The family who produces the Lui and William wines have been growing grapes in Toro for generations. They are a small family owned artisan winery located in the prestigious "pago" of Cascajera in the heart of Toro. The production of these handcrafted wines is very small with less then 2,000 cases produced annually. All fruit is estate grown on their 40 acres which is divided into small plots in Toro. The family owned vineyards are planted on the banks of the River Duero in gravel and limestone soils. The vines are ungrafted, many of which are more than 100 years old. The vines are taken care of by the family in the same way their ancestors did, without the use of pesticides or fertilizers. All organic matter is reused and the soil is plowed without machines. The vines are hand pruned and all grapes are handpicked.

The wines from Toro are brimming with tradition. Their origins date back to before the settlements of the Romans. The main grape of Toro is called Tinta de Toro, a synonym of Tempranillo, which produces some of Spain’s finest red wines. Old Tinta de Toro vineyards, planted with only about 1,000 vines per hectare (ha) account for 65% of the region’s vines. The rest is high quality old vine Garnacha and the white grapes, Malvasía and Verdejo. Most of Toro’s vineyards are planted at 600 to 750 meters above sea level. The climate is sunny and dry, the region gets only about half the annual rainfall of Bordeaux, but the vineyards are dry farmed, not irrigated. The soils around Toro are well-drained and often sandy, an environment not hospitable to the phylloxera bug and as a result, most vines are not grafted onto American rootstock.
