I have a small wine cellar in my basement for long term storage and a small U-Line under the counter unit in my kitchen in my home in Washington, DC.
In both cellars I have been losing 1/8 - 1/4" of wine in about 95% of my wine. There is no sign of leaks (no wine residue, etc.), the corks in the bottles I have opened that have lost some wine are perfect, a small ring around the bottom and the wine tastes exactly as it should.
However, I continue to lose wine without any explanation. The past two days I bought a bottle each day, put one in each of the cellars and marked the wine levels. Today I see that the wine has leeked once again roughly 1/8" - 1/4".
The specifics on the cellars are as follows:
The basement cellar measures 8 feet wide by 2 ft deep and has a Whisperkool 1600 in it. I built this myself per the Whisperkool instructions. Typical temperature range given by a bottle probe is 54.5 - 55 degrees with a hunidity range of 68 - 71%. The room has a temperature range of 58 - 60 degrees and a typical humidity of 48 - 51%.
The U-Line has no measurements other than the standard setting for temperature is between 55 - 60 degrees.
I have spoken to a number of wine retailers, friends with cellars, and even wine cellar contractors and no one has been able to offer a solution.
If anyone can help, it would be much appreciated.
