The 2020 Le Petit Mouton De Mouton Rothschild showed beautifully and is certainly up with the top second wines out there. In fact, it’s better than the Grand Vins of many châteaux. Mostly Cabernet Sauvignon with smaller amounts of Merlot and Cabernet Franc, aged 18 months in 50% new French oak, it offers a rich, powerful, concentrated, and medium to full-bodied style as well as ample darker currant and cassis fruits, some tobacco and spicy oak, a great mid-palate, and outstanding length on the finish. It’s approachable today yet will benefit from 3-5 years of bottle age and evolve for at least two decades.

The 2020 Le Petit Mouton has less than 13% alcohol. It has an intense bouquet with black fruit, freshly-tilled loam, light estuarine scents and a touch of pressed violets. Very delineated and focused. The palate is medium-bodied with fine tannins, wonderful acidity and tension, very focused and mineral-driven towards the finish that is persistent. Graphite notes linger on the aftertaste. Superb.

The 2020 Le Petit-Mouton is fabulous. Dark red plum, blood orange, pomegranate, mint and cinnamon all build as this flamboyant, striking Petit Mouton shows off its considerable charms. Even with the high percentage of Cabernet, the 2020 is supple and quite soft for a young wine. Bright acids perk up the mid-palate, leading to the brilliant, sculpted finish. This has come together beautifully with élevage.

This delivers the expected glamour of Petit Mouton, although more reserved than in vintages such as 2015 or 2018. It retains a silk and satin touch to the tannins, and a ton of black cherry puree, spiced cocoa bean, coffee, liqourice root and campfire smoke. Deep, rich and enticing, the tannins are ripe but they have intent - this is a Petit Mouton to age. Think 8 to 10 years minimum. 50% new oak. Harvest September 7 to 24.

The 2020 Le Petit Mouton de Mouton Rothschild is a blend of 72% Cabernet Sauvignon, 24% Merlot, and 4% Cabernet Franc. Deep garnet-purple colored, it rolls effortlessly out of the glass with gregarious notions of blackberry pie, redcurrant jelly, and garrigue, plus nuances of crushed rocks, tar, and dried Provence herbs. The medium-bodied palate reveals very fine-grained tannins and plenty of freshness to back up the delicate red and black fruits, finishing on an earthy note.

The 2020 Le Petit Mouton benefits from the fact that the grand vin this year derives almost exclusively from the estate's core gravel terraces, meaning that many parcels that were included in, for example, the 2018 Mouton ended up in the Petit Mouton in 2020. Offering up aromas of cassis, cigar wrapper and violets, it's medium to full-bodied, fleshy and enveloping, with a broad attack and a layered, concentrated mid-palate.
