When a 125-year-old bottle of Alexander Keith’s IPA was found at the bottom of Halifax Harbor in Nova Scotia, there was only one thing to do: try it.

The beer was discovered in late November 2015 by amateur treasure hunter and scuba diver Jon Crouse. He told CTV Atlantic that he’d found it in three-meter-deep water; the bottle’s cork was still intact. While Crouse didn’t sample the beer, local bar owner Chris Reynolds and professor Andrew Macintosh, who specializes in fermentation research at Dalhousie University, did.

Macintosh said the beer shared similar characteristics with modern Keith’s, including a 4.3 on the pH scale. It also clocked in at 15 IBUs.

Reynolds enjoyed the sampling experience, saying the beer had acidic notes and hints of cherry and oak. Macintosh, however, didn’t have such kind words, noting the beer’s “odd meaty flavor” and “not altogether pleasant” smell.
