      Potato Pyrazine
      Naturally present in bread, some cheeses and chocolate as well as the potato it is named for, this is a surprisingly versatile material that is used as a component in modern cocoa flavours as well as coffee, bread and roast nuts. It can contribute all these notes to fragrance but, even more than most pyrazines it requires heavy dilution to be effective. Excellent in a gourmand when properly dosed.

Potato Pyrazine
Odor: chocolate, hazelnut, baked-potato, musty, natural, nutty, roasted
Use: Naturally present in bread, some cheeses and chocolate as well as the potato it is named for, this is a surprisingly versatile material that is used as a component in modern cocoa flavours as well as coffee, bread and roast nuts. It can contribute all these notes to fragrance but, even more than most pyrazines it requires heavy dilution to be effective. Excellent in a gourmand when properly dosed.
