Tooth and Co.
In 1976, control of Penfolds was acquired by Tooth and Co., a brewer based in New South Wales, which in 1982 became part of the Adelaide Steamship Company Group. In 1990, SA Brewing purchased Adelaide Steamship's wineries. Subsequently, SA Brewing was divided into three separate entities: the brewing assets retained the S.A. Brewing name, the wine assets were named Southcorp Wines, and the 'white goods' and other manufacturing interests became Southcorp, an Australian conglomerate.[9] It was also in 1976 that Schubert stood down from the position of Penfolds Chief Winemaker, a role that was passed onto Don Ditter.[8]
In 1977, Penfolds began what was to be an almost twenty-year association with Sydney-based rugby league team, the St George Dragons as the club's primary sponsor. This association saw the Dragons play five 'home' games at the Adelaide Oval between 1991 and 1995, with the 1991 game attracting 28,884 fans. The Dragons, with Penfolds as their sponsor, would win the Sydney premiership in 1977 and 1979, while appearing in the 1985, 1992 and 1993 Grand Finals. Penfolds ended their association with St George at the end of 1995.
Southcorp Wines became a part of the Foster's Group in 2005. In 2011, Fosters Group shareholders voted to demerge the wine operations from the brewing operations, and form two separate companies; Foster's wine business became Treasury Wine Estates (TWE). Headquartered in Melbourne, it was listed on the Australian Securities Exchange (ASX) and began operating as a standalone company on 9 May 2011.[10]
Since then, Penfolds operates two wineries: Magill Estate, at the base of Adelaide's eastern foothills,[11] and Nuriootpa in the Barossa Valley.[12]
In June 2012 Penfolds released a limited edition run of the "2004 Block 42" wine that was only sold in glass ampoules. The wine was labelled by the Huffington Post publication as "the most expensive wine directly sold from a winery in the world", as the winery sought US$168,000 for each of the ampoules. The glass ampoules were designed and hand-blown by Australian glass artist Nick Mount.[13]
