2019 Ch Cos d'Estournel Blanc, St-Estèphe

This is incredibly long and refined with a compact structure and beautiful tension. It goes on and on. It’s full-bodied, yet tight and energetic. Lovely bitterness and brightness. Lemons, stones and limes. Flint, too. The grapes were harvested at three different moments. It’s beautifully constructed..

One of the best Cos Blancs for years, this is a real return to form, a great white wine that has presence and impact. Fantastic balance of rich, textured stone fruit with a fresh finish. You'll find salinity, slate texture, jasmine flowers and white pepper spice. It was a warmer year overall than 2017, and the white vines needed rain, which they got eventually but relatively late, meaning half the harvest was done on before the rain and the other half after some freshening rainfall, which perhaps accounts for this unusual but rather beautiful marrying of the two styles. Concentrated, powerful, balanced and complex. I love it. Drinking Window 2021 - 2035

The 2019 Cos d'Estournel Blanc, picked 16-23 September and seeing just 8% new oak, has more vibrancy and tension on the nose compared to the Pagodes de Clos Blanc, scents of orange blossom and yellow plums, the Sémillon very expressive. The palate is sharp and racy on the entry with green apple, melon, passion fruit and a slight tang of pink grapefruit towards the finish. Moderate length. Give it two or three years in bottle.
