Wow! I love this tea maker. I've tried all sorts of tea and every brew has been delicious. I have arthritis in my hands and this system makes tea making so easy. Well worth the wait and well done.

Tea was perfectly brewed, and the perfect temperature. The surplus stayed warm quite awhile and I also did the “warm/reboil” with excellent results. I own a cute gooseneck electric water kettle that I love using, but that will now be for coffee. This is uniquely perfect at making tea.

It's a triumph! The wait has been well worth it! Bravo!.

I brew it on strong mode. And added hot milk. I got the special tea powder from Malaysia. So it’s actually a kopitiam teh, that’s what we call milk tea in Malaysia. I live in HK. That’s my taste of home every morning.

1. All set up, cleaned, and connected to the app! 2. Trying this black tea a friend brought me. 3. Perfection! I didn't even add honey. I think my favorite aspect of the design is that it saves me from walking away, getting distracted, and winding up with half hour steeped tea XD

How our patented aero-brew system works

The patented system controls the 4 essential elements for perfect tea brewing: temperature, time, water flow and tea leaf immersion. 


The Qi Aerista story

With over thousands of tea types out there, how can we brew them correctly to get that perfect balance in tea taste?

Rick Ha, a lifelong tea drinker with a PhD in Computer Engineering from University of Waterloo, Canada, set out to find a solution.

Taking inspiration from different methods of tea brewing, Rick envisioned a smart tea maker that can control the 4 key elements of tea brewing: temperature, time, water flow and tea leaf immersion

After 5 years of research, prototyping and product development, Rick and his team invented the patented AERO-BREW system and the Qi Aerista Smart Tea Brewer was born.

Product features

How does Qi Aerista’s brewing mechanism work?

Our patented AERO-BREW system drives water flow through a specially designed mechanism without the use of a traditional water pump. Inside the infuser, there is another in-house designed mechanism that enables immersion of the tea leaves. Combining with heating and countdown control, the AERO-BREW system is able to control the 4 key elements of making great tea, which are temperature, time, flow and immersion.

How does Qi Aerista works?

Just 4 simple steps:

(1) add water to the glass pot;

(2) put tea leaves or tea bag in the infuser;

(3) select the type of tea on the touch panel; and

(4) tap the “Brew” button to brew tea. 

That's it! The smart tea maker will buzz you when the tea is done. Once the tea is ready, it will switch automatically to keep warm mode. Your tea will be kept warm at 70C/158F for 60 minutes.

What color option do you offer for Qi Aerista?

Currently, we offer one color, the Cool Grey. 

What voltage and power plugs does it have and use?

We are offering 3 versions: 

- 100-120V & US/CA plug

- 220-240V & EU plug

- 220-240V & UK/HK/SG plug

Product usage

How does Qi Aerista notify me when the tea is ready?

After brewing is complete, there will be a beeping sound to alert you that your tea is ready. Qi Aerista has a keep warm function to keep your tea warm at 70C/158F for up to an hour. 

It is mentioned that Qi Aerista can essentially brew all types of tea. Exactly what types of tea can Qi Aerista brew?

Not only it can brew traditional teas like green tea, black tea, white tea, pu'er tea, oolong tea, and herbal tea,  this smart tea maker can also make cold brew teas and strong brew teas. Cold brew teas are teas brewed at room temperature (25C/77F). Green teas and finer teas (e.g. CTC, broken pekoe) are great for cold brewing. 

In addition, Qi Aerista can make super strong teas for all our milk tea and Chai tea fans. No more re-heating of your teas after a long steep. Simply add milk to the tea after brewing is complete.

Can Qi Aerista do cold brewing tea?

Yes! The smart tea maker has a designated program for cold brewing. Simply tap on the 'Cold' button and your crisp and refreshing cold brew tea will be ready in 10 minutes as compared to a few hours if brewed manually.

I drink really strong tea and love to add lots milk to my tea. Is Qi Aerista for me?

Absolutely! The smart tea maker has a preset mode 'Strong' to meet your needs. The tea will be brewed for 8 minutes at 95C/203F. 

Can I add milk to the Qi Aerista borosilicate glass pot?

We do not recommend putting any liquid other than water and tea to the pot and it will make the cleaning of the pot difficult.

Can we use Qi Aerista just to boil/heat the water?

Yes! You can use Qi Aerista as a variable temperature kettle via the HEAT function. We provide 8 default heating settings. You can also customize to any temperature between 25C to 100C (77F to 212F) as you like.

I heard that Qi Aerista is the first smart tea maker that can make Hong Kong-style milk tea right at home. How does it work?

Qi Aerista has a preset 'Strong' brewing program that is perfect for Hong Kong-style milk tea. After brewing is complete, simply combine the tea and evaporated milk in a mug. You can check out the full recipe in our blog.

Can we use tea bags or loose leaf tea with Qi Aerista?

Certainly! For small pieces of tea like fannings and dust grade, we strongly suggest placing them in tea filtered bag before brewing them in your Qi Aerista. 

How much tea leaves/water can I add?

We recommend using  one heaped teaspoon (about 3 grams) for every 230ml (about 8oz) of water.

What kind of water should I use?

Avoid choosing water that is high in mineral contents as you may find unwanted metallic flavor in your tea.  Also, if the water’s mineral content is too high it will leave scale deposits in your pot. Absolutely purified water is also not recommended as it will make the tea flat and dull. As a result, we advise using clean drinking water that has either low or balanced mineral content.

Is Qi Aerista easy to clean?

Absolutely, all parts in contact with water (e.g. infuser and pot) can be removed for cleaning or rinsed under the tap.

The quality of our tea is mainly the most important feature. The teas we chose are high grade, authentic Chinese teas and each teas we selected need to meet the following criteria:

(2) Authentic. The taste, aroma, and appearance should match the profile of the tea type.

(3) Safe. The teas must be safe for us to consume and it is our number one consideration. We source from reputable, experienced tea farmers that practice biodynamic or organic farming. Our tea farmers care about their plantation and teas as much as we care about our cup of tea.
