Following are my notes for those of the wines on your list that I have tasted.
Hagafen, Zinfandel, Napa Valley, 2005: A well-focused wine, medium-bodied, with soft, gently mouth-coating tannins and just the barest tantalizing hints of spicy oak. Opens with black cherry and sage notes, those going on to reveal ripe plum, licorice and mineral notes. Long and generous. Best 2009-2011. Score 90. K (Tasted 24 May 2008)
HaGafen, Zinfandel, Reserve, Moskovite Ranch, Block 61, Napa, 2004: Beautiful! Medium-dark garnet in color, medium- to full-bodied, with chewy tannins and generous wild berries, blackberries, and spices on a firm background, all of which open nicely in the glass and linger nicely. Long, and with a generously earthy-mineral finish. Best now-2009, perhaps somewhat longer. Score 90. K (Tasted 4 Aug 2006)
HaGafen, Zinfandel, Napa Valley, 2004: Firm and almost closed when first poured but given time in the glass opening nicely to reveal tempting aromas and flavors of wild berries, sage, a dash of black pepper and an underlying dusty earthiness. Drink now-2008. Score 88. K (Tasted 4 Aug 2006)
Herzog, Zinfandel, Special Reserrve, Lodi, 2005: Deep royal purple in color, medium- to full-bodied, with soft tannins integrated nicely and showing appealing spicy plum and berry fruits. Long and generous. Drink now-2009. Score 88. (Tasted 12 Mar 2007)
