Just went to tap one of my lagers and found it frozen! Not sure how or why as the other kegs are fine and this is the first time it has happened. I’m letting it defrost at 64F. Is it toast?
Dave
No…I had a keg of Kolsch freeze solid a few years ago and it turned out to be a very good beer. It never really cleared but tasted great. No worries there.
Thanks Ron. My plan is to leave it at 64F until it completely defrosts and then tap it and bring it down to 40F for serving. Sound good to you?
Dave
Sounds like a good plan to me.
sounds like that one keg was to near the cold air input. I have heard people have good success with a little computer fan in the fridge to move the cold around a bit more.
Absolutely not. It’s slush. 
Mort, Sounds like exactly what I need. Is it battery or direct wired?
And this morning, not only were my two new lagers bubbling away, but the keg was defrosted and tapped (and pretty tasty! ;D). Will know more when I get back from the shore and have a proper tasting.
Dave
Maybe euge willchime in with details, I think I remember him saying that he had that set up. I would think battery power would be cool, no wires, but they would conk out fast in the cold.
I repurposed a carboy shield in my serving fridge and that did the trick. Just bent it into a V shape where the cold air comes in. So it sits in between the two rear kegs. Works like a champ.
The one frozen keg I had, never returned to what it originally tasted like. It was an IPA, was super cloudy and the taste was not great.
Cut the top off, stick a piece of rebar in there, and take your giant beersicle to a party.
NICE!
I put it back in the fridge after defrosting, let it settle for 2 days and poured my first last night after a long business trip to Atlanta. Not sure if it was the long day but it tasted pretty darn good! Crystal clear too! Go figure…in fact, I think I’ll try it again now!
Dave
Perhaps a way to make an Eisbock?
I wired up an old phone charger to a case fan. Works well and the cord is slim enough not to mess with the seal.
Anyway make sure you thaw the keg completely. You may be fooled if it starts to produce beer. My experience was that I got a nice bourbon for about 4 pints and when it actually finished thawing I had Schlitz left over to drink. :o
Happens to me all the time, just thaw it out and your good
