I've just read my first KAF blog ... it's fantastic (and fun). Last week I filled out a KAF survey, and I marked that I didn't know you had a blog - how dumb. I always see that blog line on your front page, and know you have a blog - but I had never looked at it until today. Sorry. I clicked the wrong circle ... no big deal, I know. You have a marvelous company - one of the best. Thanks for all the inspiration to bake - and create - and bring joy to others in this way! PS I have Butter Rum & Buttery Sweet Dough & Eggnog & Natural Raspberry flavorings that are a year or MORE old ... how long are they okay to use??? With all the alcohol, they may be well-preserved??? Thanks. (Also, I bake in Colorado Springs at an altitude of 7000 ft ... which affects some baking - not cookies. It would be very helpful to have that concern addressed by your experts sometime.) Joan, so glad you discovered our blog via the survey! Welcome. The flavors/extracts are fine; they don't go bad. And as for altitude - take a look at our Guide to High-Altitude Baking. Come visit again! PJH
