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.
We have an unopened bottle of champagne that is old. Can't say how old but it has been around for a while. When moving it I noticed some sediment in the bottom of the bottle.he reason I ask is that one reason wine goes bad is that the cork shrinks (when it's dry), allows air in, and the wine spoils. It sounds as though yours was stored standing up. However-open it and see. Smell it and, if OK, take just a sip.
