Tasting notes below from Antonio Galloni of the Vinous:
"The Extra-Brut Cuvée No. 742, based on the 2014 vintage, is a gorgeous wine. In this release, the Cuvée seems especially marked by Pinot in both its flavor profile and texture. Dried pear, hazelnut, mint, chamomile and dried flowers all grace this rich, beautifully resonant Champagne from Jacquesson. Best of all, the 742 will drink well with minimal cellaring. The 700-series Champagnes are often superb; the 742 is an especially fine edition. The blend is 59% Pinot Noir (from Aÿ, Dizy and Hautvillers) and 41% Chardonnay (from Avize and Oiry). Dosage is 1.5 grams per liter." - 94 points
Tasting notes below from William Kelley of the Wine Advocate
"Based on the 2014 vintage and disgorged with 1.5 grams per liter dosage in July 2018, Jacquesson's NV Extra Brut Cuvée No. 742 continues the house's pioneering series of cuvées that employ reserve wines not in pursuit of a constant "house style" but merely with the aim of complementing each base vintage to maximize its potential. Wafting from the glass with a complex bouquet of walnut oil, dried white flowers, saffron, citrus oil and crisp orchard fruit, along with a delicate top note of fino sherry, it's medium to full-bodied, sapid and incisive, with superb concentration, racy acids and a long, resonant finish. I found it irresistible." - 93+ points
