Hello hello! I'm new to the world of loose teas as well! Teas are much more vast and complicated than I had originally thought, but they're wonderful! The first real loose tea I ever started drinking was Iron Goddess Oolong; a lovely mild and floral tea. I highly recommend it! But if you're not ready to dive into the Oolong teas, I'd go for green and/or some of the flavoured teas, since they're lovely and mellow and enticing.
