Oh Yes Tea

While in Chicago for a weekend trip, I visited several tea shops – it was nice to see leaf tea is gaining popularity, at least in some parts of the U.S. There is certainly much to do in terms of quality of education in general leaves different – I'll write another article on this subject, I hope I can take physical samples soon. I'm back with what seems an infinity of new things to tell, but for now let's dispel the rumors about caffeine in tea. We into account levels of caffeine in different parts of the tea bush, absorption, flavor, and differences of caffeine in tea and coffee.

Start some basic facts from the beginning …: The amount of caffeine in tea leaves dry bulk exceeds the amount of caffeine in the same weight of grains dry coffee. The content of caffeine in a cup of tea, on average, less than half (approximately) the same size as a cup of coffee. This is because the longer the tea is produced from the same amount of tea leaves coffee beans. Brew tea beyond the recommended soaking time increases the content of caffeine in the cup, which is something I do not recommend – the taste of tea will be affected to varying degrees (the main contributors to the flavor of tea is due to the interaction between caffeine and polyphenols in the leaves).

So, in short, a cup of tea yields generally well developed around half the caffeine content in a cup of tea.

Caffeine content of bush tea varies depending on the part of the forest for their use tea leaves bulk. Well that caffeine levels vary slightly by region, the overall distribution of the caffeine content is as follows:

Bud 4.50%
First leaf 4.10%
Second sheet 3.40%
The third sheet 2.90%
Upper stem 2.50%
Stem below 1.40%

Depending on the type you drink tea (white tea, for example, is just before the outbreak, high in caffeine). Many high-quality teas in bulk quantities lower leaf higher net bars, resulting in a decrease in the caffeine content of tea. This is important, remember, because the flavor is a matter of vital interaction between caffeine and polyphenols in tea). As for daily consumption is concerned, it is generally safe (and do not know – at least what I found in my research) to consume as much as 10 to 12 cups of tea per day. I should add a word of warning, though …. Tea is a diuretic, for its caffeine content. You will to take more water to offset fluid loss caused by drinking lots of tea. I realize that may sound strange, but just try! Drink a cup of real leaf tea, and you will find yourself feeling dehydrated after an hour. Of course, this is not the case of the garbage that passes for tea (Lipton Iced tea thinking, for example).

To better illustrate the amount of caffeine in different drinks, here are some comparisons:

Coca-Cola Bottle (300ml) – 40 mg caffeine (average)
Dark Chocolate Bar (50g) – 35 mg of caffeine (AVG)
Coffee (8 ounce) – 100mg (AVG)
Tea cup (8 ounces) – 35mg (AVG)
A pharmacologically active dose of caffeine is 200 mg and a lethal dose of 10,000 mg. Important to note here is that several Studies suggest that 70-80% of caffeine actually consumed is not absorbed by the body.

Here's another for you: the content of caffeine in tea green is about the same as black tea. The fermentation process in a critical condition of the final leaf (green or black) does not affect the active catechins (antioxidant) the content of the leaf, but the caffeine content is almost equal. So …. when the store clerk told you that green tea contains less caffeine not take the floor. Keep the water temperature and infusion time recommended, and have a nice cup of tea – with a half dose of caffeine than coffee, and not detrimental to their (health warning rule applies here, if health problems consult your doctor).

On the subject of decaffeinated tea: It is likely it deserves its own theme, but at least you have a reference bit. There are three ways to extract caffeine from tea leaves trade in bulk, including solvent (either ethyl acetate or methylene chloride) or the use of carbon dioxide. While producers insist that affects the road shortly, will be having tea with less than 0.4% of caffeine (the maximum level of caffeine in dry tea leaf decaffeinated). Here again, as a purist, I would mention that the flavor of the interactions will affected, and uses a modified product by the use of foreign chemicals. Buyer beware.
