While some clever folks have ferreted away a little Chief Hopper for the Season 2 premiere, the bottles you may have seen on social media are no longer available. They were a part of a special release in the spring that is not ongoing.
However, if you're in Michigan, you can throw yourself a little Stranger Things beer hootenanny, because Short's Brewing has made a total of three Stranger Things-themed beers available exclusively in the taproom. On top of Chief Hopper, there's Run, a sour stout "aged in a mix of Two James Rye Whiskey barrels and Madeira casks" then "fermented with dried orange and dried local cherry," a spokesperson tells Thrillist.
There's also "The Upside Down," which is an Imperial Experimental English Nut Brown Ale made with waffles and local syrup. It was also probably brewed in the presence of joyous high fives because the whole thing is wonderful.
