Top Bordeaux wine critic Robert Parker to retire

American wine guru Robert Parker, whose ratings could make or break Bordeaux vintages for the past 38 years, is to turn his power over to a successor on Sunday, his magazine announced. It will be the end of an era for the 68-year-old oenologist, who has however been retiring in stages, in 2014 leaving his British successor Neal Martin to rate “en primeurs” (futures) while continuing to evaluate top Bor-deaux vintages.
