“Earthy, like green pepper”
Certified wine flavour standard used to train professional wine tasters to recognize and scale the intensity of earthy character.
2-Isobutyl-3-methoxypyrazine is contributed to wine by certain grapes as a desirable herbaceous, bell pepper varietal character. High levels of methoxypyrazines are associated with under-ripe grapes and the presence of wine stem material during extraction of the juice.
