“Earthy-potato skins, like potato skins or dug soil”
Certified water flavour standard used to train professional tasters to recognize and scale the intensity of earthy character.
2-Isopropyl-3-methoxypyrazine is formed by Actinobacteria in lakes, reservoirs and water distribution systems. It is a potent off-flavour with a very low flavour threshold. The compound imparts an unpleasant mouldy, musty note, reminiscent of potato skins or dug soil.
