The beer is in the freezer.

And, as long as it stays there, there will be beer in the fridge.

Great Western Brewing Company is collaborating with the Saskatchewan Institute of Applied Science and Technology (SIAST) to preserve the yeast strain essential to making the Saskatoon company's beers.

"SIAST has the expertise, equipment and technology to identify the yeast's genotype," said Anita Fuller with Great Western.

"This baseline information is critical to recovering the yeast if it were damaged or contaminated in a crisis, such as a fire or flood."

Once the company's strain is identified, a yeast sample will be frozen and stored off-site.
