Taking this idea further, one could add multiple orthogonal axes (eg sweetness, bitterness, after-taste etc). Then you could rate each tea against others on each axis - either in a star-slider, scatter plot or on several individual sliders. This would allow you to rate teas against each other based on several aspects, and possibly allow recommendations based on how other people have rated teas - eg 'I want a tea that is not-too-sweet, a little bitter with a lingering aftertaste' Then again, it does add more features / visual clutter and possibly complicates things for people...
