I think it has taken all twelve bottle and three years, but finally I thought this flavour was quite good. It fizzed on opening and had a dry & refreshing taste. Any mustiness was subtle (but not quite unnoticeable). The answer to horrible wine must be to leave it for several years before opening.
We started the wine on Wednesday night after WYSO (Mozart's 24th Piano Concerto - wonderful) and before Claire began her experiment to cure insomnia (basically don't try to go to sleep and when you do, sleep in a different bed to your husband). We finished it on Thusday, when Claire was feeling refreshed from a proper night's rest and I had been kept awake by Aggie wriggling, washing and scratching.
