There were the
obvious differences between the wines arising from clonal selection (most were made from the ubiquitous Gingin or Mendoza clone of chardonnay, which first arrived in WA in the early»70s, but a couple were made from more recently
imported French clones), vintage variation and sub-regional influence (wines from the cooler south of Margaret River tended to be leaner and crisper
than those from the warmer north).
