These two wines are from Riddoch Wines in Coonawarra and the 2015 vintage. Both are very good terroir wines.
The 2015 vintage in Coonawarra saw a very dry and warm spring which allowed for an even flowering and fruit set. Summer was milder however, and cabernet sauvignon was harvested at the normal time in late March to early April. So, in short, 2015 is a good vintage. Coonawarra Vignerons provide helpful vintage reports here for the region going back to 2000. Coonawarra cabs can of course age for much longer than 17 years, so if you have a reliable older source, please let me know.
Riddoch Reserve Coonawarra Cabernet Sauvignon 2015
This wine has all the hallmarks of a very good, well made Coonawarra cabernet sauvignon tasted in its youth. There are typical aromas of dark olives, earth, blackcurrant and cloves. The palate has long length, nice balance and well judged cedar and vanilla notes at the edges. This wine has that earthy, austereness of Coonawarra cabernet in its youth that suggests a long life ahead, and is so typical of the region. I’d buy this. (Alc: 14.5%, Region: Coonawarra, South Australia, Rating: Very Good, Would I buy it based on this tasting? Yes, Drink: now to 2027+, Tasted: July, 2017, Source: Sample)
Riddoch Coonawarra Cabernet Sauvignon 2015
This is the “little brother” wine, and is more approachable than the reserve. More violets and plush blackcurrants than dark olives and earth, it presents as a good wine that will suit more immediate drinking. (Alc: 14%, Region: Coonawarra, South Australia, Rating: Good, Would I buy it based on this tasting? Yes, Drink: now to 2023-2025, Tasted: July, 2017, Source: Sample)
