> Beyond the initial resonance of the idea of sea-aging wine, there’s also a science to the process that Heude and his friends pegged with sheer intuition. Off the coast of Brittany, the temperature of the ocean floor hovers at 9-10C – the equivalent temperature of a deep wine cellar – while the water shields the wine from damaging UV rays. Plus, the twice-daily ebb and flow of some of the biggest tides in Europe mirror a technique used to age wine, particularly Champagne, known as remuage. The process of slowly tilting wine as it ages keeps the sediment from settling on the sides and bottom of the bottle and maintains the visual clarity of the wine. Pretty cool.
