It's fallen down my priority of passions, but I still do enjoy the world of beer and it seems like it's been a while since the last great beer discussion. The coming of seasonal brews got me thinking of a bar debate I've had a couple times in the past that I enjoy. Say you setting up a home bar and you had to decide on your tap selections. Luckily, you get to pick from any beers in the world. Unluckily, once you make a pick, you can never change it. No rotating taps allowed. So how would you allocate your [fill in number] taps?
The gist is that you probably want to cover as much range as possible. So that leads to not only deciding, "what's my favorite [fill in type of beer]" but also "is this type different enough to be worth a permanent spot?"* Do I need a barley wine if I have a strong ale? Maybe my favorite porter is more on the chocolate side than the coffee side, but if my favorite stout is also more chocolately, then is there enough of a difference there? It becomes a game of maximizing flavor profiles and can lead (at least for me, I tend to relish these mental exercises too much) to interesting trade offs.
*You can apply this framework to about anything that involves a lot of repeated consumption. If you had to pick 5 dishes to eat for the rest of your life, etc.
Because I'm a beer geek, I ultimately went with ten as the number because something like five I feel is almost too constricting that it would stifle the trade offs and that's where I think the interesting discussion actually lies rather than "what's the best stout?" My ten, and subtopics in the comments.
