Some
problems can be seen before the wine is opened. By old wine, sometimes
flakes can be seen throughout the bottle, maybe the wine has been
shaken too much, but if after leaving the wine for a while to rest,
it doesn’t look any better,then chances are, it won’t
taste too good.
Before opening a bottle of wine wether red
or white, it is worth noticing if the bottle isn’t as full
as it should be. If the wine seems to have evaporated, this could
mean that the cork has become porous and let air into the bottle.
The wine will probabally not be drinkable.
But there are problems one cannot see before
opening the wine. These make themselves known by the smell of
the opened wine. The most common problem is the cork, when the
cork is not leakproof and has let air in, then the wine smells
stale and corky. When a bottle has a bad cork it doesn’t
necessarily mean that all the bottles in that batch have the same
problem.
There is a scale to determine the quality
and age of a wine according to how full the bottle is:
High fill
This is the normal level at which wine fills a bottle. A high
fill after a wine has been kept many years, means that the cork
is ok and the wine has been correctly stored.
Into neck
This is also a good volume of wine and shows the wine has been
correctly stored.
Top shoulder
Lower than into neck, but if the wine is older than 10 years,
this is very acceptable.
Upper shoulder
This volume of wine is acceptable if the wine is older than 20
years. After such a long time the cork will have lost some of
it’s sealing qualities.
Mid shoulder.
This means that the cork is definitely not doing it’s job
properly, but if the wine is 30-40 years old, this is to be expected.
The quality of the wine though, will be affected.
Lower mid shoulder
This can only mean a problem with the wine, when the bottle has
lost so much of it’s original volume.
