Penfolds RWT Shiraz presents an admirable alternative to the multi-regional sourcing and American oak maturation that are hallmarks to Grange, expressing instead, single-region Barossa Valley Shiraz matured in French oak hogsheads
. The initials RWT stand for 'Red Winemaking Trial', the name given to the wine internally when developmental work began on it in 1995. 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 redefine Barossa Shiraz at the highest quality level.
