The white tea is already familiar to me, and I can tell it's really good. Haven't tried the other two yet.
The sencha okumidori smells fantastic, so I have high expectations. Sadly, they didn't have any gyokuro at the moment. Otherwise I would have bought that. Regardless, I don't think this sencha will disappoint me.
Maybe I'll start with the oolong tomorrow. It's been close to a year since I had any, so I kinda miss that taste. All I know about this oolong is that it's from China, which is a nearly useless description IMO. I guess it's going to be a bit of a surprise then.
