Coonawarra
A cigar of red terra rossa soil over limestone, roughly fifteen kilometres long and almost perfectly flat, rising no higher than 127 metres. Cabernet Sauvignon grown on that strip is the entire reason the name travels.
Known for
- Cabernet Sauvignon

- Merlot
Why Coonawarra tastes the way it does
The terra rossa is a shallow red loam over limestone with the water table close beneath, and it stops abruptly at the edges of the strip. Cabernet Sauvignon grown on it is firm and structured with a recognisable leafy note. A few hundred metres off the red soil the wine is measurably different, which is why the boundary ended up in court.
January averages 20.5°C here and the growing season adds up to 1,556 heat units, which is moderate by Australian standards.
A short history
John Riddoch established the Penola Fruit Colony in 1890 and planted vines on the red soil. For decades the crop went into fortified wine and brandy before Cabernet's potential was recognised in the 1950s and 60s. The GI boundary was disputed for years before it was settled.
Coonawarra was registered as a protected wine name in 2003, which makes the boundary a legal definition rather than a marketing one.
What your house does to a bottle from Coonawarra
A bottle from Coonawarra ages at the rate its temperature sets, not at the rate the vintage chart says. Barello's model is the physical one: every 10°C above 13°C roughly doubles the rate, and at 25°C or more you are not ageing it, you are cooking it. Pick where you live and where the bottle actually sits.
Choose a city and a spot, and this line will tell you how much faster the bottle is ageing than it would in a cellar.
This is the same model that dates every bottle in Barello. Open the app to run it against your own wine. Or read how to store wine without a cellar, or the wine temperature chart.
