My experience with this approach is that it's a pretty slow way to cool wort. Air and snow are great insulators. I guess it's a little faster than no-chill.

I agree. Outside, but not in the snow, will be faster, because of the air circulation. Snow is a great isolation. You know Igloos? Here in Québec, they build a Ice Hotel (yhea, hotel made of ice), and you can sleep easily there, no heating, only natural insolation of the ice and snow.

You did see that it is/was 12F for the ambient air temp. You want a bit of insulation when it is that cold. A little faster than no chill? Seriously?

Yeah, I found that out the hard way. After fifteen minutes and the lid still scorching hot I made a snow bath in the kitchen sink. I think the whole cooling process took over 30mins. I hope I didn't mess up my beer.

Yes, when I learned my lesson on this it was 10F outside. It took me 45 minutes to get from 212 to 140 F.

Certainly didn't ruin my beer though. I don't think you have anything to worry about there. I think the whole DMS concern with slow chilling is overstated. There's plenty of no chill brewers on here that seem to get good results.

The main problem with a long chilling, is the extended time that the wort is exposed to contamination. With a lid on, it should not be a problem. But that said, a lid will extent the chilling time...

It works well if you keep the wort churning, the lid off, and keep moving it to melt fresh snow. The pot gets ICE cold and it acts like a plate chiller of sorts. But letting it sit in place after it has melted the snow won't do much.

I tried this last winter, was painfully slow to reach pitching temp.

Heh, was going to say if it's that cold out then a standard immersion chiller would have that cooled in probably under ten minutes. When it's that cold out here in NJ over the winter I cool my beer to pitching temp in 8-11 minutes since the ground water is so cold.
