Example Input: Newman products have been used in our home for years. After researching Newman's Adult Dog food I felt confident in giving the food to our two cocapoo's. They love it! One of them wolfs it down in 4 seconds! Really, I timed it. With so many companies recalling dog foods,I felt the Newman company being organic would be more reliable. Keeps me from worrying so much as I pour that bowl of food for them.
Example Output: 5

Example Input: I am very pleased with this selection.  I have not tried the other hot cocoa brands for Keurig but this one is awesome!  I bought the milk chocolate.

Example Input: ...or the good reviewers' taste buds are weak.  This is some disappointingly weak coffee.  I'm not some crazy "gotta have my jet black sludge to get through the day" coffee drinker - I'd say my favorite (and my wife's) is Caribou Blend.  This blend is WEAK, it can't hold half-and-half or even just whole milk without being wiped out.  Now, I will say I brew it on the "large cup" (9.25 oz, I believe) setting on our Keurig, so maybe it's a bit better on the 8oz setting, or even the small setting.  But Caribou (we also like Donut Shop, Green Mountain Kona Blend 10%, etc.) can be easily brewed on 9.25 and hold a good bold taste.  This coffee doesn't hold a CANDLE to any of those.  Now I'm stuck with 40+ of these. Blech...maybe the guests won't mind it! :)
