I really liked Wolfgang Pucks Hawaiian Hazelnut. It was my favorite, except has been discontinued. The Eight-O'Clock Hazelnut is a great substitute I just wish it didn't have a slight aftertaste.
Pros: Pleasing Aroma, Smooth Taste, Not Bitter, Pleasing Roast
I usually only drink "black" coffee in the mornings.... but was out to dinner and had a cup of coffee with a shot of Bailey's Hazelnut Irish Cream. It was so good I decided I'd order Hazelnut flavored coffee. Been a drinker of 8'OClock coffee for 45 years so I know they always had quality coffees. So I ordered a carton and wasn't disappointed. I discovered grocers sell a non alcoholic Bailey's Irish Cream Creamer in the dairy aisle. A cup of this coffee with a splash of the creamer has now become my evening ritual. Sometimes I even add a touch of the "real" Baileys topped off with some whipped cream. Give it a try and you'll be hooked too.
