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.
Marsala wine has a unique taste for two reasons: the use of only Sicilian indigenous grapes and a complex winemaking process. Making Marsala wine is complex: 1  Marsala is fortified with brandy or neutral grape spirit usually made with regional grapes.
