These are not the 1+ month results (double blind with side by side comparisons between Coravin-open bottle and new bottle), but these early findings bode well.
THE WINE: 2001 Grand Vin de Leoville du Marquis de Las Cases (St. Julien)
BACKGROUND: Bottle opened with Coravin up last Friday during an offline outside of Boston . . . approx. 10 ounces poured. Bottle subsequently stored in wine fridge at 56 degrees for last 7.5 days. Previous experience with other wine closures suggests this wine would have been undrinkable (or poorly drinkable)
FINDING: Late afternoon drink with a friend . . . the wine tastes fresh, bright, with no obvious change in taste/texture/characteristics.
Didn't intend this to be a tasting note, but just early evidence that the Coravin seems to be supporting its marketing claims quite well. Looking forward to posting the "double-blind" results at the end of Sept.
