Claiming to be 10/10 with James Halliday, going to try and find out producer & information but Hunter Valley does produce good wines (though I may be biased as we live there, LOL).
Don't forget to go through a referral if you're not already registered to get the $25 credit.
Probably the James Estate Reserve Shiraz 2011 - Vinomofo has sold it before with the same technical details/rrp/"awesome for" categories etc.
