Fresh Firmenich Stock July 2024
I know that this is a few more £ than you can find on the internet, but that's mainly becuase rather than buying 180kg and letting it wallow (and develop sour butyric notes) for years,  I buy 50kg twice per year. The price at my end is higher, but the product is purchased in sync with production to ensure optimal freshness. 
 
Hedione is to jasmine what a Marquise diamond is to a raw uncut gemstone.
