The 2005 Greenock Creek Alices Shiraz is the entry level wine, but you would not know it. With a whopping 17.5% alcohol, this is the most alcoholic wine I have ever tasted. Interestingly, the first sip is pretty good. The concentrated fruit covers the alcohol. However, by the end of the first glass, the alcohol dominates. The finish of the wine is sharp, and just not pleasant. It does not invite you for more, unless your aim is to get smashed. You get no varietal characteristics with this wine. It is not a port, but a wine dominated by alcohol.
Greenock Creek does not supply wines to the major Australian wine reviewers, and it is not hard to see why. Best to keep the mystique by keeping things secret.
