War for grounds: Coffee firms Peet's and Green Mountain sweeten Diedrich bids


There's a bidding war brewing over Diedrich Coffee (DDRX), the maker of single-serving cups of joe for home or office percolation.

Diedrich agreed on Nov. 2 to sell itself to Peet's Coffee and Tea (PEET), the java chain that is said to have inspired Starbucks (SBUX). But now Peet's has competition from Green Mountain Coffee Roasters (GMCR), owner of Keurig, the maker of the machine that brews Diedrich's cups.
