The 2015 Castagna Genesis Syrah, Castagna's flagship wine, is medium-bodied. It is certainly more delicate than, say, ten years ago, perhaps due to the rigorous biodynamic regime of Julian Castagna. This wine under cork already shows some development in the colour.
Red cherry and red plum fruits with some white pepper fill out the mouth nicely. This is a very pretty wine, perhaps a little too pretty. The shape is long rather than broad, with fine grained tannins. The satisfying finish is quite long.
I suggest to drink this wine now.
