The Buzz About Cold Brew Green Tea

Nothing quite hits the spot like a glass of iced tea when it comes to enjoying a cool, refreshing drink. Most iced tea is made with black tea. To mix things up, try cold-brew green tea. It's not just a tasty beverage; the options are endless on the taste buds! So what makes cold brew green tea so special, how it's made, and why is it perfect for anyone, anywhere?

Alternative to Cold Brewed Coffee

Cold brewed coffee consumption is growing at a double-digit clip so the idea of not having to brew with hot water is becoming more mainstream. Cold brewed tea is lower in caffeine and acidity than coffee and cold brewed green tea is even lower than cold brewed black tea.

How Does Cold Brew Tea Work?

Cold brewing takes a more gradual approach unlike hot brewing, where flavors are rapidly extracted through high temperatures. Tea leaves are left to steep in cold water over several hours, allowing their flavors to infuse slowly and gently. This leisurely extraction process reduces the caffeine content in cold brew green tea compared to its hot-brewed counterpart. Cold brewing also has a knack for reducing the extraction of compounds with inherent bitter taste, resulting in a smoother and more palatable brew. It's all about finding the right balance between patience and precision, ultimately enhancing the tea-drinking experience for any tea enthusiast.

Cold Brew Tea Benefits

Cold brewing is very simple and you don’t have to be concerned as much with water temperature and brewing time. Cold Brew Tea is considered to be more sustainable because of not having to boil hot water which consumes less energy.

Renowned for being rich in antioxidants and plant based nutrients, green tea is famous for enhancing overall well-being and has been proven to do wonders for health. Cold brewing stands out as a method that not only preserves these valuable properties but also provides a refreshing and delightful drinking experience. Green tea is rich in antioxidants such as polyphenols and flavonoids, which contribute to its health-promoting qualities. 

A study in The International Journal of Pharmacognosy and Phytochemical Research found that cold brewing green tea helps keep those important compounds at higher levels compared to brewing it hot. Interestingly, this wasn't the case for black tea. Both cold and hot brewed teas have similar antioxidant activity, so cold brewing is a smart choice for making sure you get the most out of your tea, especially when you don't have hot water on hand.

Cold Brewed Tea Taste

Cold brewed tea offers a tea with lighter body and is smoother drinking compared to hot brewed tea.  Cold brewed tea is also less bitter because of the reduced caffeine. Cold brewing is more forgiving on taste because the extraction method is less aggressive compared to brewing with hot water. 

Is Drinking Cold Brew Tea Good for You?

Yes, if you want tea with less acid and caffeine.  Cold brewed tea contains less acidity and less caffeine. The good news is science shows cold brewed tea can contain the same amount of antioxidants as hot brewed tea.

Cold Brewing Green Tea Guide

Leaf size, ambient temperature and water softness will affect brew time. Sun tea brewed at room temperature or warmer can take 4-5 hours. Therefore, tea brewed in the colder climes or the refrigerator (approx. 36-42 degrees F) takes longer than in direct sunlight. 

Whole leaf tea leaves take longer to brew versus tea bag cut leaves.

Cold brewing with hard water (mineral-rich) will take longer than with softer water.

When considering cold brew green tea, you should start by selecting premium tea leaves or quality tea bags, as they play a crucial role in enhancing the overall flavor and aroma of your brew. Opt for top-notch green tea for better taste and satisfaction. 

Recommended Green Teas for Cold Brewing

Additionally, investing in convenient brewing containers specifically designed for cold brewing can simplify the process and make it hassle-free. A couple of brewing vessels we recommend are the Hario Cold Brew Bottle and the Takeya Iced Tea Pitcher. These containers streamline preparation because they come with strainers, clean up is easy because they both have wide mouths and they both can fit easily in the refrigerator.
