Starbucks is launching a new push to remind consumers how much it knows about coffee. As competitors like Dunkin' Donuts, McDonald's and others increasingly take market share away from Starbucks it wants to play up the fact that coffee is more or less all it does and that it does it well. The company will be holding coffee tastings at their stores and producing a podcast online all playing up their expertise in the coffee market. This renewed emphasis on coffee comes after a series of brand extensions Starbucks has engaged in, including helping to promote the movie Akeelah and the Bee, which it also helped produce. Those extension efforts have, to some extent, caused some problems for the company as they've posted weak year-to-year sales increases, with some analysts saying they've lost their focus on selling coffee.
