Riatta is a blend of sangiovese (50%), zinfandel (25%), and cabernet sauvignon (25%). The first glass was way in your face with the fruit in the sangiovese and zinfandel blowing out everything else. The sangiovese was bit tart for my taste, small tannins. A little sucking aeration in the mouth really brings out the fruit which is apparently what this winery is going for (or were, since this was the last batch before switching management).
A day opened let it mellow and finally let the cab show through more prominently. Still soft tannins. The sangiovese takes a back seat to the zin, so still in your face but without all the yelling.
