Aromatic features of the sample

This is the smell of freshly shelled, young garden peas and of their attractive green open pods.
It is a delicate smell, quite different from the sickly sweet, often metallic smell of canned peas!
2-Methoxy-3-isopropylpyrazine gives this vegetal earth scent present in garden peas and green coffee.
The smell of it is so strong that just a few drops of it could be detected in an olympic-sized swimming pool.

The smell of “garden peas” in coffee

It is always found in green or lightly roasted coffee but the longer the beans are roasted, the weaker it becomes.
It is more pronounced in the grinds than in the brew and seems to occur more in arabicas than in robustas.
It is vital to the balance of the overall aroma to which it brings liveliness and strength.

Coffee tasting

“I have found this aroma to be rather brash in the robustas of Brazil. It is very pronounced and easily recognizable in Ugandan coffees, as much in the robustas as in the arabicas. It is quite obvious in the Guatemalan arabicas.”
