Hawke's Bay's Gimblett Gravels winegrowing district lies on the ancient bed of the Ngaruroro River, which changed course in 1867 to expose the soils for possible viticulture. The relatively low altitude and proximity to the sea yet sheltered from the direct effect of the sea breeze, creates a temperate maritime climate. This location, altitude, and the stony soil's warming influence make it the warmest site in Hawke's Bay. The lack of excessive heat in the Gimblett Gravels is also a critical factor as it means the aromatic characters in the fruit, which contribute to the floral notes, are retained. The soils are composed of small to medium-sized greywacke stones interspersed with layers of silt and sand down to a depth of at least 40 metres. The stones on the surface absorb sunlight and heat during the day and then radiate heat at night, enhancing the vine's ripening capacity. Le Sol (French: the soil) is inspired by these renowned Gimblett Gravels. The vines are planted in the stoniest parts of the vineyard to a heritage clone of Syrah brought to New Zealand in the 1840s.
