A drought in Brazil is set to send coffee prices through the roof.  Brazil supplies about a third of the world's coffee, and analysts say coffee prices in grocery stores could rise as much as 25 percent by next month.

Wholesale coffee prices area already at a two-year high.

Big chains like Starbucks lock in prices with their bean suppliers well in advance, so java drinkers who get their jolt at the local coffee shop may not feel the pinch for a while.
