You use a t-scoreâalso known as a Student's t-distributionâwhen you want to estimate a population statistic, such as the mean, or compare two groups of data. The t-score gives good results from small samples as long as the sample data form a bell-shaped curve when graphed.
The only fortified wine that can stand open any length of time is Madeira. That'll be good for 6 months. All the rest (port or sherry or marsala), depending on what it is exactly, only maximum, 2 weeks. After that, absolutely no good. And even 2 weeks is pushing it for some fortified wines. cheers, Bonnie.
Best Answer: How long a wine will age and improve depends on the tannic structure of the wine. Most big reds (Cabernet Sauvignon, Shiraz/Syrah, Zinfandel, etc) will be fine for 5-10 years in most cases as long as it is not exposed to extreme temperatures (hot or cold).hey will be wines with high Tannin content, and they will generally age for 5-6 years,with an outside age of ten years old.True collectible wines will continue to age (grow in flavor, body, mouth feel, and fruitiness) for decades when kept under ideal wine aging conditions,i.e. a wine cellar.
