As I state in my other Adagio reviews, they were my first experience with loose leaf tea back in 2005, and I still purchase from them. Their blends are usually of a decent quality and the relationships they have with the farmers is awesome. Their customer service is usually top notch too.
The citrus green posted is a Japanese Sencha base accented with orange and lemon. When initially steeping, it can seem to have a kitchen cleaner aroma, but as the tea cools to drinking temperature so does that association. It's a bright tasting cup with a clean finish. No strong artificial associations, and would also be very good iced.
