Maybe my tastebuds are different but I bought this at a local healthfood store and I'm not completely sold on it.  I tried it in my tea and it did leave me w/ an aftertaste...just like most sweetners. *shrugs*

Ex Input:
We have three large dogs - two malamutes and a husky mix. I'd read a few of the reviews on here that said that these treats were only good for large dogs, so I figured they'd be perfect for my three chow hounds. Unfortunately these are much smaller than I thought they were. Two, three bites tops and my dogs would have them down, and they didn't seem to like them as much as they like their regular bones (cheap, regular bones). So, nope, I don't think that these are that great, and apparently neither did my dogs.

I find that I have to use the seven ounce setting on my coffeemaker to brew this coffee, since it seems like a " weak brew " to us. I am going to try the extra bold for our next order.
