Best High Caffeine Tea - Green and Black High Caffeine Tea Bags, K-Cup Pods and Loose-Leaf Teas

You’ve been told repeatedly how great a substitute high caffeine tea is for coffee, or how much of a healthier option it is. You’ve decided to give it a try but are faced with thousands of products in the market. To give you a base of comparison, the average cup of coffee has about 95 milligrams of caffeine, but this varies by type and brew strength. How do you go about determining which product’s claim is authentic? We know that products like high caffeine tea are such that some people may just do a “mini mini mo” to select one and at the end of the day may regret their choice. That’s why we’ve taken our time to do thorough research to find five of the best high caffeine tea brands out there.

When selecting brands, we had several criteria, the first of which was a solid reputation for quality teas. The second criteria was that the brands needed to have multiple options. This is important because we understand that caffeine level doesn’t matter if there isn’t a flavor you like. While we only chose one specific product to feature, we also include information about other flavors and links within each review.

So, if you don’t like the tea we picked, make sure to check to see what else they have to offer. And if you are looking for loose black tea blends, we also recommend taking a look at Tiesta Tea High Caffeine Energizer Teas which come in a variety of flavors. Pure Matcha green tea powder also has a high caffeine count (about 50 to 75 mg per teaspoon).

One more thing before we move on. For this review, we focused on what would be considered “traditional” blends with either black or green teas. However, many people are turning to Guayakí Yerba Mate tea made from the naturally caffeinated leaves of species of tree that grows in the South American rainforest, Paraguay, Argentina, and Brazil. Each cup has strength of coffee (about 40 mg), the health benefits of tea, and the euphoria of chocolate. You may also like David’s Tea Jumpy Monkey which is a delicious blend of roasted yerba mate, green yerba mate, green coffee beans, cocoa nibs and white chocolate. Mmmmm, yummy!

Price

There’s a wide variety of high caffeine teas in the market: from single blends to exotic mixes, some with high caffeine content and others with low to medium caffeine content, some sourced from far away climes and others from our own backyards, some packaged with biodegradable sachets and still others with recyclable tins/containers. All these factors surely affect the price of the end product.

A good quality high caffeine tea can be bought between the price range of $12 and $45, partly depending on its quantity. During our research, we came across some cheap high caffeine tea, but they didn’t make the cut because they didn’t have enough caffeine to be featured as high caffeine tea. That said, whatever product/brand you choose based on this review, it’ll surely afford you good value for your money.

Features

High caffeine tea is a great substitute for coffee for a lot of people, namely those who might want the caffeine kick, but who could do without the jitters and crash that accompany coffee intake. Those who also suffer stomach disorders or other side effects from coffee consumption are presented with this great alternative. There’s a wide variety of teas in the market that are caffeinated, but you still need to note some features of high caffeine teas so that you’ll be able to make an appropriate choice when you go shopping. Here are some of the features to look out for:

  • Quality and source of ingredients in the blend
  • Percentage of caffeine in the blend
  • Preparation/ brewing time and method
  • Packaging and storage after purchase
  • Flavoring and the use or not of sweeteners and milk
  • Full disclosure and understanding of ingredients in the blend
Construction and Design

Pure tea is a product of the leaves of an Asian plant known as Camellia sinensis. All the variations are derived from it and they all have caffeine. Studies have shown that caffeine works in plants as a natural defense system to stop insects and other plant devouring creatures from eating them with its bitter taste and stimulating properties. It’s not too surprising to note that it’s the fragile buds that are just forming and the young leaves of the tea plants that produce the highest quantity of caffeine.

There have been a number of researchers that claim that caffeine has many health benefits. That said though, remember that moderation is key in anything in life. Here are some different tea types and their properties/benefits:

  • Green tea if taken frequently can improve your immune system; it has antioxidants that help fight infection
  • Peppermint tea reminds one of peppermint mocha and latte, but it also works well as a natural decongestant and is great for clearing sinuses and calming sore throat
  • Ginger tea is great for indigestion and helps to ease nausea
  • Black tea doesn’t have as much caffeine as coffee, but has more than other types of tea. This makes it a good substitute for caffeine fix/pick-me-up on those occasions when you don’t want coffee to keep you awake at night

Performance and Ease of Use

The preparation or brewing of tea is a pretty simple task. However, the type or brand of tea may require additional time and utensils.

Loose leaf tea, whether rolled up or left as is , requires that you wait a little longer and a tea infuser to get the leaves out of your tea before consumption, while a simple tea bag merely requires that you steep it in hot water for the stipulated time to get the right taste.

Because of the minimal processing that goes into packaging a loose leaf tea, it retains more of its natural properties and stays fresh longer than the tea bag, and also allows more flavor and taste to be infused as you brew it. If you’re particular about the taste and freshness of your tea, you might forego the convenience of a tea bag and go for the loose leaf tea. It should be noted, however, that loose leaf teas are usually sold in large quantity and mainly by specialty tea stores; you don’t get them in your regular grocery stores. Truth be told, how many of us are that particular about the little difference in taste and flavor? If you’re not one of those tea connoisseurs, why not go for the convenience in purchase and preparation of tea bags? In any case, the final choice is yours!
