Understanding Must Analysis
Technical Insights Before Harvest
As harvest approaches, we conduct detailed must analysis across all vineyard blocks at Napanook. Samples are evaluated weekly for Brix, pH, TA, and phenolic load, with particular attention to anthocyanin development and seed/brownness progression.
The comparative tastings provide early insight into aromatic precursors, mid-palate weight, and tannin grain, complementing the lab data. This dual approach allows us to calibrate picking sequences precisely—aligning physiological ripeness with phenolic maturity.
Tracking these trajectories block by block ensures that each lot is brought in at its optimum ripeness, safeguarding balance, freshness, and structural integrity.
