Dr Ray Beckwith OAM, will be remembered as Australia’s greatest wine scientist. He died peacefully in the Barossa Valley at the grand age of 100 on 7th November 2012. Ray work with "Penfolds" for most of his working life - 1935 to 1973. During his time there he observed “pH might be a useful tool in the control of bacterial growth in wine.” In plain terms Ray Beckwith discovered how to stabilize wine and protect it from spoilage. This discovery revolutionized modern winemaking both here in Australia and the rest of the world. This ground breaking work and other technical innovations underpinned the creative development of Grange Hermitage by Max Schubert. This interview is part of "A Year in the Life of Grange", a project Philip White and Milton Wordley are working on. The book and series of recorded interviews will be released in May 2013.
