Montepuliciano from Abruzzo, Italy

Tiberio Montepuliciano d’Abruzzo ‘Colle Vota’ 2019

The 2019 Montepulciano d'Abruzzo Colle Vota is intense, trading grace for power in this vintage, with a burst of dried black cherries, dusty sage, roses and Indian spice forming its bouquet. This splashes across the palate, spicy with ultra-ripe wild berry fruits that saturate, expertly balanced by a core of zesty acidity. The 2019 leaves a staining of primary concentration and grippy tannins, puckering the cheeks with youthful tension as salted licorice and balsamic spice notes fade. The 2019 C

Pinot Noir from Gevrey-Chambertin, Côte-de-Nuits

Domaine Louis Jadot Gevrey-Chambertin 1er Cru ‘Estournelles Saint Jacques’ 2018

Jadot have turned out a divine Estournelles from 2018. Burghound's note of it being an understated style rings true. Many 2018 from Gevrey-Chambertin are bold in nature. Here we see a delicacy that has it showing fine and elegant. Tasted blind you'd possibly look to another village. Deceptive it is, with considerable depth and length. Poise, flow and shape, with a perfume floating over delicious fruit. Jadot again showing a deft hand in crafting a sophisticated Pinot full of personality. April 2
