Wine Bottle - Research Paper Example From the discussion it is clear that  since the 17the century wine bottles have been closed by the traditional cork closures which are obtained by processing the bark of the cork tree. Portugal is the biggest exporter of the wine cork closures and its economy is highly based on this primary export. Wine bottle closures are highly important to seal the bottle so that the wine is not affected by the damaging property of the oxygen in the atmosphere although a very little amount of oxygen is still required to be trespassed in to the bottle which is helpful for the wine to reach its potential. The corks are not perfect enough to block all of the oxygen which serves the purpose but they are fallible too which can result in crumbling, breaking, leaking and also, forming the corked wine.  This essay stresses that  the cork closure provides the ceremonial tradition of opening the wine bottle with the popping action. Synthetic and screw cap closures are used as alternatives to the cork closures. The synthetic closures are not successful since they too pass the plastic taints to the wine. Screw Cap closures which are made of aluminium alloy casing which forms the outer layer of the closure with an inner lining of expanded polyethylene which air tights the bottle on compression. Screw cap closures are better wine closures than the cork ones and are also, comparatively expensive due to the material used in them but this expense is lower than the loss incurred due to the corked wines by the cork closures.
