All sorts of delicate objects need to be given extra care to retain their original form and keep them to last longer.  The classical wine decanters have their own stories too and they have gone a long, long way to survive even up to this modern age.  Their use have not been eliminated particularly during formal occasions where different kinds of wines are served with matching ceramic and crystal decanters adding beauty to the wines and their taste.  Generally, these wonderful drinks are fruit extracts usually from grapes which have been fermented so the possibility of particles settling at the bottom of the original containers is there, thus the need for these drinks to be transferred to another vessel to exclude foreign matters found at the bottom of the bottle.
