What size coffee are you drinking?

Coffee lovers are living in a culture of not only fancy lattes but - increasingly - supersized cups. For the next month, Tim Hortons is discontinuing its small 8-ounce cup in two Canadian markets as part of a test-run.

They're calling the 10-ounce cup "small" from now on, and all the size names are moving up a notch...up to 24 ounces. Earlier this year, Starbucks announced its new "Trenta" size...which is more than an average bottle of wine!

For more on the popularity of the caffeinated brew, we reached Morton Satin. He's the author of "Coffee Talk: The Stimulating Story of the World's Most Popular Brew."
