Anheuser-Busch InBev (BUD) has launched a new website that lets customers find out exactly where their Budweiser came from -- including where it was bottled and even the farms that grew the hops and barley.

A gimmick? Yes. But it's one that the company hopes will resonate with consumers and perhaps even revive the slumping sales of Budweiser.

The "Track Your Bud" site and smartphone app asks users to enter the "born on" date located on bottles and cans of beer. Smartphone users can also scan the QR code on a Budweiser.

The program will then show which brewery made the beer. Budweiser has 12 breweries in the U.S., including its flagship location in St. Louis.

It will also tell consumers where the raw materials came from. Budweiser uses barley farms in Idaho, Montana and North Dakota and hop farms in Washington, Oregon and Germany, Packaging Digest reports. Budweiser is adding a social media element as well, letting users collect badges from each U.S. brewery and even name certain batches of beer.

"Budweiser has a great story, and we want to tell it in a new way that demonstrates the pride, passion and craftsmanship at our breweries that's been the backbone of Budweiser for generations," executive Rob McCarthy said, according to Packaging Digest.

The move is part of a larger initiative at Anheuser-Busch to spark interest in Budweiser after prolonged sales declines. Bud Light is still the No. 1 beer in America, but Coors Light recently booted Budweiser from the No. 2 spot.

Budweiser has seen sales drop for years, and ran into serious trouble in 2009 and 2010. Last year wasn't as bad, but shipments still fell 4.6%, according to trade publication Beer Marketer's Insights. Coors Light shipments rose less than 1%, but that was enough to move it into second place.

Anheuser-Busch is desperate to revive Budweiser, trying everything from dressing up its cans with bow ties to telling drinkers to "Grab some buds" in new music-heavy commercials. The company even handed out free samples of Budweiser at trendy bars and restaurants.

The company also recently unveiled the low-calorie Bud Light Platinum, which has a higher alcohol content than the average American brew. The following video has more details on the newest member of the Budweiser family.
