Following are my tasting notes for the wines in question.
Grand Vin Castel, 2005: Dark toward inky garnet with firm tannins now integrating nicely with spicy and smoky oak. Opens slowly in the glass to show a nose and palate of black currant, blackberry and purple plum fruits on a background of generous Mediterranean herbs and near-sweet tobacco. On the long finish hints of citrus peel, anise and dark chocolate. Drink now–2013. Score 92. K
Grand Vin Castel, 2004: Super-dark garnet toward inky black, full-bodied, with deep and still-firm tannins integrating nicely with smoky and spicy wood and fruits. Opens with blackberries and chocolate, those yielding to currants and raspberries and finally to an array of licorice and tobacco that play on the palate. Long, generous and elegant. Drink now–2012. Score 94. K
Grand Vin Castel, 2003: Opens with a somewhat medicinal-iodine aroma, that yielding to licorice, meaty notes and spices. Dark garnet, full-bodied, with its tannins now integrated nicely and opening to reveal black currants and black and red berries, those with overlays of sweet herbs and green olives. On the long finish an appealing earthy-herbal note. Losing its fresh fruit nature and showing notes of maturity. Drink now–2010. Score 90. K
Grand Vin Castel, 2002 (Kosher Edition): Maturing nicely, its once-exuberant currant, cherry and plum fruits now more subdued though still pronounced, and yielding to the minerals and cedar that were once in the background. Full-bodied, with wood, tannins and fruits nicely balanced and taking on a more earthy-herbal note. Drink now. Score 90. K
