Ex Input:
Was looking forward to this drink but was put off by its sweet soda-like taste.  Maybe it's an acquired taste? I'm not sure  but the high calories don't make me want to try.  Looking forward to a diet version.

I made cheddar biscuits with this and they came out a little dry the first time, but i adjusted the recipe and they were amazing. I just added a little more milk and another egg. (we have chickens that lay very small eggs, so 3 of our eggs is like 2 large store bought ones.)

I am a coffee fan who drinks my coffee black; nothing is added to alter the flavor of the coffee. As a result of this habit I find myself somewhat more critical of how a coffee tastes. As a general rule I prefer an Arabica bean but I could not find a reference to bean type on the bag. Curious I checked their web site and found they use the Arabica bean exclusively.  On the front of the bag there is reference to the process used to decaffeinate the Rivera Sunset coffee; the Swiss water process is used. Their web site provides a detailed explanation of this process which involves the removal of water soluble caffeine: "Unroasted coffee beans are immersed in heated water for several hours to remove the water-soluble caffeine present in the beans, as well as those coffee components that easily dissolve in water. The water is then drained from the beans and filtered or processed to remove the caffeine from the water. This decaffeinated water is then reintroduced to the coffee beans, allowing the flavor and aroma components to be absorbed by the coffee. Finally, the coffee is dried and ready for roasting."  More information is provided on the web site concerning the bean growing and selection process; I found the web site to be user friendly and well thought out.  Another habit of mine is the use of distilled water to brew coffee; I've found that public water supplies can provide water with a multitude of different tastes which can negatively influence the flavor of the coffee.  Let me finally mention the flavor of the coffee itself. First it is very smooth and rich; I almost never have more than one cup of coffee at a time but found myself thinking more would be nice. That is very rare! The coffee had a delicate fruity flavor which I found pleasing.  I did face one challenge with this coffee; the bag was very difficult to open without tearing it. After working on it for several minutes, I had decided I was not going to let a bag beat me, I discovered that I was able to open it be starting at the end where the bag was folded back. Once I got my finger inside the bag the rest came comparatively easy. Fortunately the two small tears I made in the bag were high enough to fold under when the bag was closed. The bag recommends storage in a refrigerator.  This coffee is pleasant and refreshing and I have enjoyed drinking it; if you are a coffee lover you owe it to yourself to give this coffee a try and see what you think. I hope you're as pleased with it as I am!
