I can imagine it must be tough to ensure that there's enough of a variety of styles to appeal to the most potential customers, but I absolutely agree that you can really only get the best out of yourself if you have a passion for what you're producing. I think the breweries in bigger markets and/or that have established themselves as being the top at what they do (I'm thinking of places like Other Half, Monkish, Trillium, Jester King, Bottle Logic, etc.) have an upper hand in that they have established a large and loyal following who will remain loyal as long as they continue to pump out high-quality beverages. For a place like yours - out in a "less accessible" setting and needing to appeal to locals and tourists - it must be a difficult balancing act on producing beers *you* like while also pumping out product that maybe isn't something you'd necessarily choose to drink yourself.
That's awesome that you've branched out into other types of beers, especially the Belgians. I'm not hugely into them, to be honest, but I can certainly appreciate them. Now...as for barrel aging, I'm all freakin' in. I *love* a big barrel-aged stout (and to a lesser extent, barleywine), so I really like hearing that you're going to give them a shot.
I have a big stout in my brew plan - probably brew it in December - that will be aged on bourbon-soaked oak spirals, cocoa nibs, and vanilla beans (might toss in a little cinnamon, too). Can't wait to get that going so I can let it keg condition until next fall.
