Ed. note: I am posting exerpts from the article to point out why all beer is not kosher.

"To answer your first question, yes, beer makers use actual oysters when brewing an oyster stout.

"When posed with the follow-up question of how, Joe Mashburn, head brewer at Night Shift, described the process of brewing Night’s Shift’s new Seamark Oyster Stout in further detail.

"'We first wash the oysters,” says Mashburn. “Then we proceed with brewing a stout as normal, with a lot of chocolate malt to get the color and flavor we’re chasing. Then, during the boil, the washed oysters are added directly to the kettle, where the heat causes them to open and release their brine.'

"The oysters, like all other solids, are removed during the brewing process, before the beer is allowed to ferment. In the case of Night Shift's new release, a portion of the beer was aged in a used bourbon barrel; after some time, the two portions of beer were blended back together."
