2018 Sena

Seña is the result of collaboration between the late Robert Mondavi and Chile’s Eduardo Chadwick, and is seen as THE icon wine of Chile for many. Part of this success and global recognition is due to the flamboyant promotional efforts of its creator, Eduardo Chadwick, a fifth generation family member of Vina Errazuriz. In particular, it was Chadwick's organising of international tastings and seminars that put Seña in the limelight, pitching his wine against the greatest First Growth and Super Tuscan properties and coming out on top. The Seña of today is an incredibly refined wine, and especially so in the climatically perfect 2018 vintage. Conditions in 2018 allowed the team to produce a wine of impeccable ripeness with more layers and nuances while maintaining freshness and the sense of "completeness" that has defined the vintage in Chile.

This is a very thoughtful Seña that shows unique aromas of warm earth, mushrooms and conifer, turning to dark berries and black olives. The palate is more glamorous with ultra-fine tannins that envelop your palate. Shows power and vibrancy at the end. Toned muscles. It’s a very intellectual wine that harkens back to the 2015. Blend of 55% cabernet sauvignon, 18% malbec, 15% carmenere, 7% cabernet franc and 5% merlot. Beautiful to try now, but better after 2023.

The 2018 Seña shows the fresher side of the Ocoa zone of the Aconcagua Valley through a Bordeaux blend of 55% Cabernet Sauvignon, 18% Malbec, 15% Carmenere, 7% Cabernet Franc and 5% Petit Verdot; there are small differences, but nothing substantial. As I've seen in other wines from the very complete 2018 vintage, the grapes ripened thoroughly and achieved more flavors and nuances, and the wines are slightly higher in alcohol (14% this year versus 13.3% in 2017, but in reality it's 13.8% ). But the wine seems to have more of everything. The grapes fermented in a combination of stainless steel and concrete vats and matured in new barriques and Stockinger foudres for 22 months, a similar formula as the one used for Viñedo Chadwick. This is a very elegant vintage of Seña, a year with a slow ripening so that the grapes achieved very good ripeness and full development of aromas and flavors, making the wine nuanced and complex, with depth but also freshness and finesse—floral and expressive. The tannins are very fine, polished and elegant, and the wine is long and complex, mixing the best of 2015 and 2016, coming through as a very complete year. It's still a little young and should develop nicely in bottle; it's approachable now, but if you can hold it a little bit more, it should be even better. This has to be the finest vintage of Seña to date. Comparing it with the Chadwick from the same year, there is more freshness and a little more complexity and clout coming form the cooler zone and the palette of varieties used that give more options to achieve more nuance. 100,000 bottles produced. It was bottled in February and March 2020.
