Once a bottle has been in the fridge, but not opened, is it OK to store again on shelf out of fridge?
Answer From Expert Roger Bohmrich MW
This is essentially the same question I answered recently, but it is clearly an ongoing concern. I suppose the general sense is that wine is highly fragile and will be harmed by moderate changes in temperature. In fact, few wines are that delicate, and the large majority probably endure rough handling crossing ocean or land, in warehouses, or in delivery vans en route to stores and restaurants. If wines are to be kept for years, storage conditions are paramount; on the other hand, very few wines in the world are intended for long keeping. The short of it is this: no need to worry about damage when moving a wine from shelf to fridge and back. By the way, the real danger is high heat rather than cold.
