I use them--in beer--mainly so I know what the brewer was trying to do. Or at least I can narrow the range some.Fair enough. But... beware taxonomists.
Like, with wine - all the language around wine flavors and characteristics beyond the most basic can be demonstrated to be, well, hogwash. In a blind test, a given taster will often attribute highly different characteristics to the same wine on different tastings.
Taxonomies based on such, then, are not of practical value, as they are not dependable.
