Mystery solved? 150-year-old alcohol found in Utah may not be beer after all

The artifact was found this summer at an archaeological site in Alta, Utah, a once-booming mining town now known for its ski resorts.

The bottle was brought to High West Distillery in Park City, the first legal distillery in Utah since the 1870s.

There, experts took a sip of the liquid within - and described the taste as unmistakably aged.

Isaac Winter, head of distilling at High West, said the liquid was "fruity."

"There's a little bit of leather," Winter said. "There's quite a bit of age on it."

While the experts were originally stumped at what the bottle contained, they now believe it held apple cider.

Speaking to FOX 13 this week, Winter described the lab results as "really exciting."

"We saw a couple of esters [organic compounds] that would suggest the base was apples," he said.

Winter and Lindley said the results, however, are not conclusive.

Additional sugar and acid tests are planned to confirm whether the liquid contains apple-specific compounds, like malic acid.

Winter even said the team would like to recreate the liquid as well, and that High West Distillery is "exploring different options to work with labs on plating this out."

Said Winter, "There's probably a whole mess of different microbes in there - bacteria, yeast."

"We need it to, you know, be able to eat sugar and create alcohol and CO2. We also want it to taste good at the end of the day."
