Disappointing third-quarter results released Thursday evening confirmed that Boston Beer, the $2 billion owner of Sam Adams and Angry Orchard and one of the country's largest independent craft brewers, is falling flat. Revenue plunged by a record 13.5 percent as shipments declined, and the company had to lower its earnings guidance for the year to $6.30 to $6.70 a share, down from a previous estimate of $6.40 to $7. Its shares tumbled more than 6 percent when the market opened Friday morning.
