As I am interested in opinions on my situation, but it is OT for the "Vintec wine cellar offer", I have moved the quote here.
The lower the temp the harder you make the fridge work to maintain that temp.
There is no need to have it too cold.
I keep my reds at 15 and my whites/champagne at 12.
I hear the compressor in my fridges come on about once a day only.
I agree that that the lower a cooling device is set, the harder it will work. I also know that how hard and individual unit works will also be affected by many other things, it is not limited to just the temperature setting. Some I can think of include; how full / empty it is, how much airflow / space is around it, the geographic location, and if it is located in a conditioned environment or not. I am sure there are other variables, and that some would make more difference then others.
Due to where I live, I set mine on 11 but am thinking of lowering it to 10. The Vintec's I have are cooling only, so over winter there is a long period where mine do not kick in at all.
Is 11 too low? maybe? but at least the wine only varies in temp around 2 - 2.5 deg over a year, if I set mine on 15 deg it would vary 7 - 7.5 deg. From everything I read, temperature fluctuations are more detrimental.
Curious to hear others thoughts on storing wine at less than 12 deg.
