Vertigo is Booker's version of a GSM, similar to the Fulldraw, but slightly more power driven. I cracked a bottle before writing so I could really sink into it and this is what I got...blueberries and black fruits followed up by a long soft, pillow-like mid palate that leads into a lingering finish of beautifully ripe grapes. When choosing barrels to go into Vertigo, I look for ample stem inclusion in the Mourvedre and Grenache as well as a perfectly ripe Syrah. This GSM is usually ready to drink fairly quickly, but will soften a bit within a year.
