I think it means this apple brandy can be served for many different occasions, purposes.

There is a tradition in Normandy of serving calvados as a digestif in the middle of the meal (a 'trou Normand'), but unless you have endured a succession of rich, creamy courses, you'll probably enjoy it more at the end. It makes good cocktails, too, for instance, Angel Face (equal quantities of gin, apricot brandy and calvados) or a Corpse Reviver, invaluable after the office party and made with equal quantities of brandy and red vermouth. It also makes a very good mulled cider mixed with cloudy apple juice and cider, spiked with cinnamon and cloves, and sweetened with brown sugar. And you can use it freely in the kitchen, particularly with anything appley. Importer James Rackham says calvados has particular appeal to women: 'Can one say that in the Guardian?' One can, James, but I know a fair few fellas who are big fans, too.
