I have been purchasing Green Mountain Breakfast Blend Decafe K-Cups for years. I love the flavor. Even though it is decaf, to me it tastes like "regular". It is still strong enough that I put creamer in it to mellow it down a bit.
I really like this as a light roast. It provides me with the perfect coffee flavor and not too much acidity. This is helpful for keeping any heartburn at bay. The taste of the coffee is good as well.
