Where it is, October 2026

Too Young: holding until the full drinking arc opens in 2028.

In 2026, none of the five single-vineyard 2023 Cabernets in this portfolio have reached their stored drinking window, which opens in 2028 and runs through a peak from 2030 to 2050 before a hard decline projected in 2058. Because this bottling groups wines from Melbury, Vecina, St. Eden, Pluribus and Quella rather than a single site, the point of opening it now or waiting for 2028 isn't really about readiness. It's about tasting graphite, violet and mineral differences side by side before any one site's tannin structure has resolved.

The ‘23 Terroir Portfolio Horizontal.

BOND's Terroir Portfolio Horizontal lines up five single-vineyard 2023 Napa Cabernets, a 96-point vintage Wine Spectator rates Classic, still two years from the stored window opening in 2028.

Tasting note

Five glasses of dense, youthful purple-to-black Cabernet Sauvignon, one from each of Melbury, Vecina, St. Eden, Pluribus and Quella, the hillside sites BOND has built its single-vineyard concept around. The nose across the flight centers on concentrated dark fruit and graphite, with violets lifting through some pours more than others, exactly the variation a five-site portfolio exists to show. On the palate, fine tannin and real concentration run through every glass, but the mineral signature, graphite-driven in some, more floral in others, is what separates one site from the next. Each wine closes on its own note, which is the entire reason to taste them side by side rather than as five unrelated Cabernets.

The 2023 vintage

Napa's 2023 growing season followed a wet winter with a dry, cool and unusually steady stretch through summer, letting harvest stretch out as the crop sized up and surprised a number of vintners expecting a shorter window. Wine Spectator scored the vintage 96 points, rated Classic, with early returns showing wines carrying serious aromatic range and delineation. For a portfolio built to show five sites side by side, an even, low-volatility vintage like 2023 is a useful benchmark: with less weather swing distorting any one site's character, the differences between a graphite-driven pour and a violet-driven one trace more cleanly to terroir than to a difficult growing season.

About BOND

BOND is Bill Harlan's grand cru Napa project, a portfolio of single-site Cabernet Sauvignons drawn from a handful of rigorously selected hillside vineyards, prized for their terroir delineation and blue-chip status in Napa's upper tier. The five sites now number Melbury and Vecina, both established in 1999, St. Eden in 2001, Pluribus in 2003 and Quella in 2006, each bottled and priced on its own rather than blended together. The Terroir Portfolio Horizontal exists specifically to test that idea, tasting all five side by side rather than as one wine.

From the cellar: pair with

Plain dry-aged ribeye, no sauce

A neutral char lets the graphite and mineral differences between the five sites come through instead of being masked by a heavy sauce.

Simple roasted lamb loin, unsauced

Concentrated dark fruit and fine tannin across the set need protein and fat, but a plain preparation keeps each site's violet or graphite note distinct.

Aged cheddar or Gouda, no accompaniment

A clean, firm cheese tests each wine's tannin grip and mineral signature individually without a competing fruit or herb element.

Frequently Asked

What does 'Terroir Portfolio Horizontal' mean as opposed to buying St. Eden or Vecina separately?

A horizontal groups several wines from the same vintage to taste side by side, unlike a vertical, which compares one wine across different years. Here it means BOND's five 2023 single-vineyard Cabernets tasted together, so vintage, winemaking and grape stay constant and the differences trace to the site alone.

Are all five sites the same age?

No. Melbury and Vecina were the first two sites, planted in 1999, followed by St. Eden in 2001, Pluribus in 2003 and Quella in 2006, which completed the current five-site lineup. The portfolio format only became possible once all five were established and in production.

Should I open this at the same time I'd open an individual bottling like St. Eden?

The canonical CAI full drinking arc is 2028-2058. Within that arc, the peak window is 2030-2050. The full arc is the broader period the wine may drink well; the peak window is when it is most likely to show its best balance. Storage, fill level, cork condition, and preference can shift the decision. Taste before adding more air or holding the rest.

How should I handle decanting if I'm opening all five for a tasting?

Decant each bottle separately rather than combining pours, and give each 15 to 20 minutes since all five are still young and tannic in 2026. Taste them in the same order every time you revisit the set, since palate fatigue across five structured Cabernets back to back can flatten the differences you're trying to isolate.
