BREAKING DOWN 'Initial Public Offering-IPO'. IPOs can be a risky investment. For the individual investor, it is tough to predict what the stock will do on its initial day of trading and in the near future because there is often little historical data with which to analyze the company.
Sherry is an enriched wine, which increases its longevity. Still, once opened, the flavor quickly dissipates. An unopened bottle of sherry stored in a dark, cool place will stay fresh for 12 months. Once opened, cork the bottle tightly and store it in the refrigerator for one to three weeks, but no longer than a month.
(In a sealed bottle, there is enough fermentation going on to put a small layer of carbon dioxide on top of the wine.) You sherry will keep for four to six months once it's opened, but you should keep it in the refrigerator to slow the oxidation. You can probably use it after that, but it will begin to sour, and will have an adverse effect your food. Source(s):
