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.
Some ice wines can last for 20 to 30 years.. Also impact the survival prospects of your wine is its quality, the vintage and the grapes used. The better the wine, the longer it will last. Ice wines, like most dessert wines, tend to store well because of their residual sugars and lively acidity, Kaiser-Smit says.
