Blackberry and black chocolate with mint, conifer and clove. Sweet tobacco, violets and flowers, too. Some graphite. Cool and complex. Full-bodied with ultra fine, dusty tannins and a wonderful, extremely long finish. Savory and refined. A classic-styled 2018. This needs time, but is so approachable and gorgeous. One of the best Insignias ever. Alive and changing all the time. 40% Stags Leap AVA. 87% cabernet sauvignon, 8% petit verdot, 3% malbec and 2% cabernet franc. Leave this for five or six years, but so wonderful now.

This impressive blend combines 87% Cabernet Sauvignon with 8% Petit Verdot, 3% Malbec and 2% Cabernet Franc, aging the whole for 24 months in 100% new French oak. Elements of cedar, sage, dried herb and underbrush meet rich red fruit and chalky tannins, with a dusting of cocoa throughout. Enjoy from 2028–2038.

The 2018 Insignia checks in as 87% Cabernet Sauvignon, 8% Petit Verdot, 3% Malbec and the rest Cabernet Franc, from a mix of vineyards (mostly in the southern part of the valley) aged two years in new French oak. It has an incredible bouquet of cassis, currants, dark chocolate, lead pencil, and tobacco, and while it's unquestionably Napa, it has a regal, structured, almost Bordeaux-like vibe as well. Full-bodied, perfectly balanced, and layered on the palate, with silky tannins, this quintessential Insignia is up with the finest vintages of this cuvée I've tasted and is in the same realm as the 1997 (the first vintage I bought for my personal cellar), 2001, 2002, 2007, 2012, 2013, 2015, and 2016. 17,000 cases.

The 2018 Insignia is a blend of 87% Cabernet Sauvignon, 8% Petit Verdot, 3% Malbec and 2% Cabernet Franc. The vineyard sources this year include: 30% Las Rocas (Stags Leap District),18% Yountville (Oak Knoll District), 13% Banca Dorada (Rutherford), 18% Suscol (South Napa Valley), 14% Home Ranch (St. Helena), 12% Las Rocas (Stags Leap District), 7% Barboza (Stags Leap District). It was aged for 24 months in 100% new French oak barrels. Deep garnet-purple colored, it comes storming out of the glass with powerful notes of blackcurrant cordial, stewed black plums and boysenberries, plus hints of cedar chest, graphite, menthol and wet slate with a fragrant waft of clove oil. The medium to full-bodied palate already demonstrates remarkable balance at this youthful stage, featuring a firm backbone of fine-grained tannins and bold freshness to support the tightly wound, crunchy black fruits, finishing long and spicy. 17,000 cases were made.
