Looking for a certain beer?

I recently tried a seasonal beer from Spoetzl Brewery called Shiner Dortmunder. You may be familiar with Shiner Bock I see it almost everywhere. The Dortmunder was the beer ive been searching for but it's out of season now and they no longer distribute it. I don't know how to describe it so can any of you beer connoisseurs out there refer me to a beer similar to that one? It was a spring ale so I'm not looking for another seasonal beer that I can't find anymore, I'm looking for one I can drink year round. I'm a fan of yuengling lager, killians Irish red, amber bock, and other amber colored beers but the Dortmunder was was lighter amber in color but taste like a fresh spring dark beer.
