Our New Cold Brew Blend from Wazuka

We are frequent visitors to Wazuka, but had only met T on our recent trips. T’s family owns a few tea estates in the surrounding area and welcomed us to sample her products and tour the estate.

The fields dot the hillsides, often requiring a drive up Long windy mountain roads to reach. Because of the steep terrain, many of the tea fields here are extremely small. The smallest is only about a hectare.

T’s family used to produce sencha, as did most of the Wazuka region. However, after matcha grew hugely popular a few years ago, many switched to matcha after learning that the steep hills and rolling fog also makes for good tencha and matcha . T brought us to one of the hillside plots, and shared that the plot produces about 2 tonnes of extraordinarily sweet tencha each year.

We sampled it and were mesmerised. Cold brew matcha is not a common way of enjoying matcha in Japan, but when we tasted it we immediately knew. The matcha produced from that plot has no trace if bitterness at all. It also had a very bright, refreshing sweetness. The umami flavors were less pronounced, but the pleasant natural sweetness made up for it.

We immediately knew that the blend from this plot would prove a hit with our customers. Pouring it over ice and sipping it on a hot day felt indescribably good.

It’s been a few months since, and we are very happy to share our Cold Brew Jade Blend from Wazuka with you. As its name suggests, this blend is best enjoyed mixed with cold water only.

How to make

The best part about cold brew matcha is that it’s so easy to make! You do not need to worry about water temperature, or even whisking technique. Yet it still tastes sublime!

We recommend two main methods. If you don’t have a sealable bottle, then use an electric whisk to stir everything up.

If you have a transparent bottle (glass bottles work great and look awesome!) then simply fill it with matcha and water and shake it up!

Now, remember that matcha is a suspension. This means that if we leave it lying around in a bottle too long, the powder will eventually settle at the bottom. To solve the problem, just give the bottle a good shake before you want to drink it!

How much matcha powder should you use? A 2 gram serving size goes well with 8-12 oz (250-400 ml) of water, but this is really up to your individual taste. Matcha consumed this way is very forgiving.


Matcha is full of antioxidants, and cold brew matcha does not change this. However, many people who start with matcha tell us that cold brew matcha was what got them really interested.

Most of them told us they were intrigued by the better caffeine boost that matcha claimed to provide. Being extremely easy to make was simply a bonus. Many of them were busy professionals – plugging away for corporate America, helping to build the next amazing tech product or hustling to build and grow their own business. What they had in common was a dependence on coffee for energy and for keeping awake.

Cold brew matcha solved many of the side effects of high levels of coffee consumption. Firstly, the caffeine boost was longer lasting and more gradual. Unlike coffee, there was no crash one hour after drinking it. This is due to an amino acid, L-Theanine, that slows the absorption of caffeine into the bloodstream.

Second, people felt calmer and more focused after having matcha. This is thanks to the L-Theanine, which is a known calming agent. For us personally, matcha cold brew is one hack we rely on to attain levels of deep concentration. An ice cold matcha shot is (in our opinion) the best elixir for  humid summer afternoons.

With that, we hope you enjoy the Cold Brew Jade Blend, and we would be very happy to hear what you think about it!
