One of the most interesting areas for wines that for years were less than widely available in the USA was South Africa. Over the past ten years wines from the region have increased in availability and selection. Given their history, its nice to see how the recognition is taking hold there after 350 years.
In the USA finding the better SA (South African) wines is made easier via a long time merchant I personally have dealt with for years. Southern Hemisphere Wine and Spirits, in Huntingdon Beach, CA have great deals and great selections.
