have established preferences, but Millennials are more explorative and will consume a variety of beer, wine and spirits. As result of their lack of knowledge and experience they are not so committed to certain wine types, cultivars or trade names. In spite of that they tend to drink the same wines at home due to their parents’ or friends’ influence. If they do however socialise away from home, a variety of products are explored and consumed. Their innovative consumption is however not driven by social media, but rather by the attraction and prominence of the package. This is thus an ideal opportunity for cellars to attract new customers ( www.collagegroup. com ).

The mentioned disadvantages of glass bottles were the driving force for the development of bottles made from poli- ethylene terephthalate (PET). Given its weight advantage, gas and moisture proof status, resistance against alcohol and potential recyclability, it offers a popular alternative for glass bottles. It can also be made in the same capacities as glass bottles. It is especially popular amongst airlines as result of its weight and easy handling. A plastic glass can also form part of the packaging. “Bag-in-Boxes” or BIB’s were most probably the first alternative for glass bottles as wine packaging. It is used globally and

recommended as preferred packaging by certain wine monopolies. It is much lighter than glass bottles and the cost of packaging and transport are saved. As result of the contraction after wine is poured from it, air contact with potential, consequential oxidation is prevented and the wine has a longer shelf life than an open glass bottle. It is a comfortable, durable packaging, utilising space per volume better and also cheaper per volume. When it is filled care must be taken that an excessive air bubble volume does not remain in the bag, which can lead to oxidation. It is available in different sizes, with the 3 L BIB, equivalent to four 750 ml bottles as the most popular.

By integrating the foil and carton cover of the BIB, the container can even be simplified more and smaller volumes can be filled to meet the demand of individuals. It does not need a tap and wine can be poured directly from the container or drunk with a straw. It is available in different capacities ranging from 200 ml to 1 L. Tetra Pak packaging, which is the result of such development, is also used for other beverages. It promotes the informal consumption of wine by individuals. As result of the exterior carton of the BIB or Tetra Pak packaging, it is rigid to a certain extent. By removing the carton part, a foil bag with a tap, similar to a BIB tap could be developed and all product or label
