Selecting a date upon which to begin harvest is arguably the most pressing, influential and troublesome decision required of any vigneron during the annual growing cycle. There is the romantic notion that growers arrive at this decision as a result of intuitive tasting of selected grapes picked randomly from a particular plot or row. Whilst intuition often proves invaluable, particularly in tough vintages, times are changing and the role of technology in tracking optimum grape ripeness is proving increasingly valuable. In no region are they pursuing optimum ripeness quite as comprehensively than in Champagne. I got to grips with just how this pursuit is evolving with Frédéric Panaïotis, Chef de Cave at Ruinart.
