Fast food coffee upgrades

The Starbucks induced coffee craze being what it is, I'm surprised fast food restaurants didn't respond a long time ago, but the upgrade to better fast food coffee is fairly recent.

The most recent is Burger King with last week's introduction of BK Joe — brewed 100% from premium arabica beans. Sold in decaf, regular and "turbo strength" (extra caffeine), the coffee will be in all of Burger King's more than 7,000 U.S. stores by the end of November.

Other coffee upgrades:

• McDonald's tested a premium roast and plans a national rollout soon.
• Chick-fil-A added a Cafe Blends line this summer.
• Subway is trying gourmet java in some stores to lure morning traffic.
