Description and usage notes:

As with all pyrazines this is used in traces – Bean Pyrazine at 0.1% in DPG has a distinctively string-bean aspect, very green, though at this strength it still has the characteristic nutty odour of pyrazines, that disappears with further dilution.

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.

Please note that although pyrazines are commonly used in flavouring this product is not suitable for human or animal consumption.
