      Bean Pyrazine
      Besides peas and beans, this pyrazine occurs naturally in coffee, grapefruit juice, potatoes and even some wines. Even at 0.1% this is a very powerful material that can easily dominate your blend, so use with caution in any blend where an original green-note is desired, or to add realism to grapefruit, wine and fruit accords.
