Located on the eastern side of the valley at about the same latitude as Saint Helena, Quella was planted in 1998/99 on light-colored volcanic tufa and river cobbles. Scents of crushed stone mark the nose on the 2019 Quella, accenting blueberry and blackberry fruit. It's medium to full-bodied, with juicy, mouthwatering acids and ripe, creamy-supple, tannins, making for a pleasant juxtaposition on the wine's lingering finish.

A barrel sample, the 2018 Quella has a deep garnet-purple color and opens with the most gorgeous perfume of violets, red and black plums, Morello cherries and cassis plus hints of iron ore and crushed rocks. The medium to full-bodied palate delivers lovely energy and tension, framed by fine-grained tannins and finishing with beautiful purity. Quella comes from a steep, southwest-facing vineyard in the eastern Vaca hillsides, just up from Joseph Phelps's winery and Denali Estate.

The 2017 Quella comes from a steep, southwest-facing vineyard in the eastern Vaca hillsides, just up from Joseph Phelps's winery and Denali Estate. Deep garnet-purple colored, it explodes with bombastic scents of stewed plums, boysenberries, crème de cassis and kirsch plus hints of black truffles, tar and damp soil. The palate is full-bodied and velvety, jam-packed with blackberry and plum preserves flavors with lots of savory nuances on the long finish.

Deep garnet-purple colored, the 2016 Quella slips seductively out of the glass with notes of warm black plums, blueberry preserves, licorice and crème de cassis with suggestions of wild sage, pencil lead, camphor and Marmite toast. Medium to full-bodied, the palate is like a tightly wound spring, featuring bags of black fruit and earthy nuances and a solid, grainy frame, finishing long and refreshing.

Bottled in early 2018, the deep garnet-purple colored 2015 Quella gives aromas of blackcurrants, black cherries and mulberries with touches of tobacco, new leather, iron ore and truffles plus a hint of tree back. The palate is full-bodied, muscular and laden with earth and mineral layers, finishing with persistent savory notes.
