Henschke is an Australian winery based in the Barossa Valley and Eden Valley regions of South Australia. The family-owned estate operates vineyards across both valleys, taking advantage of the distinct terroir each region offers for different grape varieties and wine styles.

The Barossa and Eden Valleys represent two of Australia's most significant wine regions, with the warmer Barossa Valley floor particularly suited to robust red varieties like Shiraz, while the cooler, higher-altitude Eden Valley provides ideal conditions for more elegant expressions. These neighboring regions share similar soils but differ in elevation and climate, allowing producers to craft wines with varying intensity and character from the same grape varieties.

Henschke's current range demonstrates their work with both single-varietal and blended wines. Their Mount Edelstone represents a pure Shiraz expression from the region, while Henry's Seven showcases a blend incorporating Grenache, Shiraz, Mourvedre, and Viognier—reflecting the traditional Rhône-style blending approach that has found success in South Australian terroir.

South Australia produces approximately half of the nation's wine and encompasses several of the country's most significant wine regions. Located in the southern portion of the continent, the state stretches from the cooler maritime-influenced zones near Adelaide to the warmer continental areas inland. The wine industry here dates back to the 1840s with German and British settlers establishing many of the foundational vineyards that continue to operate today.

The state's diverse geography creates distinct microclimates across its major wine regions. The Barossa Valley and McLaren Vale experience warm, Mediterranean-style conditions ideal for full-bodied reds, while the Adelaide Hills and Eden Valley benefit from higher elevations that provide cooler temperatures suitable for elegant whites and refined reds. Clare Valley is renowned for its limestone-rich soils and diurnal temperature variation, while Coonawarra's famous terra rossa soil over limestone creates unique conditions for premium Cabernet Sauvignon.

Shiraz dominates red wine production throughout South Australia, expressing different characters depending on the specific region and vineyard site. The state also produces notable Grenache, Cabernet Sauvignon, and GSM blends, particularly in warmer areas like Barossa and McLaren Vale. White varieties include distinguished Riesling from Clare Valley and Eden Valley, along with Chardonnay from cooler sites in the Adelaide Hills. The combination of old vine material, diverse terroir, and both traditional and modern winemaking approaches allows South Australia to produce wines ranging from powerful, age-worthy reds to crisp, mineral-driven whites.
