Teas with caffeine in them

Black teas are generally going to have the highest caffeine content, but even then it's likely to have only half as much caffeine as an equivalent amount of coffee.

What teas have you tried before that you disliked?

Yeah black teas. I like Earl Grey and Vanilla Bean. I use Mighty Leaf: https://www.mightyleaf.com/

Actually, black tea has the least amount of caffeine of all the varieties produced from tea plants. Green tea has quite a bit more, white tea has the most. I would not recommend starting with greens and whites, though. Get a number of good black teas from different countries/regions/tea gardens to find out which flavor profile you like, then go on with green and white tea. A black Darjeeling (Steinthal is a classic garden) Assam and a high quality broken blend will do to get the basics covered.

Try loose leaf teas:

Huge difference between the crap you find in grocery stores.

This is a good read if you want to know all the basics:

Drink loose leaf tea for taste. So many possibilities.

Then take low dosage caffiene pills in set amounts equivalent to a cup of coffee you used to take.
A nice pill cutter will last you.

I don't believe this is correct. Where did you get your information? Black tea equals highest caffeine content has always been my understanding.

Both of you are wrong.

The amount of caffeine in a cup of tea is primarily determined by volume and seeping time.

The growing methods affect how much caffeine is in a particular variety of tea, whereas oxidation has no effect.

I enjoy tea and drink several cups each day. It gives me a bit of energy but it's a much more subtle boost than coffee.

I don't really know about caffeine content but if you want a potent, flavourful brew try a Lapsang Souchong - very smoky and delicious. I've been drinking lots of oolong lately - Ti Quan Yin is great. I'll drink pretty much every type though and a good English breakfast tea is really nice in the morning.

Do you have a local tea shop or high-end grocer? If not, you can buy online. Mariage Frères make some of the best blends I've tried and have a huge variety available for purchase online. Not cheap though and you have to order a lot to make it worthwhile because shipping is pretty expensive as well.

Yeah, no. I'm right.

Looseleaf tea is the best, my preference are black teas. But since you aren't sure what you like I suggest you get tea bags, something mainstream and relatively inexpensive like tazo or twinnings. Black tea has the most caffeine and tastes the best IMO, I dislike green tea for the most part.

You are still wrong.

Compared to green/white teas, black tea is typically seeped longer with a larger amount of leaves.

I think you mean steep. But are you suggesting the Mayo clinic is wrong? Why would they lie to us?
