It's dropping into the mid-teens tonight. My kegs are in the fridge, in the uninsulated garage. Need to worry?

I would not worry. Your fridge is insulated which will protect it from the cold. I am facing the same issue tonight too. It is currently 28 outside. The garage is 44 and the fridge is 38, which is what the controller is set for.

It depends on the alcohol strength and I'm sure with a little searching you can find a chart online that will tell you at what temp it will freeze. It is quite a bit below the freezing temp of water, plus you have the insulation of the fridge as mentioned. What you should be most concerned with is the lines. If there is beer in the lines that little bit of liquid can freeze easier than a full keg and when it contracts and expands you can lose a lot of beer through clamps and such.

We once left a full 15.5 gallon keg outside in the mountains in June and the lines froze. By the next morning, about 15 gallons of beer ended up in the trash can holding the keg. It's not a pleasant site seeing grown men (and women) crying.

I've had temps down in the teens and below with no problems yet. My garage is also uninsulated. As far as beer lines go, cobra taps on the inside of the fridge never froze either. Now that I'm using faucets through the door, I'll just try to keep them running enough so I don't take a chance.

I seem to remember it's somewhere around 28F or so. I got that from some website a while back, so YMMV.

If your garage is attached to your house, and your beer is in an insulated frig, you'll probably be ok. It takes a lot to heat or cool water. If you have multiple kegs in your frig, they'll effectively insulate each other. Now the lines may be another story...

I've had beer freeze in a keg in my lagering fridge that was set to 32. The 2 kegs in the front were fine but the one in the back next to where the freezer vent was froze some. It had probably less than a gal in it at the time and had been in there a while too.

Overnight temperatures dropped to -4d here.

So I have just learned here, that at 24d inside the garage temperature, it will freeze a Munich Dunkel (OG 1.063). My Baltic Porter (OG 1.080)is OK. Both were in 5 gallon cornies.

I also have a case of bottles of the Baltic porter, and a 6 pack of Goose Island IPA sitting out in the same space. Both are OK.

My fridge out in the garage has never froze any of my bottled beer so it must be well enough insulated.

Doesn't freezing also have something to do with altitude??? I mean, I have bottles out in my garage now sitting at around 25F and they are not frozen. Very cold, but not frozen. But, when were recently in Colorado in the mountains we noticed a sixer of beer that someone threw away that had been sitting in thier trunk overnight and had frozen.

I don't know how to explain the science behind this, but it makes sense to me.

Yes altitude has something to do with it, and I think that beer in a "cornie" or cans, will freeze a bit faster than beer in bottles.

I have kept some beer in bottles at very cold temperatures. I have also noticed that some bottled beer when very cold will blow off immediately after opening. A real gusher. I have left bottles and cans of diet coke out in the car and they have split and exploded.

The thing that I would like to know though is can you leave a keg or bottles of you precious home brew out in the extreme cold (lagering), "drifting from thaw to freeze" and will it still be OK?

In other words did those Alpine caves ever get the beer below it's freezing point?

Early in my homebrewing days I was lagering an extract bock in a fridge in an unheated garage. There was an extreme cold snap, and after the third night of subzero F temperatures the beer froze, or at least had about a six-inch crust of ice on top with the rest slushy.

I was distraught and thought it might be ruined. I brought the carboy into the basement and hoped for the best. It had been lagering for about six weeks, so I thought the best course of action might be to bottle. After 24 hours I pitched some dry yeast, just in case, along with the priming solution.

To my surprise at the time, the beer turned out great. It was very clear and quite malty.
