This tea was supposed to be loose tea.  I purchase loose tea all the time.  Instead of packaging the tea in bags, they left it loose.  Gave a very couldy tea with a bitter taste.

Due to health issues, my husband is newly required to eat a gluten free diet. He acted as if he was on death row. Finding this product has help immensely. I can make him pancakes with fresh fruit and he doesn't feel he is being unfairly punished. Also, my neighbor was faced with a similar circumstance. I shared one of the boxes with her and she is now a fan! <a href="http://www.amazon.com/gp/product/B004391DK0">Bisquick Pancake and Baking Mix, Gluten-Free, 16-Ounce Boxes (Pack of 3)</a>

We have been experimenting with different brands of K-Cups since we purchased our Keurig last Christmas.  While this one was okay, it just is not as good Green Mountain's Breakfast Blend for an everyday staple.  We haven't tried Green Mountain Columbian yet as a closer comparison.  However, when we make a larger cup of coffee with this one, the brew is noticibly weaker than with GM Breakfast Blend.  Also, please note that we LOVE Timothy's World Italian Blend!!  It is definitely amount our favorites.
