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 Output:
5

Ex Input:
I've read the reviews and I agree that Yuban is absolutely the best coffee but at $100 for 12 cans comes to over $8 a can. That's $3 more a can than I pay at my local store. I don't understand the high price?

Ex Input:
The smell at first was just like a bed of fresh roses. Even though the rose content is very minimal I found the smell overwhelming. I did not like that this brand of spices does not have a seal in place and only a loosely screwed on lid. There is no shaker lid either. You open it and it dumps. I am questioning how only a few minute pieces of roses could produce such a perfume odor. I hope it is not chemically enhanced. With the lid being loose and not sealed I have doubts about the safety of the product.
