Love this hot chocolate--nice creamy flavor.  The price is good and I love the single packs.  This is not a flavor available to me locally.

Ex Output:
5


Ex Input:
I love this coffee. I do wish it came already ground as I don't have a grinder and use a blender instead. But it's worth it. Many flavored coffees I've tried only seem to have a flavored odor that doesn't reach the coffee, but this one manages both.

Ex Input:
The flavor of the old Beer Nuts is almost entirely gone. The Beer Nuts are now just plain Spanish Peanuts with a slight flavor, hardly noticeable. Extremely disappointing.
