Hello - I acquired a dozen + bottles of wine from an estate sale. They date from the 60's and 70's, are from Italy, Spain, and France, were stored in the owner's basement, and all seals are intact (except that some seals do have mildew stains). We opened up two bottles of Papillon red assuming these were of lesser quality and found they were bad. Bad, in that the color was muddy, taste was, well, yucky. So, our question is: what should we do with the rest of them? A bit of research showed us that some of the bottles are of finer vintages. Could they be ok? Can wines last this long? Would they be of any value? I can provide the names/years & photos if needed. Thanks for your help!
