Wines Paso Robles Justin Vineyards & Winery - Reserve Isosceles - 2021

Viniou Reviews

Justin Vineyards & Winery’s 2021 Isosceles Reserve is an iconic red blend hailing from the celebrated Paso Robles AVA in California. Crafted predominantly from Cabernet Sauvignon, with Merlot and Cabernet Franc harmoniously layered in, this deep, structured wine is assembled using grapes sourced from estate vineyards planted on limestone-rich soils. The 2021 vintage was marked by a relatively mild growing season, allowing for slow ripening, excellent phenolic development, and purity of fruit. After careful harvest, the wine matures in premium French oak barrels—often for upwards of 20 months—which brings added complexity, elegant tannins, and subtle notes of baking spices and toast. In the glass, the Isosceles Reserve reveals saturated violet color, aromatics of blackcurrant, wild berries, graphite, and dried herbs, with a palate that balances opulent fruit, integrated oak, and a long, persistent finish. This is a wine built for both early enjoyment and long-term cellaring.

Paso Robles is one of California's most dynamic wine-growing regions, nestled between San Francisco and Los Angeles, and heavily influenced by the dramatic temperature swings that define its climate. Hot sunny days ensure full ripeness, while cool nights—thanks in part to ocean breezes funneled by the Templeton Gap—preserve freshness and acidity. The region’s fragmented soils, particularly calcareous limestone in the western hills, are ideal for Bordeaux and Rhône varieties, offering both structure and distinctive minerality. Paso Robles’ history of winegrowing traces back to the Spanish missions, but the quality revolution has really accelerated since the late 20th century, positioning it as a hotspot for expressive, world-class reds.

For food pairing, the Isosceles Reserve’s depth and power invite bold dishes: think herb-crusted rack of lamb, dry-aged ribeye grilled over hardwood, or a classic duck confit. Regional Californian cuisine such as Santa Maria-style tri-tip also makes an excellent match, as do slow-braised short ribs with root vegetables or a gourmet burger with blue cheese.

For the best experience, decant this wine for at least an hour and serve at 16-18°C. This will soften the tannins and unveil the wine’s full aromatic palette. The Isosceles Reserve will reward careful aging, evolving beautifully over 10-15 years.
