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. The result is a wine that helps to redefine Barossa Shiraz at the highest quality level.
Winter rainfall in the Barossa Valley occurred as infrequent, light showers which resulted in low soil moisture and vines were in water deficit at the beginning of spring. Early budburst was noticeable and windy conditions during flowering were, in part, responsible for variable fruit set and lower than average yields come vintage. Frost risks had to be managed by our viticulture team and growers. Warm days were dispersed
throughout October, November and in early January, contributing to an early start to the 2013 harvest and a relatively short, condensed vintage. Any January heat spikes were short lived and immediately followed by a mild reprieve. Dry and warm conditions, coupled with lower than average yields resulted in Shiraz showing strong, structural tannins, wines of great intensity and intense flavour.
