Everybody is so 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 possibly repeated tasting is necessary. The forecasts made at the first tasting are examined, and the changes are identified and documented. Since such a process is very complex, most refrain wine critic to a repeat or multiple tasting. This is done regularly, for example (for some of the wines) by Robert Parker and his team, or bein the German wine Internet platform Wein-Plus,
Usually, the producers hand over at least two bottles to be tasted or, if quality defects are detected, become one counter-bottle for the purpose of counter sample (counter sample) requested. This is to exclude that within a large batch of wines only perhaps a bottle has this error, so the well-known phenomenon of one bottles variance given is. If the counter sample is not needed (which is usually the case), it moves to the archive. All wines whose development is worth pursuing (ie mainly long-lived wines with expected long durability After a long period of maturation, they are then tasted again and the changes are documented. at Wein-Plus is this regulated as follows:
Each wine is described in detail and receives a forecast of the expected best drinking period. This also corresponds to the often and synonymously used term maturity (This is not "due date", but extends over a longer period of time). This is by no means a clear shelf life information, but only provides information on the period of time during which a wine is expected to be most advantageously presented. A year always means that he will present himself in good shape at least until the end of the given year.
Many wines stay in good shape well beyond the indicated date, but no further positive development is expected. Even with the greatest experience, these figures are always estimates, there are always positive and negative surprises, especially since the development depends very much on the respective storage conditions. On the other hand, re-tastings of older wines are ongoing, most of which confirm the forecasts. See also below wine review and wine address,
