Ship wreck 220 years ago in cold water saved on board beer

Off shore Tasmania the bottles of beer were found with their corks in tact.

Carefully studied the yeast was still viable and is being used to make beer to support a local museum.

The first difference between that beer and modern brews is that modern yeast is short lived. The yeast recovered from the bottles in the wreck quickly converts all the available sugar, but the yeast lives.

They're also making bread from recovered yeast.
