Legally this is not a Zinfandel. At 74% Zin, it's a point short of qualifying for labeling as such. Of course, Ridge has long treated Lytton Springs as a proprietary blend. In any case, it's also got 21% Petite Sirah and 5% Carignane.
Although the alcohol is higher than I'd prefer at 14.4%, it's not overly hot. To the contrary, it's got ripe dark fruit by the ton. Black cherry, blackberry, and plum. Enlivened with spice and black pepper.
The tannins are firm, suggesting potential for more extended aging than is the case with most Zinfandels. At the same time, however, it is drinking pretty well already. Even so, double decanting wouldn't be amiss.
