Ex Input:
Bottled like an energy drink, Switch, doesn't contain the things you'd find in other carbonated beverages. There's no sugar, no caffeine, no corn syrup, no preservatives or artificial colors.  Instead, what you get is a refreshing, all-natural, lightly carbonated tangerine-orange drink loaded with Vitamin C. Think of it as orange soda without all the things you don't want. Switch has just the right amount of carbonation to make the beverage refreshing without being filling.  It's a zippy beverage made with real tangerine, apple, and grape juices, and would make a refreshing beverage, lunch, dinner, or snack-time drink.  There was a slight aftertaste that I'm chalking up to either the can or the citrus, but it didn't get in the way of enjoying the drink.  Make the "switch" to Switch.

Ex Input:
My local Walmart and Target both have this, ground or whole bean, at a regular price of less than $9 per 12 oz. bag. It's WAY overpriced here.  It is an excellent coffee - I'm drinking it as I write this: an interesting hint of woody, creamy, citrusy taste that's dark but without the burnt aftertaste that comes with many dark roasts.

Ex Input:
This canned food has real chunks of chicken in it.  Dogs love it.  Looks and smells better than human-quality canned beef stew (like Dinty Moore).
