Had the 2014 version of this yesterday:
(Not my picture.)
One of the more enjoyable wine "discoveries" I have made over the past couple of years has been Semillon from Brokenwood in the Hunter Valley in Australia. It's not at all what you would expect from an Australian white if you haven't done much experimenting: it's high-acid and low alcohol and sees no oak: just a refreshing, characterful wine that's also pretty inexpensive.
The Sadie Kokerboom (which is a blend of Semillon Blanc and Semillon Gris from 80-year-old vines) is somewhat similar but bigger. There's more alcohol (13.5% -- still pretty low for South Africa) and more concentration, but it's still high-acid, mineral-driven, and refreshing. Just a lovely wine. Unfortunately, it's not cheap; but I don't regret spending the money.
I've really enjoyed the Sadie wines that I've tried. They all are unmistakeably New World, with lots of fruit, but they're never over-the-top or jammy or fat. The only thing that I dislike about them (other than the price -- all of them are relatively expensive here) is the wax seals over the cork: those make a real mess when you open them.
