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.
Fortified wines are fortified by the addition of extra alcohol in the form of brandy or spirits to bring them up to an alcohol content of 18%â20%. Porto, Sherry, Madeira, Marsala, and Vermouth are all fortified wines.If the extra alcohol is added after fermentation, a dry fortified wine such as Sherry is the outcome.Adding the alcohol during fermentation results in a sweet wine such as Porto. Marsala is made from white grapes grown on the volcanic soil of the island of Sicily, Italy.Marsala has a burnt caramel flavor and is 18%â20% alcohol like all fortified wines.dding the alcohol during fermentation results in a sweet wine such as Porto.
