William and Elizabeth Oliver emigrated from Scotland, eventually settling McLaren Vale in 1841. Their homestead flourished, the sixth generation Olivers are one of the region's great winegrowing dynasties. For many years, they sold fruit to Penfolds, where it became one of the primary components to the mighty Grange. HJ is the ultra premium flagship Shiraz, purposefully crafted at the Boar's Rock wineworks. A vigorous wine offering immeasurable girth of fruit, great poise, elegance and the strength of character to evolve majestically.

The Taranga site overlooks McLaren Vale township. Along with good old gut feeling, which comes from years of knowing the vines and terroir upon which they are grown, state of the art computer controlled irrigation technology is employed to administer the optimum stress levels to the vine, translating into some of the world's finest Shiraz. Each block is individually nurtured depending on vine age, terroir and requirements of the winery. Most of Taranga's harvest is destined for other companies, only the pick of the very pick will find their way into HJ Reserve. The finished wine is matured thirty months in nothing but the finest, tightly grained, exclusively French oak barriques, half of which are completely new.
