95 Point Wine Advocate: The 2006 RWT Shiraz was aged for 14 months in 70% new French oak hogsheads. The winery describes its style as opulent and fleshy compared to Grange's muscular and assertive personality. Opaque purple in color, it offers aromas of Asian spices, beef juice, toast, blueberry, and licorice. Rich, fleshy, and round, it has plenty of underlying tannin, impeccable balance, and a long, pure finish.
Penfolds RWT Shiraz presents an admirable alternative to the multi-regional sourcing and American oak maturation that are hallmarks of Grange, expressing instead, single-region Barossa Valley Shiraz matured only in French oak. The initials RWT stand for 'Red Winemaking Trial', the name given to the project internally when developmental work began in 1995. Naturally, now no longer a 'Trial' !
RWT Shiraz was launched in May 2000 with the 1997 vintage. Its style is opulent and fleshy, contrasting with Grange, which is more muscular and assertive. RWT is made from fruit primarily selected for its aromatic qualities and fine texture rather than sheer intensity or power of flavour. The result is a wine that helps to re- define Barossa Shiraz at the highest quality level.
