Packaged to look like bottled water, Smirnoff Source tastes like vodka with a hint of citrus, but is actually a malt beverage. It is being marketed as an alternative to light beers; it is lighter in taste, calories, carbonation, and alcohol. It's also lighter than other malt beverages on the market weighing in at a whopping 3.5% alcohol content. The only thing that's not light about source is its pricetag. Four packs are being sold for about $10.
