In this video, Fool analyst Isaac Pino reviews three risks for Boston Beer (SAM +1.30%). First, the craft beer market is getting competitive with local brewers and seasonal brewers vying for consumers' attention. Given the "fashion" nature of craft brews, customer loyalty is spotty, as consumers like to experiment. Second, commodity prices could drive up costs for everything from hops to packaging. Lastly, the company is selling at 30 times earnings, but already holds 18% of the craft beer market. While this translates into 1% of the overall beer market, a big question is how they are going to grow, especially given the worrisome trend of increasing costs and declining revenues.
