Under favourable condition, Riesling last a lomg long time. A bottle was opened in 1961 in London and was still drinkable after an amazing 420 years. Outlasted the best red Bordeaux.
I brought back 3 bottles and do intend to drink them all within the near future. Does anybody know if these Rieslings will be good? They're the "Wehlener Sonnenuhr Auslese" Rieslings and bottled in 1940. They even has a swastikas.
