I tried two new wines recently, and, surprisingly, I have teh same thing to say about both of them. The wines are Peter Lehmann Barossa Shiraz and Sumac Ridge Cabernet Merlot. Both of them taste mostly typical for their respective varieties, and they both start with a little "tangy zip" of something that I don't like very much. Unfortunately I don't know the word for the aspect I don't like, but you do become accustomed to that aspect after a few sips and then they are both perfectly serviceable reds. The unpleasant aspect may be cancelled out with appropriate food pairings, but I don't know how to do that.
