I've got a small cellar that sits at 12-14C all year round.I have a Eutectic wine fridge for the cheaper wines and a compressor fridge for the good ones.
The Eutectic can only cool to a maximum of 12 degrees below ambient which is not much use in summer.
That puts the wine at 28 degrees
The other one right next to it sits happily on 12 degrees all year round.
That's Tassy for you!
Not that I'm a wine buff, or "mild alcoholic" as someone said to me once
