 Caffeine in Green Tea

caffeine in green tea

The leaves harvested for green tea are from the same Chinese tea plant that black and oolong tea are harvested from, hence why the green tea leaves still contain caffeine. So why then, do the teas differ in appearance, taste and caffeine content? Black Tea and Oolong tea are put through an age old withering and oxidation process, which breakdown the leaf proteins that release more caffeine; therefore changing the taste of the tea and the caffeine content! Who’d have thought it?

Drinking green tea is consistently linked with a healthy lifestyle, with the high content of antioxidants and no more than one calorie per cup, it’s no wonder we’re always salivating over the delicious range of green teas available at Whittard of Chelsea. Jasmine, Goji Acai, and Mango & Bergamot are just a few of the popular fragrant choices available online – so there’s plenty of choice for those of us who find the taste of plain green tea too bitter to stomach on daily basis. Just remember; if you’re trying cut down on your caffeine intake, opting for naturally caffeine-free herbal teas is the better choice, not to mention just as good for you.

Refreshing and beneficial to the digestive system – why not replace your cups of green tea with a herbal peppermint one?

Caffeine in Earl Grey Tea

It’s time to get to know your cup of Earl Grey a little better. A black tea blend of Ceylon and Chinese tea with bergamot flavouring – Earl Grey became iconic for its simply divine taste when paired with the sweet indulgence of afternoon tea. As a combination of black teas – Earl Grey naturally contains caffeine. The bergamot oil adds the distinct refreshing citrusy taste and aroma we all love Earl Grey for!

The Whittard blend is a quintessentially British delight – try the loose-leaf version with its pretty blue cornflowers, paired with a big ol’ slice of cake. Delicious.


Caffeine in Rooibos Tea

You won’t find any caffeine in Rooibos Tea, more commonly known as Red Bush tea. Although a fairly recent addition to our tea selections at home, ‘Bush Tea’ has been enjoyed in South Africa for generations. Usually grown in a small mountainous area of Cederberg in South Africa, Rooibos has malty, honeyed taste and can be drunk with milk like black tea, or with honey, lemon or sugar to taste.

Rooibos is naturally caffeine-free, and also contains much lower levels of tannin than black tea and green tea (the compound that stains your teeth over time), making it the ideal alternative to your regular brew. It’s also the perfect comforting cuppa’ to wind down with before you head upstairs to bed – with not a gram of caffeine in sight! Whittard have a dreamy selection of plain and flavoured Rooibos tea, guaranteed to tantalise your taste buds in caffeine-free bliss.

 


Caffeine in Matcha Green Tea

The Japanese super tea; the healthy green powder packed with flavour, antioxidants and a generous caffeine hit too. Woven into Japanese history, notably in Zen Buddhist practices, Matcha Green Tea has fast become the healthy drink to drink. Healthy tea does not means free of caffeine, with around one cup of Matcha Green Tea contributing 70 mg of caffeine to your daily intake – on par with most Black Teas. The ground up leaves form a powder that promotes quick absorption of all the goodness inside the tea leaves, properties that often aren’t extracted in great quantities by brewing.

Matcha Green powder can be drunk in a traditional way with hot water, or swirled into a Matcha Latte with hot milk. Make Matchas that would earn the respect of the Japanese, with Whittard’s traditional bamboo spoon and whisk to make sure you achieve the creamy froth on top! A great gift for any Matcha tea drinker.
