Example Input: I was looking forward to this tea, but unfortunately the mint overpowers the hibiscus and essentially makes this just another kind of mint tea.  I prefer the hibiscus tart be the star of the show in a hibiscus-based tea (aka "herbal infusion") and in my opinion, mint and "tropical" don't mix and now know going forward to pay more attention to the ingredients.  Still worth 3 stars because it can be a refreshing tea on a hot day, but just not a great tropical/hibiscus tea.

Example Input: I really like this granola - their hemp granola is my favorite. REALLY good stuff. However - it's just too sweet for my taste. Most granola is dreadfully sugar-laden, and other than the healthy ingredients, I feel like I'm chomping on some commercial-grade grocery store sugar cereal... -___-  That said, the texture is very satisfying and it is tasty. Just a bit sweet. You've been warned.. ;)
