The key selection criteria are all about soil, the best sites consist of lateritic gravels over a clay loam base. The flagship Isa vineyard, just south of Margaret River provides the backbone of fruit. It's signature perfume is ever present in the wine, year in and year out. All the individual vineyard parcels are vinified separately. Following fermentation on skins and completion of malolactic, Stella Bella is treated to a luxurious selection of French tonnellerie's barriques for extended maturation. The length of time ageing is important for the complete integration of oak, fruit and tannins in the final wine. Bottling occurs in May of the second year, followed by several more months of bottle age.
