The World's best beer is obviously Courage Directors, strange how everyone else seems to have missed that. But there again Courage also make something they call "Best" which, also quite obviously, isn't.
Justification:
As we all know different times, situations, accompanying food can make different beers ideal for different situations. For this reason some may say "there cannot be a single best beer"
However, consider a sunny day, a cold light beer would be very nice indeed, but look they have Directors, the cellar is well kept and just the right coolness. The copper brew is not too thick nor malty, dare I say refreshing even, just the job.
Or consider a freezing winter night, the fires on in the corner, maybe a thick syrupy sweet warm ale is called for to bring some cheer, but look, they have directors. That warming coppery colour, those fruity hints but underlying sweetness, not too cold, just the job.
On no, I've broken my leg, I can't get down the pub or never make it back. Look! They've put Directors in cans, and it's not too fizzy either. Just the job for the housebound.
What about going abroad, the opportunity to try something of the local culture, but hey, look! They export Directors to America, the homesickness disappears as the coppery delightful perfect balance of Malt and Hops eases the nerves and steadies the fear. Just the job.
Yes, the universal beer! Pleasant taste, perfect nose, the way it starts to move into the thighs and feet to relax those tensions away, Gently following to the temples and easing the nerves. Never sickening, not too strong but strong enough, never weak. Hurrah!
