Charles Melton seem to produce good, flavoursome and well made Barossa grenache shiraz mourvedre (the blend this year is about 50/50 shiraz and grenache, with a touch of mourvedre). This wine had an aroma of plums, and a palate with notes of plums, pepper and substantial length (10 seconds plus). Very good. 88 to 89 points (and possibly higher).
