These days, cold brew coffee is all the rage. Known for its smooth, rich flavor and extra kick of caffeination, cold brew coffee has rightfully earned its claim as you go-to bev of the summer. But its lesser-known counterpart, cold brew tea, may just beat it out this year -- and we want you to be the first to know all about it when it's the next big thing.

Cold brew tea is tea that has been steeped without the application of heat, changing up the flavor and composition of the beverage. We're confident that the cold brew technique can turn any tea skeptic into a fan, and we'll take you through our favorite ways to enjoy it.



What is Cold Brewing?

Cold brewing has been practiced for centuries now. The practice first originated in Kyoto, Japan. The cold brew tea technique was initially only used to make coffee without using fire or other dangerous heat sources. But in the 1600s, the Japanese discovered that cold brewing was able to produce a smoother and sweeter flavor of tea; when brewing tea using heat, tea leaves can be burnt, eliminating some of their flavor and health benefits. Thus, cold brewing became a well-known and well-loved practice as time passed, even outside of Japan.

Cold brewing essentially works by steeping tea without a heat source. Where heat extracts flavor from a typical brew of tea, time is the ingredient that extracts flavor in the cold brew process.

While it does take a long time to steep, the robust flavor and quality of the resulting cold brew tea makes it well worth the wait.

Why Cold Brewing Makes the Best Tea

Cold brewing is one of the best ways to make tea because the leaves are able to retain their flavor and health benefits. Like the Japanese believed in the 1600s, subjecting the tea leaves to hot brewing methods can strip them of their flavor. Since cold brew only requires you to place the leaves in cool water and store them in the fridge, the original flavor of tea steeps naturally in the water. This results in a rich, smooth flavor that you won’t be able to find in standard tea.



The Difference Between Iced Tea and Cold Brew

While both iced tea and cold brew tea may sound similar, they actually differ in process, quality and flavor.

As mentioned above, cold brew tea is made by leaving tea leaves inside either room temperature or cold water for a prolonged period of time. Iced tea, on the other hand, is brewed in hot water, cooled down, and served with ice later on. This can result in a watered down version of your tea. With cold brewing, you can use the same amount of tea you would typically use for a iced tea without having to worry about it being watered down by ice later on.

Another difference between cold brew tea and iced tea is that cold brew tea will never brew bitter. If you choose to steep your cold brew tea for 24 hours, it will still brew a perfectly smooth cup of tea. Iced tea, on the other hand, still relies on an initial hot brewing method. This runs the risk over over-brewing and churning out a bitter result, which may only taste more bitter when served as iced tea.



The Benefits of Cold Brewing Tea

There are several benefits to making and drinking cold brew tea.

  • Saves time: We know this may be confusing, since we’ve mentioned that cold brewed tea takes hours to make; however, if you look at the bigger picture, the overnight process is more convenient if you’re rushing in the mornings. If you’re running late, hot brewing tea is very inconvenient; you need to wait for water to boil and the tea to steep.

If you cold brew your tea the night before, it’ll be ready and waiting for you in the morning. When using a Mosi tea infuser, you can grab it straight from the fridge and take it on-the-go.

  • Supports cardiovascular health: Did you know that drinking cold brew tea could support your heart? A study by the New York Times reports that those who regularly drink cold brew tea are 21% less likely to have a stroke.
  • Tastes good on its own: Tea is undeniably one of the healthiest drinks. With other forms of brewing, the tea may turn out bitter or dull, which encourages drinkers to add sugar or other sweeteners. Cold brew tea retains its original sweetness, so many tea drinkers are able to enjoy it without any additional flavorings.
  • Contains less caffeine: Teas are a great substitute to coffee in general because most of the time, they contain less caffeine. However, if your body is sensitive to caffeine, then you can lower your caffeine consumption in tea by drinking cold brew tea. This is because the cold brewing process extracts less caffeine from the tea leaves, keeping the caffeine content in cold brew tea at a minimum.
  • Boosts your immune system: Cold brew tea retains more vitamin C than hot brewed tea or iced tea. This is because hot brewing tea strips the tea leaves of their natural nutrition and health benefits. With cold brewing, you’re able to retain its high levels of Vitamin C content. This means that drinking cold brew tea frequently gives you an added boost of Vitamin C to help your immune system work its best.



The Best Types of Tea for Cold Brew

While you can use any tea with the cold brewing method, certain types of tea will especially shine through when brewed cold.

  • Morning Black Tea: Its soft, honey-like flavor is guaranteed to shine through with the cold brew method, letting tea drinkers enjoy its naturally sweet flavor without any additives or sweeteners.
  • Orange Spice Tea: This tea offers a unique and earthy taste, with hints of citrus and spice. Its fruity, floral flavor is guaranteed to stand out once it’s used to make a refreshing glass of cold brew tea.
  • Rose Black Tea: This is one of the most unique but flavorful teas in our selection. It’s a great option for cold brew tea, offering an woody black tea flavor with a strong floral sweetness to match.
  • Everest Oolong: This tea has a unique You will be able to note the undeniable tastes of grape and tannins once it's brewed, which adds to its charm.
  • Green Mint: The bright notes of spearmint, peppermint, and lemongrass are emphasized with an added touch of sweetness when brewed cold.

Loose leaf teas are the best option if you’re looking to make cold brewed tea. You can also use teabags, but they won’t offer the same quality of taste and nutrients as drinking a cup of tea made with loose tea leaves.

This is because loose leaf tea offer the largest surface area of tea leaf for the water to interact with. When you're using tea bags, the tea is often ground up to fit into the tea bag. This results in a lower quality, less flavorful tea as there leaves have a smaller surface area that interacts with the water than a whole, loose leaf tea.

Using loose leaf tea allows the drinker to get the best of its benefits, both in terms of its health advantages and taste. For the best-tasting and most nutritious tea, try making your next cup by cold brewing loose tea! Mosi's loose leaf teas are all hand-picked and incredibly high quality to brew the perfect cold brew cup.
