The nose is really fantastic with lead pencil shavings, iron shavings, blackcurrants and lavender. Full- to medium-bodied with ultra-fine tannins that run the length of the wine. Wonderful persistence and personality. Juicy and savory finish. Always classy and sophisticated at the end. Organically grown grapes. 71% cabernet sauvignon, 23% merlot, 6% cabernet franc and 1% petit verdot. Best after 2028.

A blend of 71% Cabernet Sauvignon, 23% Merlot, 5% Cabernet Franc, and 1% Petit Verdot, the 2020 Montrose is deep garnet-purple in color. It slowly emerges from the glass with profound notions of creme de cassis, chocolate-covered cherries, licorice, and roses, followed by suggestions of cast-iron pan and fragrant soil. The medium-bodied palate delivers many tightly knit layers of mineral, black berries, and floral notes with a solid backbone of firm, grainy tannins and lively acidity, finishing on a lingering ferrous note.

The 2020 Montrose was bottled in July 2022. The alcohol is 13.4%, a whole degree less than the previous year but with the same concentration (IPT is 80). It has a fabulous bouquet that delivers on all that promise from when I finally tasted the wine around a year earlier from barrel, a cornucopia of blackberry, bilberry, crushed stone, Indian ink and loamy/undergrowth scents. Very mercurial in the glass, it seems to shapeshift with every minute. The palate is medium-bodied with such a precise entry. This is far more detailed than either the 2019 or 2018, a symmetrical Montrose with unerring detail and mineralité, its silky texture belying the power underneath. This is unequivocally a brilliant wine and a benchmark in recent years. Contender for wine of the vintage.

This is up there with the best wines that I have tasted in the vintage. Beautifully balanced, classically refined but profound, delivering nuanced waves of cassis, blackberry puree, peony, pomegrante, mandarin peel, graphite, smoked sandalwood, incense. There is exceptional softness yet density to the tannins, such a confident structure overall and the build up on the tannins through the palate is so slow and careful that it is only at the end of play that you become aware of just how big a vintage it is. Clear ageing potential, easy to love, very easy to recommend. 12% press wine. Vincent Decup technical director. 40% of production in the 1st wine.

The Grand Vin 2020 Château Montrose is brilliant and unquestionably in the lineup of the truly greats from this château, including the 1989, 1990, 2009, 2010, 2015, 2018, and 2019. With an IPT of 80 and a natural alcohol of 13.4%, its deep, saturated purple hue is followed by quintessential Saint-Estèphe notes of pure cassis, graphite, tobacco leaf, acacia flowers, and loamy earth. Full-bodied, concentrated, and powerful, it nevertheless stays incredibly pure, elegant, and seamless, with perfectly ripe tannins. A blend of 71% Cabernet Sauvignon, 23% Merlot, 5% Cabernet Franc, and the rest Petit Verdot, is shines even today for its purity and balance, and it should be in the early stages of its prime drink window within a decade.

Surpassing the 2019 and rivaling the 2016 as this estate's finest vintage of the last few decades, the 2020 Montrose is a monument in the making. Wafting from the glass with aromas of violets, dark berries, licorice, loamy soil, black truffle and subtle spices, it's full-bodied, deep and layered, with a seamless, elegantly muscular profile, terrific purity and energy, beautifully powdery tannins and a long, resonant finish. It checks in at 13.7% alcohol, the same as the superb 2009, but it is even deeper, more vibrant and more complex than the 2009. This will be worth a special effort to seek out and only confirms Montrose's status as one of the contemporary Médoc's leading estates and a de facto first growth.
