The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test track. A tire graded 200 would last twice as long on the government test course under specified test conditions as one graded 100.
Most wine racks are designed to allow a wine to be stored on its side. The thinking behind this orientation is that the cork is more likely to stay moist and not dry out if it is kept in constant contact with the wine. Some wineries package their wines upside down in the box for much the same reason.
Fine or not, bubbly should be stored the same way all wine should be stored: away from light, heat, vibration and temperature fluctuation. If you have a cooling unit, keep it at 55 degrees F, with 70 percent humidity. If not, find a relatively secure spot, maybe in the corner of a closet. Youâll need to chill the bubbly down before serving, and the fastest way to do that is in an ice bath. There are a couple of caveats about sparkling wine storage.
