Highest Caffeine Teas

11 Highest Caffeine Teas in 2022

Interested in energizing teas with a caffeine kick? Check these out! Our highest-caffeine teas provide not only great flavor, but also a powerful boost of energy. Our recommendation is to go with a tea with up to 80–90 mg of caffeine for the best experience. Here are a few great recommendations for high-caffeine teas, as well as what to look out for!

How Much Is Too Much?

In addition to its profound effects on the brain and nervous system, caffeine is an extremely powerful chemical. Caffeine is the main component of any caffeinated beverage, and, in the right amount, it will keep you awake, alert, and productive.

How does caffeine do this?

Your brain is like a circuit board filled with transistors and delicate circuitry that changes state depending on the current passing through it. Your brain has certain receptors that can fire or relax just as a switch does.

Usually, the firing or “on” state results in stimulation, while the “rest” or “off” state results in relaxation and winding down. In our hypothetical brain circuit, if you zoom in on the area that controls alertness, you will find that the circuits in that area fire and relax under different circumstances.

In the office, several circuits will continuously fire, enabling you to stay focused and alert. However, as you wind down at home, the circuits will gradually cease firing and go into a relaxed state, eventually putting you to sleep.

Here’s where caffeine comes in! After consumption, caffeine enters the brain and binds to certain receptors (or, in our analogy, circuits).

A constant firing of your brain’s circuits causes you to remain awake and alert because it blocks the circuits that control wakefulness, alertness, and focus. Increasing the amount of caffeine you consume or consuming it more frequently increases its potency.

But how much is too much?

According to many health agencies, adults should not consume more than 400 mg of caffeine per day. As a result, you should limit yourself to drinking 3–4 cups of tea (each with 80–90 mg of caffeine) per day. There are several options available for not just a daily caffeine fix, but also great taste!

Buyer’s Guide For Highest Caffeine Teas

Buying a highly caffeinated tea requires you to look out for the following:

  1. Caffeine content per cup

  2. Tea bags vs. loose leaf

  3. Quality of Leaf

Total Caffeine Per Cup

A high-caffeine tea’s caffeine level per cup is the most important factor to consider. The amount of caffeine that you will receive in each serving will not be listed on the packaging, but look around the packaging for either a visual indication or a direct reference to the amount in milligrams (mg). If available, look for a strength indicator on the label. This will indicate the strength of the tea.

One dot is considered low caffeine (around 20–40 mg) while three to five dots are considered high caffeine (around 90–130 mg per cup).If you are taking a strong blend that goes up to around 130 mg per serving, we strongly recommend that you consume only about 2–3 cups per day. Remember: caffeine can cause a lot of unwanted symptoms!

In addition to keeping you awake for longer, it also directly affects your heart health and can affect your digestive system, causing a range of separate symptoms.

Loose Leaf Vs Tea Bag

There are two main types of tea available: bagged and loose. You should use loose leaves and a quality tea strainer or infuser if you are old school and like to brew your tea carefully.Since tea bags eliminate the need for clean-up and are highly convenient, they are a godsend for many people.

It’s as simple as adding the tea bag to a cup and letting the leaves steep in hot water for a few minutes to get hot tea instantly!

Making large batches of tea with tea bags can be tedious, and it isn’t the traditional way to brew tea leaves, which is why some purists abhor it (especially during guests’ visits).

Choose the right type of tea for your daily needs, no matter what your reasons are. It is better to choose loose tea leaves if you want to steep and brew your own tea, or if you make large batches of tea.

Leaf Quality 

It is important to make sure that you are getting the most value from your tea, regardless of what type you choose. The problem with cheap tea is that it will contain shredded tea leaves, whether in a bag or loose form. The more the tea leaves are processed, the more their inherent quality and flavor is lost.

In general, if you buy a highly processed tea, you aren’t going to get good quality leaves – sneaky manufacturers might even mask the flavor of the tea by adding unnecessary chemicals and stabilizers! Ensure the packaging is detailed and select manufacturers with a great reputation so you get the best experience.
