@theGreenManblog - Asking which are "the best beers [craft beer taprooms] carry" is akin to asking which are the best vegetables farmers markets carry.
Thanks for your beer blog post: http://blogs.vancouversun.com/2013/02/04/vancouvers-best-craft-beer-taprooms-where-are-they/
For farmers markets the answer lies in what's fresh, in-season and which crops were especially flavourful that season; it's quite similar with craft beer bars.
The best craft beer bars have a constantly evolving tap list, delighting and surprising their beer enthusiast customers with the latest creations of brewers near and far, be they interesting infusions, boozy barrel-aged blends, or simply a fresh take on a quintessential classic. The best beer bars also pay close attention to cleaning and maintenance of their tap lines, as well as the proper serving temperature and glassware. Most importantly, the best beer bars have knowledgeable and super friendly and welcoming bartenders who are excited about spreading the beer love around!
When I visit Vancouver, The Alibi Room is my home (thanks Nigel!) and I'm stoked to see more and more legit beer bars opening up like Bitter Tasting Room. The bartender serving us during my first visit was the epitome of craft beer bar awesomeness: he uses his superior knowledge about beer to spark excitement and promote exploration (not to "show off" or "one up" as is common in the world of beer-nerdery). Thanks Simon! Below: happy customers at Bitter Tasting Room in Vancouver, BC (27-Sep-2012)
Perhaps the question, "what's the best beer they carry" is best suited to beer bars with a focus on their bottle selection, especially if they cellar. But, for craft beer bars, the real question is, what's the best beer they're tapping now?
