it's really difficult to remain relevant in the brewing industry. You can make the best beer on the planet but the consumer's "scramble for the latest and newest and weirdest" is what drives the styles that pop up on draft walls and store shelves. But all of that is tricky.
As far as cans goes, brewers are running out of names that aren't already taken or copyrighted, which is why there are so many cans out there, some of which don't have sensible names. And it is not easy to get new cans to market. You have to be sure that your distributor wants the beer (is you are forced to use a distro, which many are), to begin with, and that the retailer wants the beer. It also has to be approved by state authorities, which can take weeks or months. Printing the labels is expensive. the graphics are expensive. The cans are expensive.
My distributor want two styles (in cans) from the brewery I work at. They are not accepting any other styles at this time because they have to convince already crowded store shelves to take those beers. The beers they will take are a 'not bad" West Coast iPA and a bland Cream ale which started out as the brewery's flagship beers 7 years ago. There is a market for these beer. People want to drink these beer. These beers sell and a certain number of store shelves will take them. But there are a hundred other better beers i'd love to sell.
I imagine in states that allow for self distribution it is a lot easier to blanket different, weird and odd styles. I've never brewed in any of those states. I can brew anything I want for draft, so that is nice. But it's important to make sure it sells and that you can sell everything you make.
Egg Nog Beer aside, it's definitely a tricky business.
