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.
up vote 2 down vote accepted. Marsala is a fortified wine, that is, a wine to which extra alcohol has been added. Therefore, you can store Marsala outside of the fridge, in a cool place (15-20 Â°C), away from direct light. In these conditions a bottle can sit there for several weeks/months with no obvious degradation, as you would expect for fortified wines.
