Tasting note

Parallel's winemaker describes the 2019 Prima opening with cigar box, violets, crème de cassis, dark plums and French oak spice. The full-bodied palate layers graphite, forest floor and a hint of sweetness. The producer page also records a rich, earthy Cabernet with cassis, licorice, truffly earth, chocolate and tobacco, supported by ripe tannins, lively acidity and a long finish. Its structure is already approachable with air while retaining the concentration and balance for extended cellaring. The producer also records a long, chocolatey finish, with smoky wood and chewy tannin that should integrate with time.

From the cellar: pair with

Bone-in ribeye with rosemary butter

Rich beef meets the wine's full body and cassis, while rosemary echoes its herbal and forest-floor detail.

Braised short ribs with truffle polenta

Slow-cooked texture can absorb the Cabernet's structure, and truffle mirrors its earthy, graphite and tobacco notes.

Aged Comté with quince paste

Firm, nutty cheese complements the wine's oak spice and tannin, while quince lifts its dark fruit profile.

Service & cellaring

Serving Temp
Cellared guidance: serve around 60-65F (16-18C), slightly below room temperature, so the cassis, graphite and savory oak stay precise.
Decanting
Cellared guidance: open 45-60 minutes ahead, taste, and extend the air time if the tannin and oak remain tightly wound.
Cellar Storage
Cellared guidance: keep the bottle dark and stable around 55F (13C), away from vibration, heat swings and direct light.
