Boston Beer shares rose on news of the Dogfish Head acquisition. The brewer of Samuel Adams has seen declining sales of its beer brands. The losses have been offset by rising sales for its Angry Orchard ciders and hard seltzer products.

In May, the price of Boston Beer stock rose on news of the Dogfish merger. Dogfish Head has not resorted to deep discounting of its beer and is believed to be solidly profitable. Dogfish Head may also benefit from the distribution system of Boston Beer.

Sam Calagione has long touted the independence of Dogfish Head, but also cited the difficulties of being caught in between brewing giants and a growing number of hyperlocal brewers. Delaware alone has a couple of dozen breweries.

In addition, mega brewers have been acquiring craft operations like Chicago’s Goose Island.
