The figure's largest circle is tea. What kind? Any kind?



Most people don't realize that most varieties of tea come from the same plant https://en.wikipedia.org/wiki/Camellia_sinensis

Your question is still a good one, but hoping the above context makes the "so tea as a blanket category just... works?" less absurd.


We don't know if the processing steps for green tea vs black tea removes or adds to the beneficial quantities.


Accidentally took a workshop on this at a tea festival a number of years back.

Turns out the “fermenting” of tea is mostly self contained. Autolysis, I think might be the word?

If you recall that caffeine is an insecticide this makes sense. The caffeine is stored as a time bomb waiting for some insect to chew. Mastication mixes the caffeine crystals and the enzymes already present in the leaf, which then render it soluble and bang, dead insect. To process tea you just need to activate the enzymes the right amount at the right temperatures, and then dry the leaves before they can rot.

If you get a proper oolong loose leaf, and let it steep long enough, you will find what looks like whole leaves in your cup. Not unlike those little dinosaur sponges they sell to kids. Just add water.


You can also grow it yourself. Just bought 2 plants


Interesting, can you realistically get good results from that when growing it in mild climate like US or Europe? Indoor? Greenhouse?


Yes. There are now a small number of tea plantations in the UK from Cornwall to Scotland. All outdoors

Even one in Sweden -

It takes about 3-5 years to first harvest though
