Cold brew tea has become an increasingly popular way to enjoy a refreshing, chilled beverage, especially during the summer heat. Unlike traditional hot brewed tea, you steep cold brew tea in water at low temperature over an extended period, resulting in a smooth, light flavor with less bitterness.

If you’ve ever wondered how to make cold brew tea at home, this guide will walk you through the simple steps to create a delicious, refreshing drink perfect for cooling down on hot days.

What is Cold Brew Tea?

Cold brew means you brew tea by steeping tea leaves in cold water instead of hot water. This slow extraction process, which you typically do in the refrigerator, allows the tea to develop a mellow, smooth taste without the astringency and bitterness. Cold brewing produces iced teas that taste less bitter, feel more refreshing, and work perfectly as a cool beverage.

Because cold brew uses cool water and a longer steeping time—usually from 8 to 12 hours or overnight—it creates a lighter and more nuanced flavor profile. You can enjoy the subtle flavors and smoothness of cold tea, which makes it a favorite among tea enthusiasts. This method works great for preparing unsweetened iced tea, a popular and lighter option for those seeking a versatile, refreshing drink.

How to Make Your Cold Brew Tea

Making cold brew tea at home is easy and takes no prep time. Follow these simple steps to brew a pitcher of cold iced tea:

  1. Choose Your Tea: Pick your favorite loose leaf tea. Loose leaf tea is best for cold brewing because the leaves have more room to expand and release more flavor and aroma than tea bags. Black tea and green tea are great choices but fruit teas and herbal blends work well too. Choose teas that produce a clear flavor without bitterness.

  1. Measure the Tea: Use about one teaspoon of loose leaf tea per cup of cold water. Adjust to taste. For easy straining later use a fine mesh sieve, infuser or tea ball for loose leaf tea.

  1. Add Water: Fill a pitcher or water bottle with cold or cool water. Don’t use hot or boiling water when making cold brew since we want to extract flavor slowly and gently.

  1. Combine Tea and Water: Put the loose leaf tea in the pitcher or bottle then pour the cold water over it. This makes sure the leaves are fully submerged and ready to steep.

  1. Refrigerate: Cover the pitcher and put it in the fridge. Let it steep for 8-12 hours or overnight to get the best flavor. This slow steeping prevents bitterness and gives a smooth taste.

Best Teas for Cold Brew

When cold brewing choose tea leaves for the best flavor and quality to optimize infusion and straining. Loose leaf tea lets the leaves fully expand and release their flavors and aromas more effectively, resulting in a smoother, more nuanced cold brew with better clarity and depth.

  • Black loose leaf teas: Big flavor that can handle the slow cold steep.

  • Green loose leaf teas: Light, grassy and refreshing flavor that’s especially nice chilled.

  • White loose leaf teas and herbal blends: Like chamomile or hibiscus make great cold brews, delicate and natural flavor without bitterness.

  • Fruit teas: Cold brewing fruit teas from loose leaves brings out their natural sweetness and aroma, often no need for added sweeteners.

Choose fresh, whole tea leaves with large leaves or pieces to ensure maximum flavor extraction during the cold brewing process and make your iced tea experience truly exceptional.

Tips for Cold Brewing Tea

To get the most out of your beverage, keep these tips in mind:

  • This cold brew method works well with all kinds of tea—black, green, white, or herbal—producing a smooth and light brew with minimal bitterness.

  • Whether you use common brands or specialty loose leaf teas, cold brewing offers an easy and effective way to enjoy tea.

  • If you prefer sweet tea, liquid sweeteners such as simple syrup dissolve faster in cold tea than granulated sugar, though sugar will eventually dissolve if stirred well.

  • Experiment with adding sliced lemon, fresh fruit, or herbs to your drink for extra flavor and a refreshing twist. You can also mix different teas or flavors to discover your own version of the best iced tea.

  • Use a pitcher or a water bottle with a tight seal to prevent the tea from absorbing odors in the refrigerator.

  • For the best taste, steep your tea overnight in the fridge, allowing all these variables—tea type, water temperature, steeping time—to come together for optimal flavor.

  • Most importantly, enjoy the process and treat cold brewing as part of your cooking adventures in the kitchen.
