Example Input: these chips are good, and bad, and create moral dilemmas constantly. If wou are strong at will, or having a large BBQ go for it, but as for me, i was in the habit of bringing a new bag to work every three days, had to put in a lot of time on the treadmill to make up for it. BEWARE
Example Output: 4

Example Input: I'm dieting, and I use these as a "treat" to myself, when I'm craving chocolate.  I usually brew one of these & one of my coffee K-cups (either plain or hazelnut).  For 60 calories, it's not a bad way to satisfy a chocolate craving when you're on a "calorie-budget!"
Example Output: 3

Example Input: My bottle arrived just in time for a sushi dinner and game night planned with friends.  I had three soy sauces to choose from.  After some sampling we were all using the Bluegrass!  Everyone enjoyed the light smoothness a subtle sweetness.  We were splashing right on every piece, rather that dunking/dipping. Friends wanted to know where I found it. I'm going back to order more right now, and I'll be ordering 3 extra bottles because they are going to make a great little gift that's affordable and unique; instead of the traditional bottle of wine that so common it's boring.
