What makes a fresh apple smell like wine?
Apples and wine share a surprisingly deep chemical vocabulary — not because winemakers add apple flavor, but because fermentation amplifies compounds the fruit already carries in trace form.
The overlap isn't coincidence — fermentation selectively amplifies certain apple volatiles while suppressing others, which is why wine can read as orchard fruit even when no fruit was added. The chemistry was already there; yeast just turned up the volume.

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