Hooray for all of the tea-lovers in the forum! 
Several people already mentioned getting a tea sampler- I agree that is a great way to try out a bunch of teas without having to worry about getting stuck with one you don’t like! 
If you have a tea store like Teavana near you, oftentimes they have ready-made teas for you to sample (although covid may have ruined the samples!), it’s a good way to try a bunch of teas for free 
If you have an herb garden, you may be able to make some tasty teas with the plants you are growing! 
There’s a great discussion about healthy and magickal “green” teas here and you can check the list of Tea Meditations on Spells8 to help you learn the magickal properties of teas as you try them 
Also, I can’t help but add that all tea-lovers are warmly invited to the weekly Group Tea Ritual held in A Sacred Space (the ritual for the week is uploaded every Tuesday and the ritual runs every Thursday). Come share your brews and show off your favorite teas! 
Good luck, @MoonDrifter18- I hope you can find some wonderful new teas that you enjoy!
