We got a great response from you about our article on caffeine in Oolong Tea.

So we started thinking...how can we make that information easier to use?

Besides in-depth info on caffeine in tea, maybe you just want a quick lookup for how much caffeine you are drinking right now! 

And can you guess what?

We just released the Eco-Cha Tea Caffeine Calculator!

Before we go into the features of the Caffeine Calculator and how it works, we just want to tell you that not all of the features have been released yet.

For the first release, we focused on 7 types of Taiwanese Tea.

So let’s dive into the new Tea Caffeine Calculator.

Tea Selection Menu

The calculator is broken down into 3 main sections: tea type, size of tea serving, and amount of caffeine in tea.

The first section is a drop down menu that lets you select the type of tea you want caffeine info for.

You can chose to see how much caffeine is in green tea, high mountain oolong tea, black tea, oriental beauty, wenshan boazhong, dong ding tea, and cold brew oolong tea.

We started with this group of teas, because Taiwan's Tea Research and Extension Station has very good data on their caffeine content. 

 

Tea Serving Size Slider

The second part of the calculator is the tea serving size slider, in ounces.

This section allows you to select from an 8, 12, 16, or 20 ounce serving. After all...how much caffeine is in a cup of tea, depends on the size of the cup. 

Once you have selected the type of tea, and used the slider to select your serving size...voila…

 

Tea Caffeine Amount

Based on your selection of tea and serving size, we’ll show you the amount of caffeine in your tea. That’s it!

The data is pulled from TRES (Taiwan’s Tea Research and Extension Station). Their published data is in Chinese, but remember we’ve translated it to English here.

By using their data, we’re able to give you the precise milligram (mg) count of how much caffeine is in your tea. 

The teas in the calculator range from 26mg of caffeine per cup to 254mg of caffeine per cup and are based on ratios of 1:50 (grams/ml) of boiling water to tea leaves, steeped for 6 minutes. Cold brew was steeped for 4 hours. 

 

Caffeine Visual Slider

Below the caffeine calculation section, we’ve added a colored slider to for a visual representation of the caffeine in each selection.

This provides the same information as above, but in quick visual readout—light green for minimal caffeine (cold brew oolong, smaller servings), all the way to red for a large amount of caffeine (oriental beauty, large cups of black tea).

We added this section to display the amount of caffeine in context, from lowest on the list to the highest.

 

 

This is our favorite part of the caffeine calculator because you can easily see the amount of caffeine on a sliding scale from low to high.

 

Notes on Brewing

The caffeine values found in this calculator are based on a ratio of 3 grams of tea, steeped in boiling water for 6 minutes.

If you steep more or less tea, steep for a different amount of time, or with different temperature water, your caffeine mileage will vary. 

Furthermore, growing conditions, processing methods, and precise cultivar will all affect the amount of caffeine in your final cup of tea.

 

So, what’s next?

We know this is a small selection of the types of teas out there in the world, and you are probably curious about the caffeine in many of them.

We are already working on the next version, with more tea a more fun features! We wish we were able to release everything at once, but this development is a bit tricky, and of course we’ve got tea to source!

One of the features we want to release over the next little while will include the ability to select steep number, as caffeine in tea will vary from the first steep to the last. 

Once we release the steep number feature, we’ll be focusing on adding more and more tea to the calculator.

 

Conclusion

What do you think about the new Tea Caffeine Calculator?

If you haven’t used it, go check it out.

Like we mentioned earlier, this is a work in progress and other features are already being worked on for a future release.

A lot of these ideas come from you guys so, please, the more feedback the better.
