1979年，Chateau Mouton-Rothschild的菲利普男爵與加州葡萄酒巨擘Robert Mondavi合作，在加州的最精華產區Napa Valley成立了酒莊，並且命名為「一號樂章(Opus One)」；這是結合了加州的優異風土條件與法國的頂尖種植、釀造技術釀造出來的經典之作。自問世以來不僅成為加州最好的紅酒之一，也被視為世界級的頂尖美酒。從2005年份起，Opus One由新的釀酒團隊開始負責釀造工作，Robert Parker認為他們將Opus One引領到前所未有的高水準。
2018 Opus One名列這款酒開始上市以來最好的年份之一。相對於近年來加州常常是高溫乾旱的天氣，2018的生長季風調雨順，讓這個年份的酒質特別地高雅均衡。
本年份是84 % Cabernet Sauvignon、6 % Petit Verdot、4 % Cabernet Franc、5 % Merlot和1% Malbec。它聞起來帶有鮮活的果香如黑莓、黑櫻桃、黑李、甘草、鼠尾草、削好的鉛筆心、土壤等豐富複雜的香氣。口感飽滿圓潤不會過於厚重，成熟的單寧不生硬，漂亮的酸度構成極佳的均衡優雅感，香味也相當豐富複雜，以黑醋栗、香料等香料的香味為主，持續非常久。建議適飲期是2024到2058年左右。

Winemaker Michael Silacci commented that usually the blends are finished in January or February after the vintage. This year, with the 2019s, he was still tweaking the blend, but he did mention that this is "pretty close to the final blend."
Deep garnet-purple in color, the 2019 Opus One leaps from the glass with notes of Black Forest cake, Morello cherries, mulberries and fresh blackcurrants plus hints of licorice, wilted roses, Sichuan pepper and iron ore. Full-bodied, the palate is jam-packed with juicy black, blue and red fruits, framed by velvety tannins and background freshness, finishing on a compelling earthy/mineral note. Tasted as a barrel sample, this is a truly magnificent Opus One in the making!
