When I was talking with my Starbucks folks about the new SF gingerbread latters, I happened to ask about the eggnog ones. They said that they used real eggnog in the carton for those and pulled out the carton of eggnog to show me. We all read the nutrition label and it was the real, full sugar, full fat stuff that is a black hole of calories -- something like 340 calories in a cup.
Eggnog lattes aren't listed on the Starbucks website yet, but the calories would have to be through the roof! Guess I'll be skipping those this year.
