Expiry dates on wines


OK the best by date is not exactly an expiry date, but consumer legislation has pushed for a time limit for everything. I can understand that drugs deteriorate and the sterility of various consumables for invasive procedures cannot be guaranteed for a long time, but some of the new expiry or best by dates really logic. Canned food can sometimes last a surprisingly long time, well past the supposed 3 to 5 years time limit used for setting best by dates (an interesting article about testing decades old canned food can be found here).

Wines are another puzzle. I have personally tasted a Madeira over 2 centuries old and it was wonderful, as were all those old wines of over 50 years I have tasted during a two week period in early summer of 2014. Coming back to this German wine, I found that I have different bottles of this Rieslings from this vineyard, all from the same vintner. This 2016 Spatlese has the same best before date of end of 2045 as a 2012 Auslese. However the longest life was assigned to the 2010 Auslese, which was reckoned to be good until the end of 2059! Vintage variations?!?
