When I installed AC in my wine storage room it lowered the temperature by 15 degrees F, or 9.4C in less than an hour and I could see tiny trails of bubbles in many of the bottles. However if the temperature never varies I can't believe much breathing occurs.The only concern is that corks are presumably breathable (the jury is still out on that)
As a wine lover, history buff and admirer of Thomas Jefferson, I found The Billionaire's Vinegar a fascinating account of the scams and scandals surrounding that wine(!) Recommended reading, especially for anyone who has any interest in collecting rare wines......Waxing is great for long term storage of wine. It will further slow down the aging/osmosis process. In fact, the most expensive bottle of wine ever sold (from a cache of 1798 Lafite once owned by Thomas Jefferson) was said to taste superb and the wax seal was credited.
