It was interesting learning about and trying the different teas, or rather the manufacturing process to produce different teas. As far as the tasting, I personally found them to be a little bitter, but I'm not really used to drinking unsweetened tea.
Mixing the teas is a cool idea, the bitterness also pretty much went away after putting them in the bags. However, I felt like the options available didn't really produce drastically different flavors. I think this may be more for people who are into traditional teas.
The rice with tea was better than I expected. On its own it was fairly bland, but the toppings helped add flavor, and I ended up liking it.
