title_body: Why do some brewing companies only export certain beers outside of their primary location?
upvoted_answer: I'd say it comes down to three things.
  
  Distribution Rights
  
  Breweries in most states are restricted by the three-tier system which divides the brewing industry into three categories:
  
  
  Producers
  Distributors
  Retailers.
  
  
  A few states allow the producer to engage in self-distribution (usually to a limited degree) but most require that a brewery get distribution rights with a third party, which will hold full, exclusive, and unlimited rights to shipping that producer's beer. ProBrewer.com has some excellent reading on the subject.
  
  
    The rules and regulations pertaining to the distribution and advertising of beer products are highly regulated and are enacted and enforced at the state level. Therefore, each state has its own set of laws in which the brewer is responsible for knowing and abiding by. It is incumbent on you, the brewer, to know the specific regulations of each state in which you sell.
  
  
  It boils down to what the distributor wants to do and state-by-state requirements for what can be sold there. Ohio has a cap on alcohol by volume of 12%. Any beer over 4% ABV in Oklahoma must be sold only at liquor stores at room temperature. It varies so much that some brewers don't want to go into those markets.
  
  Demand
  
  There's also the simple issue of supply and demand. In 2013, Founders Brewing delayed entering the Florida market for a few months while they brought on more 600BBL fermenters because of some slight under-reporting of potential market numbers. There's nothing worse than not being able to supply your customers with beer. (Ahem, Cigar City's Great Jai-Alai Shortage of 2013).
  
  Expense
  
  Bottling/canning beer is expensive. There's also only a certain amount of time available to package. This is why there will usually be only a certain number and type of beer that gets packaged in these containers until a brewery grows to a certain size that allows better economies of scale. Once there, it's easier to start releasing seasonals, one-offs, and more nuanced beer styles compared to just cranking out a wheat ale or amber ale.
