I met some neighbours while walking today, and they stopped me and (because they'd read about my book in the local newspaper) asked me about keeping wines.
They said they wanted to know how long (unopened) wines and Champagnes would last before 'turning to vinegar', so I talked about aging etc.
Then they told me that they had a lot of wines which they weren't drinking fast enough and so, just before Christmas, they had taken several cases of the 'really old wines' to the council rubbish tip.
"How old were these wines", I asked
They were from the 2002 & 03 vintages.
