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.
White wine and champagne should be stored in a refrigerator on its side. Red wine should be stored in a room that's just below room temperature, also on its side. Most people store red wine in their basement or cellar because that's usually the coolest place in the house.f it's a cork cork, then store it on its side to keep the cork wet. If you let a cork cork dry out, it will shrink and allow oxygen into the bottle. When that happens, your best bet is simply to dump it down the drain. You no longer have wine or champers.... you have vinegar.... and it's usually NASTY.
