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.
Best Answer: Since sherry has a higher alcohol content than other wines, it will tend to keep longer. What happens once you open it is that you allow oxygen (from the air) into the bottle which starts oxidizing 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.
