Grgich Hills ages their Zinfandel in large oak casks so the flavors are well integrated but not overwhelmed by oak. The result is an irresistible mix of strawberries and raspberries with a hint of allspice that keeps evolving as the wine sits in the glass.
Nicely balanced between acidity and alcohol, this medium-bodied Zinfandel's forward fruit and soft tannins make it a great match with grilled meats, pizza and pastas with tomato sauce.
I couldn't tell whether the year or so since tasting a zin affected my impression but this really swallowed smoothly for me. I was less impressed with the rated Grgich fume blanc bought and tasted at the same time.
