Plantagenet’s vineyard estate has been carved out of the Great Southern's distinctive Marri Soils named after the massive native Marri, or Red Gum trees that grow there.

The soils are ironstone gravelly sandy loams over a base of clay or ironstone rock. The vineyard block sites were selected where good water drainage allows control over vine vigour, one of the most important determinants of fruit quality.

The fruit for the 2024 Three Lions Riesling was selectively machine harvested in the cool of the night. Free run (500L/T) and pressings separated and lightly fined before clarification and fermentation. Riesling-specific yeast strains are used to highlight the natural fruit characters of the vineyard—fermented cool (<15˚C) in stainless steel to dryness. The wine was racked post-fermentation, and light lees retained, with regular stirring. It was blended to taste with a light fining before bottling.
