Sylvie Gautreau is the 2nd generation owner of this well loved 77ha estate, and has produced an excellent wine within the vintage. This is not up there with the most concentrated of Sociandos, but there is liqourice, fennel, marzipan, spice, and juicy blueberry fruits. Tasted twice, each time clear that this is an enjoyable wine but also that even at this benchmark estate you can see the challenges of the vintage in the Haut-Médoc appellation. 48hl/h yield, Michel-Bernad Couanson consultant. Harvest September 27 to October 13.
Jane Anson, Inside Bordeaux, May 2022

Offering up aromas of dark berries, licorice, cigar wrapper and loamy soil, the 2021 Sociando-Mallet is medium to full-bodied, bright and concentrated, with an impressively layered core of fruit, tangy acids and a long, saline finish. The blend is 54% Cabernet Sauvignon, 44% Merlot and 2% Cabernet Franc, with late-harvested Cabernet Sauvignon, picked through to October 14, providing the heart of the wine.
William Kelley, April 2022

The 2021 Sociando-Mallet has a well-defined nose of tertiary black fruit, undergrowth and smoky scents. The palate is medium-bodied with grainy tannins. Not a powerful Sociando, but fresh and saline, tapering just slightly toward the finish.
