Understanding Tea and Caffeine

In Tea Health Benefits by teadog.com4 Comments

Do you know how much caffeine is in a cup of tea? Most tea drinkers are confused. Caffeine occurs naturally in coffee, tea and cocoa beans. It is added to cola to enhance flavor.

Since black and green tea come from Camellia sinensis, the tea plant, both contain caffeine. Most herbal teas are made from herbal blends and contain no real tea. As a result, most herbal teas, such as chamomile, are caffeine free. Red tea or rooibos, a South African herb, contains no caffeine and has many of the health benefits as green tea. Honeybush tea, another increasingly popular herbal tea, also is caffeine-free.

On average, a cup of tea contains 1/3 the caffeine as a cup of coffee. According to the USDA, an 8 ounce cup of coffee brewed with tap water has 137.7 milligrams of caffeine; an 8 ounce cup of tea brewed with tap water has 37.5 milligrams of caffeine; a 16 ounce cola has 49 milligrams of caffeine.

Caffeine levels in tea bags and loose tea are similar. The amount of time you steep the tea is the biggest factor in determining the level of caffeine. For a good and high quality black decaffeinated tea, try Bewleys Decaf tea, PG Tips Decaf tea or Typhoo Decaf tea.

Here is a tip in case of emergency and you are without a decaffeinated teabag. First, place a standard tea bag in a cup and fill with boiling water. Then, let the tea steep for 30 seconds and discard the water. Most of the caffeine in tea in released in the first 30 seconds. Next, place the tea bag back in the cup and re-fill with boiling water and allow to steep for 3 to 5 minutes. Now, you had a good cup of tea.

  1. You forgot to mention the weight. You must specify grams not only brew time. Unit dose is crucial

    Actually, it is not possible to "decaffeinate" tea the way this blog post suggests. This is a myth and I personally have tried it with different types of tea, with different amounts/weights of tea, and for different steep times, and it does not work. All that happens is that you get an extremely weak caffeinated tea, much akin to types of tea made and consumed in Asian countries non-Western style, and it's not actual decaffeinated tea.

    Most of the caffeine is NOT released from a tea bag or tea leaves within the first 30 seconds. The longer you steep the tea bag or tea leaves, the more caffeine you will get. Water temperature also plays a part in this, the weight/amount of the tea, as well if the tea is black, green, white, oolong, etc.

    Even decaffeinated tea, and coffee have caffeine in them but it's in extremely low amounts so most people do not notice it at all.

    John;

    Thanks for the response. We have written about this a long time ago. But, recent research has proved this to be false. It doesnt actually decrease the caffeine at all. Thanks again.
