Back in the (17th-18th century) day, it was customary for sherry to be matured on trips to the Indies and back. Gonzalez Byass created an interesting experiment based on this historical fact, sending a barrel of 1990 Palo Cortado on a return trip to South America in 2018. After the journey, the wine was bottled and is now sold alongside a smaller bottle of the original stay-at-home wine for comparison. It’s clear that the well-travelled wine has evolved, gaining intensity and nutty, complex, oxidative maturity along the way. 96 points for the wine, but 100 points for sheer historical interest.
