BeerText is an SMS interface to BreweryDB.com. To use the service simply text the name of the beer in question to 315-679-4711. Within a few seconds you'll receive a series of messages back with information about the beer.
As a test I chose a few beers that are not nationally distributed. First up was "Port City Optimal Wit" which returned a three part text with the brewery's description. A test with "Blue & Gray Stonewall Stout" returned no results, just a tip to add the beer at brewerydb.com. Next I tried leaving off the brewery name and just sent "Gold Leaf Lager." That was still a successful hit, returning the information on this beer from Devils Backbone Brewing Company.
I expect I'll be making use of BeerText frequently. It's certainly quicker than loading a search engine. I've even made an entry in my address book to make it easier to enter the number.
