Using an unbreakable glass doesn't necessarily mean you have to sacrifice a lot of taste and flavor, but it does mean you might need to put in some extra effort. Try to match the shape of the glass to the type of wine: aromatic reds should have a larger rim; big and bold wines require a bigger bowl, and glasses for floral whites should be narrower.You also want to keep your wine chilled to the ideal temperature, so use an insulated glass and a chiller.In the case of reds, decanting can help smooth out tannins and activate flavors, even in cheaper bottles. Using a traditional decanter may not be an option when at a park or beach, but swirling frequently in the glass can help speed aeration. Pouring wine into a jug or travel container may be inelegant, but it does decant the wine nonetheless.
