What Is the caffeine content in tea?

Never Underestimate the Importance of Being Properly Caffeinated

The caffeine content in tea changes considerably from things as simple as the type of tea you are consuming to as complex as the part of the leaves being used to make the blends. There are many myths in regards to the caffeine content in tea, such as, white tea contains less caffeine than green tea, and black tea is the strongest tea. Read below to learn more about the caffeine your consuming in your daily cuppa!



The amount of caffeine in pu'er tea can vary greatly due to the fermentation and aging process. The more aged the pu'er, the better the flavor—and the stronger the caffeine. Generally speaking, the raw production process yields less caffeine than the ripe process. You can expect a black fermented pu'er to yield 60-100 milligrams of caffeine per 8-ounce cup, potentially making this the strongest tea. In contrast, green/young Pu'er tea yields 30-45 milligrams of caffeine per cup putting it closer to a cup of white tea. Check out our Black Walnut and Berry Truffle Pu'er Teas for a nice jolt in the morning! 



Black tea almost always ranges on the higher side of the caffeine spectrum sitting at 55-75mg per 8oz cup, followed by oolong tea. However, many factors determine caffeine levels in any individual cup. The more concentrated and longer the steep time, the more caffeine in the teacup. And while most black teas, like our Darjeeling, (the Champagne of the tea world) and our Creamy Vanilla can be steeped multiple times, the caffeine content will lessen each time it’s steeped.



The caffeine content of oolong teas falls somewhere between green and black tea. A lightly oxidized oolong tea is more similar to a green tea and may have a lower caffeine content (around 40-50mg), while a highly oxidized oolong tea may have a higher caffeine content (50-75mg), similar to black tea. The caffeination also varies depending on the cultivation process. Check out our Lemon Rose, Peach and Jasmine Mist Oolong Teas for a few of our fan favorites. 



Chai tea is traditionally just black tea blended with spices, milk and sugar. With that being said, most chai teas fall around the 30-50mg mark for an 8oz cup depending upon which black tea is used in the blend. You will likely see Assam or Darjeeling Teas as the base for many of the chai teas out there today. If you're looking for a few unique chai teas to try, look at our delicious and refreshing White Chai as well as our Spicy Bengal Chai



In general, you can assume that an average 8-ounce cup of green tea will yield anywhere from 35 to 50 milligrams of caffeine, like our Pomegranate Rose and Strawberry Stunner Teas, with the exception of Matcha, which sits at around the 70mg mark. The longer the steeping, the higher the caffeine. However, I don't advise steeping green teas for longer than 2 minutes until the second steep. While all of our teas can be steeped multiple times, the caffeine content will lessen each time.



White teas are diverse and have a wide range of caffeine contents ranging from 15mg a cup to 70mg a cup. Most of our white teas have the least amount of caffeine. This is because the original Fujian white tea plant from China is lower in caffeine compared to other tea plants. However, some studies have shown that white teas, such as Silver Needle, may contain as much caffeine as green or black teas depending upon where and how they were cultivated and processed. Georgia Peach, Sweet Strawberry Kiwi and Fountain of Youthful Berries are 3 light and bright teas!



Rooibos and herbal teas are entirely caffeine-free—with the exception of blends that mix Rooibos with other teas, such as our Mate Tiramisu, which combines the South African brew with black tea and yerba mate. Don't forget to check out Florida Citrus Lavender Sage, Calm Night, Cozy Comfort, Turmeric Herbal, Tropical Orchard and Caramel Brulee.

Tea became part of my life at a young age. When I couldn't sleep and needed to talk, my mom made us a cup of tea and we would stay up talking and eating pancakes. As I got older, my dad and I would meet at cafe's for tea, but we quickly realized we wanted SUPERIOR quality, with better flavor and couldn't be found in a teabag. After much research, Grey & Bash Teas was founded and named after my sons, Greyson and Sebastian. Grey & Bash now includes, my husband, sister, father and a bonus sister. We are a family owned and family run business, which means we treat YOU like family!
