WHAT’S NEW

Caffeine in tea is a top concern when choosing what to drink: Will tea keep me awake? Is it gentler than coffee? Which tea has the least caffeine? In fact, tea leaves naturally contain caffeine, and the amount varies widely depending on the type of tea, where it's grown, and how it's brewed. This article covers the caffeine content of each tea type, how tea differs from coffee, the recommended daily limit, and brewing tips to reduce caffeine.

Black tea is one of the most widely consumed teas globally, and among its many varieties, Earl Grey and Assam are the two most renowned classics. While both share a "black tea" base, they possess entirely different flavor profiles and cultural backgrounds. This article will take you on a deep dive into the origins, characteristics, and best applications of these two tea powders.

The most familiar way to drink tea is by steeping tea leaves — hot water is poured in, the leaves unfurl, and aroma and flavor are released. But you may not realize that traditional steeping actually releases only a portion of the nutrients and flavor locked inside the leaves. A large amount of these compounds remains trapped in the spent leaves and is ultimately discarded. This is precisely why tea powder has been gaining attention.

The quality of tea powder is largely determined the moment the tea leaves arrive at the factory. No matter how precise the later processes are, if the raw material itself has problems, the aroma, flavor, and safety of the finished product are difficult to fix. That is why raw material selection and inspection is the one step in the tea powder manufacturing process where no compromise is acceptable.

How Much Tea Powder Should You Add? Recommended Usage Rates by Product Type

Two people can use the same bag of tea powder and get completely different results: one enjoys a fresh, naturally sweet cup, while the other tastes bitterness and finds clumps at the bottom. More often than not, the difference comes down to temperature. Tea powder is made by grinding the whole tea leaf into a fine powder, so catechins, caffeine, amino acids, and aroma compounds are all concentrated in every spoonful. If the water is too hot, bitter catechins and caffeine are released in large amounts and delicate aromas evaporate quickly. If the water is too cold, the powder struggles to disperse, clumps easily, and the flavor never fully develops. Getting the temperature right protects flavor, color, and texture at the same time.
