That's a very savvy perception. Or maybe I'm just calling it savvy because I agree. Great minds think alike, LOL.
The more reviews I do---not just for the RY4 thread, but for other juice flavors also---the more clearly I experience that distinction. Liking a nicquid (or conversely, not liking it) does seem to be almost entirely personal and subjective. Appreciating a juice, however---which is to say, recognizing the quality and care that went into its making---is still personal and subjective to some extent, but calls forth another layer of perception. To call that additional layer "objective" is probably an exaggeration, but it definitely invokes a cooler, more detached assessment, like being a fair witness.
For instance, my landlord owns a high-end Lexus. On the rare occasions that I've ridden with him, I appreciate the quality of design and manufacturing precision of his vehicle. However, I like my 12-year-old Saab SportWagon much more, for all sorts of idiosyncratic reasons.
An obvious example in the world of juices is that over the past months I've fallen out of love somewhat with many of Backwoods Brew's tobacco juices, but I still respect and admire Don's creativity and craftsmanship as an artisan juice-maker.
