Ex Input:
So when you purchase beans of a reputable brand you would expect to get fresh beans. They tasted old from the opening of the bag and so even if the date was well in advance of it's expiration I can only surmise that quality control was an issue in the storage or shipping of the beans. But I won't be ordering any more espresso beans from this company unless they can correct this.

Ex Output:
Negative


Ex Input:
I have tried various brands of stevia, but I always come back to NuNaturals.  I buy the 12 ounce container because I use it to sweeten everything.  If you have a sweet tooth as I do but don't need the added pounds, then this is the ticket for you.  I drink a lot of tea, and this is my sweetener.  A lot of other stevia brands leave a bitter after taste, but this is the best that I have found to resolve that problem.  Highly recommended.

Ex Output:
Positive


Ex Input:
The pancakes taste great without any recipe adjustments for my son's egg allergy.  It's also great for camping or any time you'd like to be able to make pancakes without having fresh eggs available.

Ex Output:

Positive
