Best's is one of Australia's traditional wineries with the current ownership in its 5th generation. It is well known for its cooler climate Shiraz. I tried their two major Shirazes from the strong 2005 vintage. 2005 Bin 1 Shiraz has a violet colour and tastes of dark fruit and spices. It has medium weight, but lacks some backbone. The tannins are quite strong on the finish. Overall, the wine is not that polished, but not a bad drop for the odd $26 per bottle.
2005 Bin O Shiraz is a step up. The blackcurrant and plum fruit has more sweetness and depth. However, the wine is also a bit harsh. It has a dry and gripping finish. It will no doubt be a better drink in a few years time.
Traditional wine making can be a strength, but it should incorporate some advances that clearly have been made. The holy grail for Australian Shiraz is to combine its fruit concentration and power with elegance and harmony. I would not select Best's if that was what I was looking for.
