We’ve all been there. The beer is warm, and you want it cold. And fast. So, you pop it in the freezer for 20 minutes or so, pull it out, and enjoy something slightly cooler than what went in. No muss, no fuss. But there are the times when the beer is forgotten. That horror kicks in hours later or the next day, when the freezer is opened to reveal a burst container and a frozen, foamy mess. There’s a fine line when it comes to beer and freezing temperatures.
