The key is to stand the bottle upright for at least a couple of days before drinking; longer does not hurt. While decanting the wine, be careful not to include the bottom part, which includes sediment. Be conservative in making this judgement. Then follow the normal process.
Sediment and other particles in these wines can add to the complexity of flavour and this makes these wines often very attractive. However, consuming these elements is not helping, and often unpleasant. I have noticed that the enjoyment of these wines improves dramatically if you follow the suggested approach.
