In the business world, there's rarely a thing as growing too big. But unfortunately for Sam Adams brewer Boston Beer (SAM), the price of success could be higher costs and the loss of its label as an "artisan" craft beer.

That's not to say a cold bottle of Sam Adams Summer Ale will taste any different to consumers. But according to the Brewers Association, "artisan" brewers include small outfits that put out less than two million barrels of suds a year. That means the brewer that almost single-handedly sparked interest in smaller batch brews with more flavor could be pushed into the same category as the big beer vendors like Anheuser Buch Inbev (BUD) and Molson Coors (TAP).

In a very interesting interview from The Wall Street Journal with Jim Koch, chairman of Boston Beer (SAM), the entrepreneur was asked about the future of craft breweries.

For those who are not familiar with the story of Jim Koch, he was a consultant in Boston who decided to brew a new beer and sold it to Boston bars. The little brewer that could proved that there was a niche for a smaller beer, and Boston Beer is now a publicly traded company. In fact, as the article points out, Mr. Koch "has helped foster a revolution in small-batch American brewing."
