      Galbanum Pyrazine
      As with all pyrazines this is used in tiny traces – Galbanum Pyrazine at 0.1% in DPG is is deceptively nutty, but further dilution will reveal the strong green aspects of bell peppers, peas and galbanum. This material is present in the scent of coffee as well as parsnip, green beans and spinach as well as peppers, so it’s surprisingly versatile. Even at this dilution this is a very strong material that can enhance or contribute to green notes, give great diffusion and a very natural effect.

Galbanum Pyrazine
Odor: bell-pepper, peas, galbanum, natural, nutty, roasted
Use: As with all pyrazines this is used in tiny traces – Galbanum Pyrazine at 0.1% in DPG is is deceptively nutty, but further dilution will reveal the strong green aspects of bell peppers, peas and galbanum. This material is present in the scent of coffee as well as parsnip, green beans and spinach as well as peppers, so it’s surprisingly versatile. Even at this dilution this is a very strong material that can enhance or contribute to green notes, give great diffusion and a very natural effect.
