(Washingtonpost) - Air Force Col. Jay Ducharme cradled the bottle of 1996 Penfolds Grange in his arm as if it were a baby. He had come to the Ritz-Carlton in Georgetown with his wife, mother-in-law and brother-in-law to have the bottle assessed, tasted and re-corked. Penfolds’ chief winemaker, Peter Gago, and his winemaking team have re-corked more than 100,000 bottles of Penfolds wine over the past 20 years at similar free clinics around the world. Yet this was the first time Penfolds had brought its re-corking roadshow to Washington. Collectors were invited to bring in any Penfolds red wine 15 years old or older to have it evaluated, re-corked and, if Gago judged it sound, certified as genuine and in good condition.
