Soon as I got this bag of decaf I made a big mug and it filled my house with the wonderful aroma of high quality fresh brewed coffee.  It is very finely ground but I still used the same amount I normally do and it turned out great.  I added some soy milk, sat back, and enjoyed my rare treat of an after-noon coffee break!!!  Definitely will buy some of this for the winter months so I can treat myself to excellent hot coffee any time of the day or night!

The wheat free brownie mix is not to my liking.  I won't be reordering. I'd rather not eat chocolate than to eat these brownies.

Not paying attention, I thought this product was simply vanilla extract when I purchased it, tried it in my coffee, and got a shock. Yummy!  I had to go examine the bottle, and realized my yummy mistake.  I wonder what glycerin is, what it's made of...? is it a fat? At any rate, it is delicious!
