We have the Washington Brewers Guild, similar to to the others. There's also the Washington Beer Commission, which the state legislature authorized to promote Washington breweries. One of their efforts is Washington Beer Lovers, which is for consumers and gets you discounts and special benefits at festivals and such.
Considering the number of breweries in Mississippi (1?) compared to WA (~100) it's not a big surprise.
We have a similar organization as yours, the Washington Beer & Wine Wholesalers Association. They are definitely not always in alignment with the needs of the breweries.
