The abstract generalizes more broadly than the beta-ionone result supports. Do not say every bound norisoprenoid exceeds its free form tenfold. Potential released by laboratory hydrolysis is not the amount released in a finished beverage.
Same three-vintage Pinot noir setting; enzymatic/acidic hydrolysis rather than direct measurement of finished wine. Figure-only PDF102–103 contain monoterpene plots; PDF107–110 explain norisoprenoids and other compounds.
Hydrolysis exposed bound aroma potential with compound-specific and vintage-dependent development. Bound beta-damascenone substantially exceeded its free form, while the discussion reports bound beta-ionone below its free form. Vanillin and gamma-nonalactone potential increased during maturation.
