There is something about a magnum that changes everything. The same wine, twice the volume — and yet it is not simply more of the same. Wine ages more slowly and more gracefully in a magnum, the greater volume of liquid relative to the amount of oxygen in the bottle giving the wine a longer, more measured evolution and a depth and complexity that the standard bottle, for all its virtues, cannot quite replicate. A magnum is a statement of intent: a wine bought to be shared, to be celebrated, to mark an occasion or simply to make an ordinary evening feel like something more. And J. Lohr Seven Oaks Cabernet Sauvignon from Paso Robles is exactly the right wine to make that statement with. J. Lohr is one of California’s most respected and long-established family wineries, and Seven Oaks is their flagship red — a Cabernet Sauvignon of real depth, character, and consistency that has been one of the benchmarks of Paso Robles winemaking for decades. Paso Robles is one of California’s most exciting and rapidly rising wine regions: a vast, sun-drenched appellation in San Luis Obispo County where the combination of warm days, cool nights, and a remarkable diversity of soils — from gravelly clay loam to limestone — produces Cabernet Sauvignon of a richness, structure, and complexity that stands comparison with the finest expressions of the variety anywhere in the world. The 2020 Seven Oaks is a classic barrel-aged Paso Robles Cabernet: layers of cassis, black cherry, and dark chocolate on the nose and palate, with the structure, depth, and persistence that come from careful oak ageing and the extraordinary diversity of J. Lohr’s vineyard sites. At £55.99 for a 1.5L magnum, it is the wine that turns a dinner party into a celebration.
