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.
New wife, Marsala wines, in general are much like a good sherry. Loaded with alcohol (they are fortified wines) they ofter add a bit of sweetness to dishes that use them in the recipe, once you have burned off all that alcohol. Another good option, thought not to style would be to use a Pinot Noir from California.
