and the results beat any hot-brew-then-chill method. Because you never use heat, the tea steeps slowly in cold water and skips the harsh, bitter compounds that hot water extracts. The process takes about 5 minutes of actual work, the fridge does the rest. All you need is tea, cold water, and a pitcher or cold-brew maker.
What Is Cold Brew Iced Tea?
Cold brew tea uses cold or room-temperature water instead of hot water to extract flavor from tea leaves or bags. The steep time is much longer, typically 6 to 12 hours in the refrigerator, because cold water works more slowly than hot. The result is a noticeably smoother, slightly sweeter-tasting tea with very little bitterness. This method works with virtually any tea type: black, green, white, herbal, or fruit blends. It is not the same as making hot tea and pouring it over ice, which can produce a murky, slightly bitter drink.
What You Need
The bare minimum is a pitcher, cold filtered water, and tea bags or loose-leaf tea with a strainer. A pitcher with a built-in infuser basket, like a dedicated cold brew tea maker, keeps things tidy and makes it easy to pull the tea when steeping is done. You do not need any special equipment to get good results; a mason jar with a fine-mesh strainer works fine. If you use loose-leaf tea, plan on about 1 teaspoon per 8 ounces of water. For tea bags, one standard-size bag per 8 ounces is a good starting point.
Step-by-Step Instructions
Add your tea bags or loose-leaf tea to your pitcher or infuser. Pour cold, filtered water over the tea, room temperature water is fine too. Give it a gentle stir to make sure the tea is fully submerged. Cover the pitcher and put it in the refrigerator. Let it steep for 6 to 12 hours depending on how strong you want it; black tea is usually ready around 8 hours, while green and white teas are often better at 6. Remove the bags or strain out the leaves, then serve over ice.
How Much Tea to Use
A good general ratio is 1 tea bag (or 1 teaspoon of loose-leaf) per 8 ounces of water. If you want a stronger concentrate to dilute with ice or water later, double that ratio. For a standard 2-quart pitcher, that means about 8 regular tea bags. Herbal and fruit teas tend to be milder, so you may want to bump up to 1.5 bags per 8 ounces for those. Taste the tea after 6 hours and judge from there, you can always let it go longer, but you cannot un-steep it.
Steep Times by Tea Type
Black tea is the most forgiving and steeps well in 8 to 12 hours without turning bitter. Green tea is more delicate and benefits from a shorter steep of 6 to 8 hours; going longer can introduce a slightly grassy, overpowering flavor. White tea is similar to green tea, 6 to 8 hours is plenty. Herbal and fruit teas (like hibiscus or chamomile) are hard to over-steep and can go 8 to 12 hours or even overnight without issue. Oolong falls somewhere between green and black and usually does well at 8 hours.
Tips for the Best Results
Start with cold, filtered water, tap water with a strong chlorine taste will affect the final flavor. Always steep in the fridge rather than on the counter to keep things food-safe and to slow extraction to the right pace. Remove the tea promptly when it is done; leaving bags in too long, even in the fridge, can eventually make the tea bitter. Store finished cold brew tea covered in the refrigerator and drink it within 3 to 5 days for the best flavor. If you want sweetener, a simple syrup (equal parts sugar and hot water, dissolved) stirs in much more easily than granulated sugar.
Gear That Makes It Easier
A dedicated cold brew pitcher with a built-in infuser basket keeps the process clean and eliminates the need for a strainer. The Takeya 11175 is a popular option at around $33, it is lightweight at under 1 pound, dishwasher safe, and designed specifically for cold brewing. The Brentwood KT-2150BK is a fully automatic iced tea maker that brews directly over ice, rated 4.5 stars from over 8,400 reviews and priced around $45. The Homecraft HCIT2PLSBK6A is another well-reviewed choice at $33 with a stainless steel finish and a reusable filter basket. Any of these make the process more convenient, though a simple pitcher absolutely gets the job done.
Frequently asked questions
Can you cold brew tea at room temperature instead of in the fridge?
Yes, but the fridge is safer and gives you more control. At room temperature, tea steeps faster, usually 2 to 4 hours, but there is a higher risk of bacterial growth if you leave it out too long. Sticking to the refrigerator and a longer steep is the recommended approach.
Why is my cold brew tea bitter?
The most common cause is leaving the tea in too long, even in cold water. Pull the bags or strain the leaves as soon as the steep time is up. Using very hard water or a particularly tannic tea (like some black teas) can also add astringency. Try filtered water and a slightly shorter steep next time.
Can you use loose-leaf tea for cold brew?
Absolutely. Loose-leaf tea often produces a more complex, layered flavor than bags. Use about 1 teaspoon per 8 ounces of water and make sure to use a fine-mesh strainer or infuser basket when you remove it so no leaf bits end up in your glass.
Do you need to add sugar to cold brew iced tea?
Not at all, cold brew tea is naturally smoother and often tastes slightly sweeter than hot-brewed tea, so many people skip sweetener entirely. If you do want sweetness, a simple syrup dissolves much more easily than granulated sugar in a cold drink.
How long does cold brew iced tea last in the fridge?
Once you remove the tea, the brewed liquid keeps well for 3 to 5 days covered in the refrigerator. After that, the flavor starts to fade and it can develop an off taste. Make a fresh batch every few days for the best results.
