The 5/5 appearance joke has pretty much run its course but I want to get the last of it out of you all.
Forget about how good a beer smells or tastes for a moment. What beer deserves 5/5 for appearance and why? It can be anything, or a combination of things... A great bottle or tap badge (or iPod), a raunchy label, it pours perfectly, it has a head that stands up out of the glass and never fades... Post some pics and wax lyrical.
Praise or condemn the beer if you must but all I really want to hear is what looks hot (and, because we can't ale-ways be positive, what looks like rot).
