What sticks with you about this global blend of Napa and Southern Australian wine is the intense and transparent purple and blue fruit. Lots of blackberry and blueberry aromas with some stones and flowers, such as violets. It’s a very layered and intense wine with very refined, creamy and chewy tannins. Full and very impressive. Very Penfolds. Mouth-filling texture. It’s made mostly from Napa grapes and predominantly from Oakville and Diamond Mountain. About one-fifth is from South Australia. Aged in 80% new American oak and 20% new French. Try after 2026.

The first release of this new iconoclastic label, the 2018 Quantum Bin 98 is labeled as a "Wine of the World," although the AVA is the United States and technically 87% is American wine (Cabernet Sauvignon from Napa Valley), while 13% is Australian ("Grade A1" Shiraz from South Australia). The wine spent 16 months in oak, 100% new, 80% American oak and 20% French. In fact, the wine is made very much like Grange, in that it completes fermentation in new, mainly American oak barrels. Deep garnet-purple colored, it needs a good amount of swirling to unlock slowly emerging scents of chocolate-covered cherries, plum preserves, blueberry compote and cassis with fragrant suggestions of vanilla pod, violets, coconut, crushed rocks, pencil lead and clove oil. Medium to full-bodied, the generously fruited palate explodes in the mouth with ripe, juicy black and blue fruits, supported by firm, grainy tannins and a lovely burst of freshness, finishing long and spicy. It is mostly all fruit and American oak at this youthful stage, but I imagine that like Grange, its real appeal comes with bottle age. I would give it at least five years to allow the oak to marry and tertiary nuances to emerge, then drink it over the next 20 years or more. To manage expectations—this doesn't taste like Napa or South Australia. It doesn't even taste like the 2018 vintage here in Napa. It really is its own thing, which I suppose is the point.

The flagship wine in this range, the 2018 Cabernet Sauvignon Quantum Bin 98 is 87% Napa Valley Cabernet Sauvignon and 13% South Australia Shiraz. Blackberry jam, bittersweet chocolate, espresso, licorice, cloves and gravel infuse the 2018 with tons of character and complexity. Dense and opulent to the core, the Bin 98 possesses tremendous intensity. I would give if a few years in bottle to fully come together.
