Analytical replicates are not independent vineyards. Brix alone does not represent aroma development, and these grape results are not a grain-whiskey maturation curve.
Oregon Pinot noir, 2002–2004; triplicate analytical measurements, tables PDF89–94 and plots PDF86,88,95.
Across three vintages, volatile families followed different grape-development trajectories. C6 alcohols generally declined, aldehydes peaked later, and free monoterpenes did not simply rise with sugar ripeness. Stir-bar extraction offered useful coverage but weak recovery for some polar compounds.

Evidence
Across three vintages, volatile families followed different grape-development trajectories. C6 alcohols generally declined, aldehydes peaked later, and free monoterpenes did not simply rise with sugar ripeness. Stir-bar extraction offered useful coverage but weak recovery for some polar compounds.

Annotation
Analytical replicates are not independent vineyards. Brix alone does not represent aroma development, and these grape results are not a grain-whiskey maturation curve.
Verification checklist
Verified as an accurate representation of this source, not an independent replication of its results.
