So cold that frozen beer likely for fans at Green Bay

At Lambeau Field on Sunday, there may be Frozen Beer in addition to the Frozen Tundra.

Temperatures for the 49ers-Packers playoff game are expected to range from a glacial minus-5 degrees to minus-20 degrees, according to weather.com. So, for those tailgating in Green Bay or buying beers from Lambeau concession vendors, how long will it take for a Coors Light to turn into a Coors Slushy?

According to Cornell professor H. Floyd Davis, it should be under an hour.

Davis was gracious enough to turn The Post’s question into an experiment. He poured a refrigerated 12-ounce Labatts Blue into a plastic cup, setting the cup outside his Lansing, N.Y., home, where the temperature was zero degrees with barely any wind.

Davis said 40 minutes into the experiment, the beer developed approximately a 2-inch deep crust that would have made drinking the Labatts a challenge.

“After an hour, I tried to pour it out into a measuring cup,” Davis said.” Only about four ounces of the beer was liquid, the remaining eight ounces had the consistency of a ‘slushy.’ ”

“Of course, this was at zero degrees [Fahrenheit] with no wind. At -20 [Fahrenheit], and some wind, my guess is that you should [get] half the times given above.”

Will Dichtel, an assistant professor at Cornell, said he thinks there’s a better avenue to go on Sunday than beer.

“I can’t imagine it being very fun to drink beer outside on a minus-15 degree day — coffee with whiskey sounds like a much better option,” he said.

And Cornell professor Steven Ealick said he believes the question of when a beer would freeze at Lambeau is moot.

“It would be impossible for a 16-ounce beer to freeze at a Green Bay Packers game,” he said, “because it would be consumed before it reaches a suitably low temperature.”
