I can taste the difference ... decaf tastes vaguely like metal. Honestly, I wish I could quit the coffee habit because I know it's not healthy, but it tastes so darned good!
I hear mixed messages about the healthiness or non-healthiness of coffee. For me, I think the unhealthy part is the addition of the sweetened creamers - I am absolutely crazy about them!!
I also drink an herbal coffee called Teeccino
. In fact, I drink more Teeccino than regular coffee. And it's SOOOOO delicious. And it's even dark, and robust, and makes the kitchen smell delicious when it's brewed.
I do love the taste of coffee - but I love Teeccino too, and it's a nice healthy alternative (except when I add in all that sweet creamer LOL).
