The things I know about Tea Cart is their events. You see events quite often listed - They are basically themed teas. (I've been to one - it was great fun! I've wanted to go to others, but haven't made it out yet.) The staff is quite knowledgeable, the teas and the atmosphere are great! They are a great tea house!
Quaint little shop - You wouldn't believe it was here if you did not know. What seems like a decent selection of teas and coffees. It is quite small inside, but there are tables on a patio that you can sit at when the weather is nice. Definitely worth a visit if you are in the area.
Brew Loco has several options for drinks that are brewed. (Coffee, beer, tea, etc) I've had some great drinks from this location - (and bought adagio tea from here before I knew that brand was a thing actually). The people have always been great when I stop in. The downside (at least to me) is that I wish they were open earlier in the day. It would be nice to be able to stop on my way to work to pick up a cup of tea or coffee. And they are closed or near closing when I come back through in the evenings. Other than that minor qualm, I definitely recommend giving Brew Loco a try!
Modern tea shop in downtown Purcellville. Great teas, knowledgable staff. You can go in and have a cup there - or get one to go. The walls are lined with the tea options - so you can smell each tea before deciding. If you are still between what you'd like, they offer a "tea flight" you get three teas to taste. (You can choose your own or go with their "flight of the month".) When I am undecided, I've gone with the option to let the tea expert that is working pick what tea I have that day a few times. It is a nice way to break out of my comfort zone and try some new things. If you are in this area, definitely give them a try.
