A friend swears there is 10x more caffeine in tea than coffee, yet I am always told a cup of tea has fractions of the caffeine found in a cup of coffee. This paradox is confusing, please help…
Your friend is rationalizing his/her coffee habit: It isn’t 10 times - by weight, black tea has twice the amount of caffeine found in coffee – green tea has about 1.5 times caffeine total as coffee does, putting 8oz of green tea on par with a 12oz can of soda. And those are rules of thumb; Robusta beans contain twice as much caffeine as the connoisseur preferred arabica beans; drip coffee will extract more caffeine than French Pressing the beans. And espresso, whose serving potions are smaller typically use dark roasts that burns off caffeine and its brewing method leaves little time to extract caffeine, as a result your demitasse has about ½ caffeine as your standard cup of Joe.
Caffeine is a drug, hand’s down the worlds most used drug – sorry hemp enthusiasts. It is an alkaloid, like opium and cocaine, which has some researchers in the forefront addiction studies trying to piece where or how alkaloids belong in the addiction puzzle. The science, as we understand it now, tells us that caffeine travels to the brain via the blood stream and it displaces the neurotransmitter, adenosine – a chemical in our brains that slows down nerve impulses. It takes about 15 minutes for caffeine’s effect to begin, 30 to reach its peak and from there it takes over 3 hours for the levels to subside. Go over 350 mg per day and you run the chance of becoming dependant, 6 cups of coffee a day or 3 No-Doz puts a person at risk of heart palpations, insomnia and loss of calcium in your bones, but on the upside it does amplify the effects of the drug. 6000 milligrams at once should be enough to provide a horrible, frightening, hyper-aware death.
As a flavoring component, caffeine gives off a bitter taste. It is just one of 300 flavor compounds found in tea. Also present are chocolate’s narcotically good theobromine – along with trace elements of fluoride, vitamins, minerals and proteins. Tea leaves also contain the amino acid theanine, which is believed to act as a neurotransmitter, allowing for a person’s relaxed state despite the presence of caffeine – there is a paradox that should [mess] with you. Brewed tea is rich in antioxidant phenolic compounds, materials credited with strengthening artery walls, protecting against cell damage and lowering the risk of cancer.
Because of this, the taste or the social aspect of drinking tea, it is be the second most consumed liquid on earth after water. Deluxe, premium, rare coffee will set you back about $30 a pound. Good but not great tea will cost twice that - Again with the rule of thumb(s), a person can expect to get 200 servings out of a pound of tea (6,000 individual leaves), so tea ultimately ends up being about 1/3 of the cost of coffee.
