“Clé du Vin” This is a wine aging tool, often spoken of as a magical item among wine lovers, as it “simulates the matured state of wine years into the future by simply dipping it in for a few seconds.” ● Mechanism and Effects The round "alloy (patented)" at the tip of the muddler causes a specific chemical reaction with the oxidation components contained in the wine. • 1 second = 1 year: It is said that dipping the tip for 1 second in 100ml of wine will bring about a change in taste equivalent to aging the wine for 1 year. • Taste Changes: The sharp "tannins" characteristic of young wines become mellow, and the aroma opens up, increasing complexity. ● Main Uses and Purposes • Checking the drinking window: You can check "What will this wine be like if I let it age for another 5 years?" on the spot, the moment you open the bottle. • Measuring potential: Wines that do not lose their balance even after being dipped for a few seconds can be judged as "good wines that can withstand long-term aging." • Instant decanting: You can adjust hard wines that would normally require several hours of decanting to make them easier to drink in a few seconds. ● History and Reliability • The developers were a French oenologist (Mr. Laurent Zanoni) and the world's best sommelier (Mr. Franck Thomas), who collaborated over 10 years to develop it. • Currently, it is manufactured and sold by Peugeot, a long-established French manufacturer (famous for cars, but also top-class for mills and wine supplies), and is a highly reliable tool used by professional sommeliers in the field. ● Other • Semi-permanently usable: There are no batteries or consumables, and it can be used continuously as long as the alloy part does not wear out. • Compatible with all wines: It can be used for red, white, rosé, sparkling, and sweet wines.
