What's Cold Brewing?

Did you know that you don't need hot water to make tea?

There is a method of steeping tea called “cold brewing”, where you put tea leaves in cold water and let them infuse slowly.The taste of the tea is different from regular steeping. Even if you don't like the regular "hot brewed" black tea, you might like it if it is "cold brewed".

Spring and summer are the seasons to have fun with the method! Isn't it nice if you can make delicious iced black tea without boiling water? It's a great way for busy morning or for parties and events, as you can get all the work done in advance. It's easier to make, difficult to mess up.

Let's learn some tips to make a delicious cold brewing black tea !


Taste Difference between Hot and Cold Water Brewing

The taste of cold brewed tea is different to regular hot water steeping, as by infusing slowly in water, the tea is milder and sweeter. It’s easy to drink as that’s soft and calming.  

The taste difference comes from the levels of tannin and caffeine, which gives us astringency and bitterness. They are very low in the cold brewing as tannin and caffeine need a high temperature to be extracted from the tea leaves.So, cold brewing would be good for someone who is caffeine intolerant, or someone who drinks a lot in a day. You can also enjoy it without sugar, as you can feel a gentle sweetness in your mouth.  


The Choice of Black Tea 

Full-bodied type of black tea usually taken with milk such as Assam would not be good for cold brewing. Light and fruity black tea such as Darjeeling would be better.

Either using a tea bag or loose tea leaves is fine. 


The Choice of Wakoucha, Japanese Black Tea 

Japanese black tea ,or wakocha 和紅茶, is produced using tea cultivars meant for Japanese green tea such as Yabukita, Okumidori and Sayamamidori, or using tea cultivars specially developed for Japanese black tea such as Benifuki, Benihikari.



The black tea grown in the Japanese climate tends to be milder and less astringent than black teas from other part of the world. The flavor matches Japanese cuisine and wagashi (和菓子, Japanese confectionaries) very well. Some people say the flavor is special, somewhere between green tea and black tea, although the flavor is different depending on the cultivar and tea producer.

Wakoucha Japanese black tea is a good option for cold brewing.


What You Need 

You need tea, a container with lid, water and a fridge.

Biogradable fillable tea bags would be useful to make tea with loose leaf tea as you can take the leaves out easily.
