Julian Castagna is an erudite and totally committed disciple of biodynamic grapegrowing and winemaking. While he acknowledges that at least part of the belief in biodynamics has to be intuitive, he also seeks to understand how the principles and practices enunciated by Rudolf Steiner in 1924 actually work. He purchased two egg-shaped, food-grade concrete tanks, each holding 900 litres. They are, he says, ‘the most perfect shape in physics', and in the winery reduce pressure on the lees and deposit the lees over a larger surface area, which, he believes, will eliminate the need for batonnage. He has been joined by son Adam, who is responsible for the 400 dozen or so of Adam's Rib made each year, complementing the production of Castagna. Unfortunately wines were not received for the 2020 Wine Companion, the winery rating has been retained. Exports to the UK, France, Spain, Denmark, Korea, Hong Kong, China and Japan.
