Viognier has been a stand-out grape at recent tastings for Fiona Beckett.
I've long been a fan of the laid-back peachy characteristics. It varies massively in style depending on where it comes from.
My personal Aussie faves are Tahbilk, which is mentioned, and Rutherglen Estate's offering. I was surprised just how many good examples were coming out of the Rutherglen area.
