Why does caffeine taste bitter when added to tea?
Black tea contains about 40 mg of caffeine. When adding 80 mg of caffeine powder, the tea tastes bitter.
Why doesn't caffeine that is already in the tea or in an energy drink taste bitter and how should caffeine be added to drinkable fluids so it has no taste?
Adding more sugar is not a very healthy solution either...
Best Answer
Caffeine is bitter, tea isn't too bitter because as you mentioned it's only got 40mg of caffeine. If you then triple the amount in there it's going to taste that way. Try adding 3 tea bags to your cup and I'm certain it'll taste just as bitter.
Energy drinks have copious amounts of sweeteners added hence why they don't taste like caffeine.
If you are hell bent on more caffeine without the associated bitterness but not adding sugar maybe a sweetener like stevia would be the way forward...

Answer 2
"The addition of “phantom aromas,” such as vanilla, berry, citrus, bacon or even cheese, can distract the brain from acknowledging a bitter to taste." "Other additives can mask or “mitigate a bitter taste.” Lactisole, for example, made from carboxylic acid salt derived from Columbian coffee, can negate sweet taste. An allosteric modulator can change a food or ingredient’s protein structure reducing the salty, sweet or bitter signal to the brain." src -http://www.novotaste.com/content/bitter-blockers
Substitute some of the supplemental caffeine with theanine, and add only Xylitol (possibly steviol but to me the taste is disgusting). Don't forget some glucose-based sugars for consistency (it considerably affects aftertaste). Add a pinch of potassium-balanced salt. Lemon juice helps the bitterness too if that is an option for you.
Answer 3
Tea also contains tannins, which is the main cause of the bitterness - not the caffeine.
You're adding something bitter to something that's already bitter, obviously increasing the bitterness, so I'm not sure what the point of the question is. The question should have been, "how do I mask the bitter taste of added caffeine in my tea".
Milk, sugar, acid (such as lemon juice), and salt are all suitable for masking bitter flavors.
Answer 4
EDIT: The tea without the added caffeine does have bitter flavor to it, but you don't notice it because "noticing bitter" means there's "too much bitter" in the flavor profile. The tea tastes good because the bitterness in it is balanced by other flavors—and that balanced bitterness is part of what makes it taste good.
As for the second question, you can't. Caffeine has a flavor, and it will add that flavor to whatever you add the caffeine.
For a similar example, I can taste the difference between Mountain Dew and Caffeine Free Mountain Dew. I prefer the caffeinated version (slightly), because the bitterness of the caffeine balances the sugar better. The caffeine free version is a touch too syrupy, leaning very slightly towards root beer. But there's a ton of caffeine in Mountain Dew, which is why I can taste it over the sugar at all, and even then it's not strong. Contrariwise, I don't like Mountain Dew Throwback at all (the kind made with sugar instead of HFCS). It's not sweet enough, and too much acid and bitter shine through.
Chocolate is another obvious example, not as much from the caffeine as the cacao. I like semi-sweet chocolate because the flavor profile is more well-balanced than with milk chocolate (the sweetness doesn't totally mask the bitter flavor), and tasters almost universally prefer cookies made with semi-sweet chocolate when the cookies are already loaded with sugar. Supertasters seem to like chocolate that's much more bitter than an typical taster can stomach, but I don't know why.
