We love this time of year, when the skies turn blue, the sun comes out, and the temperatures rise. But that certainly doesn’t mean your tea-sipping should come to a halt. Did you know that you don’t need hot water to make tea? There’s a method of steeping tea called cold brewing and it’s exactly what you need to beat the heat. Cold brewing involves immersing tea leaves in cold water and letting them slowly infuse overnight in the fridge.
We’re so excited to share this method because it’s a great way to make refreshing, flavorful teas - especially when it’s hot outside! Read below to learn more about cold brewing tea, and see how you can cold brew your own teas all year round.

Why Cold Brew Tea?
Cold Brewed Tea Tastes Amazing
While pouring hot brewed tea over ice to make iced tea instantly does work if you’re making it on short notice, it can sometimes lead to watery, diluted brew that compromises the depth of flavor and overall experience. On the other hand, cold brewing tea is different because it allows the tea leaves to infuse very slowly over time, creating a different balance of compounds than hot steeping does. Cold brewing gives the tea time to develop more complex flavor notes and aromas, all while preventing the release of the bitter tannins and astringent flavors that are normally extracted toward the end of hot steeping. You can cold brew any tea, and the process generally reduces the caffeine content by half of any tea you use. The result is a smooth, easy to drink tea that’s calming and refreshing. Think of how slow-roasting a dish over several hours creates delicious flavors that can’t be achieved by heating in the microwave…It’s kind of like that :)
Cold Brewed Tea Is Safe and Lasts Longer
You may be familiar with sun tea, which is tea that has been brewed outside using heat from the sun. While sun tea is widely considered a summertime tea staple, this method can potentially promote the growth of bacteria when brewed incorrectly. There’s zero risk with cold brewed tea, because you are keeping the tea infusion clean, fresh, and refrigerated. However, cold brew still retains the same amount of healthy antioxidants as hot tea. It also steeps sweeter than hot tea, so you might not feel compelled to add as much sweetener. Additionally, while hot-brewed tea should be consumed the same day it was made, a batch of cold-brewed tea can be enjoyed for several days if it is kept refrigerated! The only factor you should be mindful of is the type of tea you’re cold-brewing; you should give white tea, herbs, and flowers a rinse with hot water first, since they haven’t been processed with heat to kill bacteria. The same should be done with aged puerh as it may have accumulated dust over the years.
Cold Brewed Tea Is Hassle-Free
The only materials required for cold brewing are tea leaves or tea bags, water, and a brewing vessel. All you have to do is combine the tea leaves and water before bed in the brewing vessel to wake up to freshly-brewed and chilled tea! This makes prepping iced tea before events or parties much easier, since you can get all the work done in advance. Plus, it’s very difficult to mess up or over-steep cold brewed tea, so this is a great option for teas that are trickier to brew like delicate greens and oolongs.”
Best Teas to Cold Brew
Cold brewing white tea makes for a smooth, low-caffeine, hydrating tea with sweet, fruity notes. Remember to give it a quick flash brew of hot water to kill any bacteria on the leaves, since white tea is processed without heat. Try cold brewing this delightful white tea: Bai Mudan White Tea by Made of Tea.
We LOVE cold brewing green tea! Cold brewing green tea brings out the fresh, crisp flavor and avoids the bitter element that people often dislike. Try one of our favorites: Wight Tea Co Tropical Green Tea.
Oolong teas are bursting with flavor when they cold brew! For oolongs that are tightly rolled, you don’t need to use as much leaf because of how they expand.
Cold brew black tea makes a classic chilled brew - try different types, such as Nilgiri, Darjeeling, and Assam, to see which flavor profile fits you best! Black tea blends and flavored teas, such as peach, coconut, or mango, can be very refreshing iced as well.
Rooibos and honeybush (herbal tisanes from South Africa) make delicious, soothing, and antioxidant-rich cold brews that go well with many different fruits and flavors. Since they’ve been processed with heat, a flash hot brew isn’t necessary, unless there are herbs in the blend you’re using.
These include yerba mate, guayusa, and yaupon - members of the holly family. Cold brew herbal tea is delicious because the process removes most of the bitterness and mellows out the caffeine levels. Like rooibos, these leaves have been processed with heat, so you don’t need to flash hot brew them. CatSpring Yaupon's Pedernales Green Yaupon is our favorite.
