For those of you interested, Maynard was recently on
Wine Library TV going over a few of his bottles. Honestly, I can't say a lot about it, as I haven't been deeply interested in Caduceus/Merkin Vineyards/etc. for a couple years now. I did, however, enjoy watching the 2-Part interview by Gary Vaynerchuck with MJK and Eric Glomski, if only for the sheer energy Vaynerchuck displays and a good, solid source of info on Maynards wine-background.
There are a few interesting, brief asides throughout the interviews that relate to Tool/etc., but not a lot we haven't heard before elsewhere. Still, if you haven't watched this and are interested in what it is Maynard's been doing with his grapes, give it a look. I found it rather interesting.
