Frozen lager

[kproudfoot]

I’ve been aging a lager for a few months in a temp controlled fridge with a brewers heating pad and ink bird temp controller. They have also been inside 2 5 gallon big mouth bubblers.

Well last weekend I brewed an ale and needed the fermentation fridge so I moved the lagers into another fridge and set the temp in the middle setting. I looked today and the 2 bubblers are frozen solid. But at the same time the 2 bottled beers that are in the same fridge and 2 packs of yeast are not. So my questions are

1) how is that possible. I pit kegs in the same fridge and they don’t freeze.
2) is my lager messed up?

Simple , the beer has alcohol in it lowering the freezing point . The yeast pack is the same as the yeast is grown in the pack if I’m not mistaken. Your beer will be fine !
