GSM is Aussie for Grenache,shiraz,mourvedre . This is the best value of the 2012s . I don't normally drink on weds days but in the pursuit of research I am prepared to make an exception. I bought some lamb rump steaks. New way to cut it here. I will do them just with garlic,rosemary,salt,cbp & lemon. This wine is 54% grenache,29% shiraz ,17% mourvedre. I prefer this to some others that are a bit grenache heavy . Although the grenache in this is from vines over 50 years old so its good grenache. I paid $ 18 .I buy it every year except 2011 vintage.
