Good question! It's set me thinking.
I think one of the best things to do is drink a lot of other people's beer. I know; grand idea, innit?
But I'm serious. If you've got a local homebrewing club, join it. Start hitting meetings and hanging out with the veterans. Every single club meeting I've ever attended, anywhere, there has been a sampling session. If you find a recipe you think is a divine example of a style, as the brewer how she formulated the recipe and why she made the decisions she did during the formulation and brewing process.
Rarely, you'll get, "Well, I had a bit of this and a bit of that and I threw it all together to see what would happen." While cool as hell, that's not quite
what you're looking for, is it? You're looking for the in-depth thoughtfulness that produces that balance which is so difficult to define, much less achieve.
In other words, choose a master carefully, young Paduan.
IMO, the best road to your goal lies in the traditional master/apprentice relationship. The cool part is you get to have an ultra-cool friend who shares beer with you.
