Also why the bottles are best stored sloping downward, to keep the bottom of the cork moist. I recently had the chance to taste 2 bottles of teenaged Canberra Shiraz back to back, identical other than one being affected by cork contamination which gives the wine a 'wet dog' smell & taste. This can be cured by making a ball of Glad Wrap and placing it in the decanted wine. Somehow this attracts the chemical responsible for the off taste and removes it from the wine.
