So I drink a lot of beer (go figure) and I try to characterize it each time. How much carbonation there is, what color it is, mouth feel, what specific flavors are involved, how hoppy it is, how malty it is, and many other things. Many of these things correspond to things that can be measured numerically or are at least partially determined by commonly measured things (like how mouth feel and specific gravity are related but not the same)
Currently I don't brew beer but am looking to get into it. I plan on measuring all these values as I brew. However that doesn't give me much of feel for the numbers until I have a good few brews, involving many variations of these values, under my belt.
What would be nice is if I could get some reference that could explain these properties for various beers. For instance IBUs of different beers are mentioned quite a bit and now I have a vague feel for how hoppy a beer will be based on the IBU rating (though, IBUs seem a bit inconsistent to me). I don't however have a feel for measurements of things like specific gravity, color, clarity, foaminess, and other things.
