Chateau Leoville Las Cases has one of the longest histories in the Medoc. Leoville Las Cases was the property of some of the most notable and wealthiest inhabitants in France. The final royal family to own the estate is where the chateau draws its name from, the Lascases family.

The huge 98-hectare vineyard of Leoville Las Cases is planted to 67% Cabernet Sauvignon, 23% Merlot 10% Cabernet Franc. Though there are a few remaining vines of Petit Verdot. Interestingly, this shows an increase in the Merlot plantings over the past several years. The Leoville Las Cases vineyard underwent major replanting during the 1950s after the legendary frost.

The vineyard has a terroir that is mostly gravel with gravelly sand and gravelly clay in their soils. Today the vines average more than 40 years of age. However, they have old vines. The oldest vines are some of their Cabernet Franc, which are close to 90 years of age. The vineyard is planted to a vine density of 8,600 vines per hectare.

St Julien is located on the left bank of Bordeaux. The small commune has the highest concentration of classed growths. The Cabernet Sauvignon based wines that are produced here are structured, perfumed and elegant.
