This is the best Hot Cocoa product I have found for the Keurig K-cup Brewer. The others I have tried do not have the test or alot of the product remains in the cup.

I tested this one on my twin 10-month old babies and they liked it immediately. It was their first beef and their first spinach. I had already given them chicken and they really like it so they are not vegetarians yet anyway. Mostly I wanted this product for the spinach and the higher iron content. Somehow they made this particular flavor brand tasty for babies. I like getting these by the case rather than buying them a jar at a time at the store since 2 babies eat so much. It's good to keep several flavor brands around too I think, to give your baby a variety. I'm sure I'll get another case when this one is finished. Ingredients per the label: Water, Organic Carrots, Organic Finely Ground Beef, Organic Spinach, Organic Garbanzo Bean Flour, Organic Tomato Paste, Organic Whole Durum Wheat Flour. CONTAINS: WHEAT. This has 110 calories, 31% protein, 100% vitamin A, 8% vitamin C, 4% calcium and 4% iron. I've been informed that the percentage of daily needs met is based on an adult.

The 500 Mile Chai is just wonderful - the right balance of mellowness and spiciness. I've tried some chai's that are a bit too spicy, but this one is very well balanced. Great with almond milk and bonus points for it being organic (in as much as one can trust the "organic" label...). Compare to Peet's chai, I like the 500 mile better, as IMO Peet's is a little too much on the spicy side (although I do still like Peet's and some may prefer that flavor profile).
