December 24, 2020

For the TLDR crew get right to looking up how much caffeine is in the tea you're drinking right now with...

The Caffeine Calculator

What's New in The Caffeine Calculator 4.0

[Another TLDR: Added Yerba Mate, White Tea, and LOTS of Bottled Iced Teas.]

Got it...just let me see the calculator!


When we first released the caffeine calculator, we promised you we would update it as much as possible. Our goal is to make this most useful caffeine in tea tool there is! 

We've been listening to your feedback, and we've got the next round of new teas ready to go! 

It is important to know how much caffeine you are consuming, but with so many different teas, sizes, and brands; it can be tricky to figure out exactly how each tea stacks up. 

Ready-to-drink bottled teas have caffeine values listed on the bottle, but how does the caffeine in ready-to-drink tea measure up with loose-leaf tea, or a tea bag? What about steep time? Is double the amount of tea double the caffeine? 

The Caffeine Calculator makes all this easy. 

So, let's get into what's new...


New Loose-Leaf Tea Caffeine Info

Yerba Mate

The traditional South American drink is made from the dried leaves of the Yerba Mate plant. Many people love yerba mate for its health benefits and relaxing properties. And, yes like Camilla Sinensis, Yerba mate does contain caffeineapproximately 60mg per 12 ounce cup, or about as much as a Starbucks Matcha Green Tea Late. Yerba Mate contains less caffeine than an oolong, green, or black tea.

Check out all sizes and compare with all other teas on the list here...

White Tea

Made from young and mostly unprocessed leaves of the Camilla Sinensis plant white tea is not rolled or oxidized and has flavor characteristics that are lighter than green, oolong, and black teas. White tea is primarily made in China, but is also found from Taiwan, Thailand, Nepal, India, Sri Lanka, and a few other tea growing regions. 

A 12 ounce serving of white tea contains approximately 40 mg of caffeine, which is less than green, oolong, black, yerba mate, and most other widely available caffeinated teas.

Bottled Iced Teas, Ready-To-Drink Iced Tea

This is the major part of the update. 

We aim to make this the most complete caffeine in tea reference out there, and that means each and every tea in the world will be included eventually. The first version included loose-leaf teas, then we followed up with popular Starbucks teas. We then added a an advanced version of the caffeine calculator that allowed you to check caffeine by steep number. 

We know that bottled iced tea is one of the most widely consumed beverages in the world, so we figured it was time to include a few of the most popular. 

You can find caffeine info for these drinks on their labels, and on their websitesbut they don't all come in the same size, so it's impossible to compare "caffeine apples to apples"so we've gone a step further and "translated" all of their caffeine values into 8, 12, 16, and 20 ounce servings. So now you can compare directly with all the other teas on the list. 

The Caffeine Calculator 4.0 now included caffeine info on...

Arizona Iced Tea

Snapple Iced Tea

Nestea Lemon Tea

Lipton Brisk Lemon tea

Honest Tea

Gold Peak Tea

...and more!

Competition Grade Wuyi Oolong Tasting Notes | Eco-Cha Tea Club

January 10, 2021

Wuyi was once the specialty tea cultivar of choice in the historical Songboling tea growing region in southern Nantou County. But it got replace with more prolific cultivars in recent decades. We are grateful to have a chance to experience this tea strain that really does stand on its own in comparison to the more popular strains. It has a robust character when made as a lightly oxidized, unroasted tea. And its hardy nature is able to withstand extensive roasting that other strains cannot.

Batch 62 of the Eco-Cha Tea Club comes from the same plot of tea as last month's batch. When we tasted this month's batch of unroasted Wuyi Oolong, following the heavily roasted batch that we shared last month, we were inspired to offer these two very different tasting teas back-to-back. Tasting these two batches of tea that were made from basically the same raw produce (different seasonal harvests), but processed differently, provides an educational experience on how significant processing methods are in determining the final product.

Hong Oolong Tea

Our Hong Oolong Tea comes from Meishan Township, Chiayi County, Taiwan. Meishan is the northeastern corner of the Alishan tea producing region, and in our perception, it generally offers the best Alishan Tea. So, even though Hong Oolong is not commonly made in this region, Eco-Cha (at long last!) has chosen this source for specific reasons.
