Thanks for posting your thoughts - it is very interesting. I love Chartreuse as well and would love to compare with older bottlings.
What do you think of the VEP and Elixir Vegetal? I've considered ordering a bottle of VEP from my local liquor store, but I think I want to try it first before ponying up the $150. I found a bottle in a dusty liquor store a month or so ago, but the guy behind the counter wouldn't sell it to me because he didn't know the price. I am planning on going back to check on it, so maybe I can make a deal.
I can only speak to the VEP, but I find it outstanding. I mostly have it at restaurants, and I find I enjoy it more the longer bottle has been opened.
