Example Input: Brew style: french press, espresso Smell: Nothing special here, decent 'coffee' smell with some earthiness.  No caramel notes, no sweetness. Taste: Mild, earthy, somewhat smokey, dirty mouth feel, finish is short.  I mostly brew with a french press but i tried it in my espresso maker just to see how it would fair.  The caffeine seemed very pronounced to me, there was no sweetness to speak of.  It did have a very nice crema though. Overall: I wont be buying this again, its nothing special.

Example Input: ...........but still not that great. It's bland. Even when I added salt, pepper, milk, and butter, it didn't taste like the best I've had. But at least it's edible, unlike every other canned clam chowder out there. If I can find a way to make this taste better than I'd love it. It's the best CANNED clam chowder I've ever had, but it's not that great. The clams taste good.  EDIT: I had a 2nd can and I made it today, I added only a little bit of milk and I added NO salt, pepper, or butter, and it actually tastes a lot better than when I did. So I suggest adding nothing but some milk or cream to this soup. It's still not the best I've ever had though.

Example Input: They're perfect training treats for my dogs.  They go to the place where they're stored and stand there until I get a handful for our play games.
