Any professional wine review can only be a snapshot of the current state of development of a wine. Since a wine develops or changes in the course of its life cycle (for the worse or for the better), a repeated or, if necessary, also repeated tasting is necessary. The forecasts made during the first tasting are checked, the changes are identified and documented. Since such a process is very complex, most do not wine critic for a re-or multiple tasting. For example, Robert does this regularly (for some of the wines) Parker and his team, or with the German wine internet platform Wein-Plus,
Usually, the producers hand over at least two bottles for tasting or become one if quality defects are found counter-bottle requested for counter-test (counter-test). This is to rule out the possibility that within a large batch of wines only one bottle may have this defect, i.e. the well-known phenomenon of one bottles variance given is. If the counter test is not required (which is usually the case), it goes to the archive. All wines whose development is worth tracking (i.e. mainly long-lived wines with a longer one to be expected durability, which are designed for a long maturation period) are then tasted again after a few years and the changes are documented. at Wein-Plus it is regulated as follows:
Every wine is described in detail and receives a forecast of the best drinking period. This also corresponds to the term that is often and used synonymously maturity (This is not "related to the reporting date", but extends over a longer period). This does not correspond to a clear shelf life information, but only provides information about the period in which a wine is likely to present itself most advantageously when stored normally. An indication of the year always means that it will present itself in good shape at least until the end of the specified year.
Many wines remain in good shape well beyond the date specified, but no further positive development is expected. Even with the greatest experience, this information always remains estimates, there are always positive and negative surprises, especially since the development depends very much on the respective storage conditions. However, there are ongoing tastings of older wines, most of which confirm the forecasts. See also under wine review and wine address,
