I suspect the bottle on the right (vintage: 1977) may be the culprit. I don’t think I’ll bother tasting it to check.
Bottle on left (vintage: 1975) might Be worth tasting, but I reckon it’ll be borderline.
Have a decanter bottle read when you crack the aged bottle and transfer it as soon as you open the bottle. The crust aging wine throws on the inside of the bottle will taint the wine once it has been opened, decanting to another clean bottle or fancy crystal decanter will stop the wine from spoiling.dream4red wrote: ↑Wed Jul 01, 2020 1:43 am One sip is enough to know if it's good enough to drink or for the cooking pot. Go on, be daring.
We have a bottle of grandfather port that we have been sitting on since 1973, stored carefully, we will be cracking it when we have great grandchildren, so age wont bother us.
