"A superb Maison Bleue, the 2019 Hermitage La Maison Bleue seamlessly blends cherries and cassis into a purple mashup of fruit carried on rich, velvety waves of texture. Full-bodied and intense, it finishes complex and savory, adding notes of olive, clove and cedar on the long, luxurious finish. Already approachable, it should drink well through 2040."

"The 2019 Hermitage La Maison Bleue showed well, with impressive notes of ripe black fruits, iron, leather, and hints of camphor in a medium to full-bodied, fine, elegant profile. It’s well made and will benefit from 2-3 years of bottle age and evolve for 15+."

"The 2019 Hermitage “La Maison Bleue” from Caroline Frey at Maison Paul Jaboulet Aîné is a beautiful young wine. This is plenty ripe in this vintage, coming in at 15.5 percent octane, but not lacking in either precision or freshness. The fruit for the La Maison Bleue hail primarily from the lieux à dits of les Murets, les Signaux and Diognières, all of which lie on the eastern side of the hill of Hermitage. The wine is raised in entirely the same manner as La Chapelle, with the bunches destemmed and then elevage done in a combination of barriques and demi-muids for eighteen months, with no more than fifteen percent of the oak new in any vintage. The bouquet of the 2019 La Maison Bleue offers up a deep, complex and black fruity bouquet of cassis, black raspberries, pepper, smoked meats, a very complex base of soil tones, bonfire, an exotic touch of black tea, a discreet framing of cedary oak and a topnote of lovely spice elements. On the palate the wine is deep, full-bodied, focused and rock solid at the core, with firm, buried tannins, excellent focus and grip, impeccable balance and a long, youthful and very, very promising finish. This reminds me very much of the excellent example 1990 La Chapelle out of the blocks, but with a more buried structural chassis."

"Plenty of cloves and dried flowers with dark fruit, such as raspberries and blackberries. Some black truffle, too. Full-bodied with baked chocolate-pie and dark-fruit flavors. Full and warm at the end. Big, juicy wine. Give it a few years to come together. Drink from 2023."
