If this was called "Medium Roast", I would give it 4 stars. It's a good coffee. But this is called French Vanilla Caramel, and this review is based on the product's name. Let me say that vanilla and caramel are perhaps my favorite flavors... coffee, ice cream, candy, you name it... if it's vanilla or caramel, I love it. With the exception of this. Where's the vanilla? Where's the caramel? And don't get me wrong: I'm not trying to say that the flavors are too mild. I'm saying that they are NON-EXISTENT. And therefore, based on the name, this coffee gets 1 star.

I have ordered numerous teas, potions, lotions and other remedies...BUT have never had a lack of product in an order that was sealed. The tea bag wrapping in question was sealed without a tea bag inside. I would have said something sooner, however...I only tried these when I had a sinus infection and the last 3 times I tried to use one...the sealed pouch was EMPTY. BEWARE!

I have had real truffles only once that I can recall, and that very old memory is of a sublime taste. The slippery terminology used for 'truffle' oil gave me pause, but I decided to take a chance. To me, "infused" implies that something has been marinated in a liquid, not that a chemical has been simply mixed in. Sure enough, the ingredient list on the bottle is limited to olive oil and truffle "aroma." When I opened the bottle, I could only detect a garlic-like aroma, pleasant but not sublime. I first tried adding 1/4 teaspoon to a small serving of scrambled eggs, and could detect nothing. Today I made a 'two egg' (1/2 cup of eggbeaters) omelet flavored with tarragon and filled with simple sauteed potatos, scallions, and mushrooms. I drizzled on a full teaspoon of the 'truffle oil' after the omelet was set, immediately before filling and folding it. Again, I could discern no flavor or aroma other than the above ingredients. I rated this at 2 stars rather than one on the charitable assumption that a younger nose might detect some sort of aroma.
