it depends on how you store it. best way is to store in dark areas as light accelerates the growth of micro-bacteria (giving it that horrible smell)...
An unopened bottle has an indefinite shelf life.
Chardonnay is good for about 7 years unopened.
Most canned and bottled food items can be stored for a long time. But smell and then taste a tiny bit. If it is not "off", then use it.
Sort of. Although water itself cannot rot or "expire", over time a plastic bottle will leach hydrocarbons into the water (especially if the bottle is exposed to head or light). This will first make the water taste bad, and eventually render it undrinkable. Water bottled in glass will not have these problems.
If it's not evaporating yet then 1-2 days
10 minutes I believe.
Nothing can stay good if it never was.
for about a week
Read the label. It will tell you how long it will last. However, you can keep an unopened jar of jam for years and it will still be good.
In a very sealed non -porous container water is not evaporated.
Bottled water isn't itself 'bad' but the plastic on the bottle does dissolve eventually, so you can drink bottled water when it's relatively fresh, but after a long time (such as a year, six months, etc.) I wouldn't recommend it. Bottled water is not regularly checked by the FDA. Filtered tap water is more reliable and a whole lot cheaper.
Sadly, not long, especially if it's Amontillado, they're only good for like a month. Medium Dry sherries should be good for about a year.
