Starting in the USA, the label is also increasingly displaying the words "unfiltered" on the label in Europe. This is to indicate that the wine was not filtered before bottling. It is not uncommon to dispense with the finer things in life. This is intended to prevent the loss of taste-forming aromas that cannot be completely prevented with these two processes. The prerequisite for this is a longer ageing of the wines. Particularly during barrel ageing, a natural sedimentation of the trub substances takes place, which are removed by racking (decanting) several times if necessary. It is a fact, however, that unfiltered wines usually have a higher deposit in the bottle. See also under vinification.
