Our flagship wine that put JUSTIN on the map




Wine Society

About the Wine

In 1987, we made our first vintage of a wine styled after the famous First Growth producers of Bordeaux, created with the same uncompromising care as the Grands Vins of those venerable chateaux. Full-bodied with ripe black fruit and complex baking spice, this wine is amazingly ready to drink right out of the gate, and you can try a bottle or two now—but make sure to save a few to enjoy this wine as it continues to evolve after some time in the cellar.

Isosceles philosophy

“For more than 30 vintages, ISOSCELES has been our flagship wine and quality benchmark for this style of wine here on the Central Coast of California. A blend based on Cabernet Sauvignon supported by Cabernet Franc and Merlot, ISOSCELES shows why Paso Robles is such a great place to grow these varieties.”

Tasting Notes

Varietal Composition

  • % Cabernet Sauvignon
  • % Cabernet Franc
  • % Merlot




Bright with a dark purple/black core lightening to ruby/purple at the rim, with slowly forming, moderately stained tears on the glass.


Complex and attractively aromatic, showing very ripe cherry and black currant fruit followed by savory notes of cedar, pipe tobacco, vanilla bean, baking spice, and warm oak.


Full-bodied on the palate with ripe notes of crème de cassis and black cherry jam, with hints of red berry fruit on entry and vanilla, licorice, and baking spice leading into the midpalate, which shows complex savory notes of cedar, tobacco leaf, and leather. The lengthy and continually changing finish progresses from ripe black cherry fruit flavors accented by baking spice and oak notes to ripe chewy tannins and balancing acidity that adds depth and freshness.

The 2021 ISOSCELES is an exceptional wine that provides both an intensity and balance that allows it to hold its own when paired with deeply flavored dishes like a slow-cooked beef short rib braise, filet mignon, or venison steak.
