Can you lager outdoors, in the Winter as long as you keep the beer out of the light? I don't have the means or the containers needed to Lager.
I've got a shed behind my house which I call "the lagering shed". You should know the range of temperatures which are likely to occur, and keep an eye on your beer. I live in south-western British Colombia, where winter temperatures are great for outdoor lagering. We sometimes go a bit below zero, but usually not much below, and usually not for long.
Once I allowed my beer to partly freeze. Part of the contents of the carboy were in a slush or slurpee form. As I recall, I brought it in at that point. Of course you will want to avoid your beer freezing further than this.
