This Melitta Riviera Sunset blend is a nice, and light coffee that is suitable for anytime of day.  It's particularly great for drinking at night because it is decaffeinated.  The texture is nice, and does not have an acidic taste or anything.  It's meant for casual drinkers.  I do prefer my coffee darker, WITH caffine, but I did enjoy this blend.  I would recommend giving this a try and judge for yourself.

THis product (which i am not allowed to return) has ingrediants of salt, spices, hydrolysed soy protein, that last item is the common industry con for adding msg to your food. Every soup on your grocers shelf contains msg, but, i digress. So, the third ingrediant is a form of MSG, further down the ingrediant list is proudly displayed ... Monosodium Gludamate, ...MSG. This does not add spice to your food, it stimulats your tongue into feeling that the food tastes good, when IT DOES NOT. MSG can make dogfood taste like hamburger. anyone who thinks this is making their food taste cajun may be serving ALPO.  Tones and Durkee (sp) do not contain MSG, I prefer Tones!  I have 8 eight ounce cans of this stuff.. would anybody like to buy some hamburger from me?

This stuff tastes awesome! And for once in a kiwi/berry drink you can taste the kiwi, I'd be very hard pressed to tell the difference between this and a traditional soda.  I also like the fact that it's in a tall and slender can, fits in the fridge better and you can't mistake it for that pesky regular soda... :)  However I would not say that this would be a better alternative to soda based on the fact that it still has a solid 33g of sugar. Yes it is better for you because it is made with 100% real juice instead of corn syrup, which I definitely like, but it's no different then drinking the 100% frozen juice from concentrate.  Overall I really like the product and will probably buy some to have as an alternative to soda (for those few times a year).  Pros: You can actually taste the kiwi and the berries. 100% REAL juice, no artificial flavoring. Very carbonated, not the least bit flat. Quenches your thirst and is refreshing. NO CORN SYRUP!!!  Cons: Spendy. Although it is all natural, still contains 33g of sugar... 135 calories a can (ouch!).
