Why do blueberries and beer share a fruity note?
Blueberries read as berry-sweet, beer reads as grain-bitter — yet both carry a suite of short-chain ethyl esters that pull the nose toward orchard fruit. The overlap is not accidental; it's biosynthetic.
All three esters form via the same esterification chemistry — in blueberries during ripening, in beer during yeast fermentation. When ethyl butanoate dominates at high OAV, the fruit signal overwhelms the matrix, which is why a cold IPA can briefly register as something closer to a berry than a grain.

OAV (Odor Activity Value) = concentration ÷ detection threshold. Numbers above 1 mean the compound contributes detectably to aroma.
