OXYGEN-PERMEABLE POLYETHYLENE VESSELS: A NEW APPROACH TO WINE MATURATION
Flecknoe-Brown, A
Flextank Ptv Ltd. in Australia introduced a new micro-oxygenation tank where gaseous O2 is directly injected into the wine through a sinter. This type of maturation vessel is made of gas permeable high-density polyethylene. It diffuses O2 from the atmosphere into the wine similarly as in oak wine barrels. Polyethylene types for wine used in large wineries were successfully tested in pilot-plant measure. Design factors for polyethylene 1000 l maturation vessels are described in detail. Preservation of wine structure during ageing is discussed, main advantages are, apart from others, summarized in detail, e.g. substantial labour savings, no loss of wine volume, better hygiene, easy cleaning , good control of wine maturation, etc. We recommend that you consult the full test of this article, which was published in Australian & New Zealand Grapegrower and Winemaker Australia, 2005, (494) 53-57
The seasonal character of harvests limits winemaking considerably, especially oenological research. Thus, conserving sterile musts during the whole year to carry out experiments is certainly a very...

Proteins occurring in wine originate from several sources during the winemaking process. Protein content in wines ranges from traces up to hundreds of mg/L, and may cause physical instability in wh...