Herbs, flowers, and dried fruits can make a lovely cold brew herbal tea infusion! We love using tulsi (holy basil), mint, ginger, hibiscus, nettles, rose, and lemongrass, to name a few. Be careful with herbs that you’re unfamiliar with and always check with an herbalist or on the package to make sure they don’t need to be boiled in water first. As a general rule of thumb, flash brew your herbal tea with hot water to ensure any bacteria is killed.

What You Need to Cold Brew Tea
How does cold brew tea really work? Honestly, we understand if steeping tea in cold water seems like it wouldn’t actually make tea. You might have to see it with your own eyes to believe it, but we can guarantee that cold brewed tea is a simple, effective, and fun way to make tea!
There are only a few items you need to make cold brew tea: tea, a brewing vessel, a filter/strainer, water, and a fridge. Besides the tea, the container you use to brew it is one of the most important items on the list - you could use a glass jar with a lid, a large pitcher or carafe, a bottle with a lid, or even a plastic container with a lid. The key to the brewing vessel is that you can cover it with a lid, plastic, or foil so your tea steeps in peace! (We don’t want your tea tasting like the leftovers from dinner).
For making a large pitcher of tea, you can buy large single use cold brew tea bags or use several regular tea bags. Or, you can make your own cold brew tea bags with your favorite tea using fillable biodegradable filter tea bags. The large filters are perfect for pitchers of tea while the small filters save you tea and time when making just a cup or two. One of the best reasons to cold brew tea is that it’s easy to experiment with tea flavors. Have a hibiscus herbal and a peach oolong, or a mint green and a lemon ginger? Mix them together, steep them in cold water, and see what happens! It’s hard to go wrong when cold brewing tea.
How to Make Cold Brew Tea
Spring and summer is the time to have fun with cold brewing! Sometimes you’ll find yourself loving a tea when it’s cold brewed, even if you aren’t fond of it hot - or vice versa. You can add fruits, fresh herbs, citrus juice, honey, lime and anything else you like to spice up your cold brewed teas. We also suggest mixing some cold brewed tea into a punch mixture or summertime cocktail for added flavor and health benefits. You can even freeze some of your cold brew batch into ice cubes, and use the tea-cubes in your cup to avoid dilution!
Cold Brewed Tea Recipe
What You'll Need
- Your favorite tea! Not sure what tea to use? Check out our Summer Tea Shop to discover your perfect warm weather tea.
- Brewing vessel: pitcher, cup, water bottle, beverage dispenser, mason jar, iced tea brewer
- Strainer or filter pouch (if you don't have a brewing vessel with a built-in strainer)
- Water (ideally filtered or spring): cool or room temperature
Measure your tea. We recommend adding up to 2x times the amount of tea that you'd use to brew hot tea. Use 1-2 teaspoons of loose leaf tea for every cup of water for a single batch or 4-5 teaspoons of loose leaf tea for every quart for a large pitcher. If you’re using tea bags, less is not more! You want to make sure you wake up to a strong, delicious tea so at least use 3-5 tea bags per quart when making a pitcher of tea. 1-2 tea bags should be enough for a glass or bottle with 1-2 servings. If your brew turns out too strong, you can always adjust the taste by adding more cold water.
Add tea to your container. Put your tea leaves or tea bags in the brewing vessel. You can put the leaves in a filter for easy removal, or put them directly in the water to let them expand.
Add water to the tea and place in the fridge for 2 - 8 hours, or brew it overnight. Generally, the stronger or more astringent the tea (pure green teas, black teas, oolong) you'll want to taste-test at the 2 hour mark. Lighter teas (hibiscus, herbal, white teas) can be steeped longer to extract more flavor. With most teas, recent studies show that the health benefits are optimally extracted at the 1-2 hour mark, so you can start taste-testing then, and enjoy your tea once it's achieved the flavor you like best.
Remove tea from the fridge, strain the leaves or remove the tea bags, and enjoy! Cold brew tea is best served chilled with no ice to enjoy the full depth of flavor.
Tip: Try mixing different flavors of cold brew tea together, sweeten your cold brew tea with a flavored simple syrup, or mix a cold brew tea with lemonade for a refreshing treat!
