Try loose leaf tea, specifically roasted oolong, black teas, or pu erh. r/tea has a good wiki on which reputable vendors to buy from [0].

Will take a look!

You might enjoy roasted dandelion root tea. The taste is about as earthy as it gets. Also, as a bitter herb it's great for digestion.

It tastes nothing like coffee though. It tastes like other things that kind of taste like coffee, like chicory. They taste sort of like coffee and dandelion sort of tastes like them, so it's a little too removed.

Will try!
