Sometimes, you just have to experience something, and forget about all practical considerations. That was the thought that drove me to the very exclusive environs of JAR Parfums in Paris. JAR is a perfume brand that is often spoken about in hushed tones, and which reeks of inaccessibility. The perfumes are the creation of one of the world’s most expensive, famous, secretive, and idiosyncratic jewellers, Joel Arthur Rosenthal, who simply goes by his initials as JAR. To really understand what the JAR perfume experience is like, you have to understand who JAR, the man, is first.
