Main Operating Conditions That Can Influence the Evolution of Wines during Long-Term Storage

Abstract

Nowadays, among all the possible wine packaging materials, an increasing use of polyethylene terephthalate (PET), multilayer Tetra Brik, and Bag-in-Box containers can be observed. Due to the fact that oxygen is counted among the primary factors which act on wine aging and degradation, a tight control of oxygen is critical during wine making and conservation. Wine protection from external conditions is strictly linked to packaging, which has the basic role to preserve the quality of wine during its evolution and aging. In this chapter the time evolution of different wines will be analyzed according to the storage conditions used. In particular, the following specific cases of study will be discussed: Case of study 1a, 1b, and 1c: influence of storage conditions (storage temperature, packaging material and volume of packaging) on the time evolution of red wine over a storage period of 12 months. Case of study 2: evolution of glass bottled rosé wine as a function of closure (cork stopper with or without aluminum capsule), storage position and brightness regime over a period 12 months.
