I’ve heard there’s more caffeine in tea. Coffees do feel stronger than tea, I wonder if that’s due to oil in coffee working as a solvent

  I've heard this too but need to see the numbers. I wonder if it's the caffeine per dry weight or per brewed serve. But don't get me started on what a serving of coffee is.

  Every tea is different. Black teas have more caffeine than green, for example.

  A cup of coffee has way more caffeine than tea. Coffee has 163mg per cup, black tea 42mg and green tea 25mg.[0][1][2] 1kg of dry tea does have more caffeine than 1kg of coffee beans, according to Wikipedia[3] > Tea contains more caffeine than coffee by dry weight. A typical serving, however, contains much less, since less of the product is used as compared to an equivalent serving of coffee. Also contributing to caffeine content are growing conditions, processing techniques, and other variables. Thus, teas contain varying amounts of caffeine Also kinda interesting: I've often seen people opt for an espresso instead op a cup of coffee, because they say they need the caffeine. But an espresso has only 77mg of caffeine, way less caffeine than a cup of coffee. [4] (Unless you fill a coffee cup with espresso shots, but who does that?)

  According to Mayo Clinic, typical caffeine levels are: Brewed coffee (8 oz): 96 mg Brewed black tea (8 oz): 47 mg Brewed green tea (8 oz): 28 mg https://www.mayoclinic.org/healthy-lifestyle/nutrition-and-healthy-eating/in-depth/caffeine/art-20049372 https://www.mayoclinic.org/healthy-lifestyle/nutrition-and-h... It's worth noting that tea also contains theanine, in addition to caffeine. Theanine binds to glutamate receptors and increases serotonin, dopamine, GABA, and glycine levels in various areas of the brain.

There is considerable amount of caffiene in tea as well but it’s absorbed slower by the body than from coffee and most tea has L-Theanine, which is an amino acid which attenuates the caffiene high that is usually present from coffee.
