Muscat/Moscato should be served chilled, but not ice cold.

Almost all examples are ready to drink when released and should not be aged, although dessert style versions can age for a few years. A general rule of thumb is fresher is better.  

Store bottles in a cool, dark place. While it is now common for wine makers to use plastic corks or screw-top closures which may be stored vertically or horizontally, those with the traditional corks should be laid on their sides to keep them moist.
