just dug through a bunch of photos on my phone and it was in fact the 2015. i can ask if they have received any new vintages. however, i believe all the listings for the '17 vintage in the states on wine-searcher are for grey market bottles judging by who is selling them.
I know some retailers that got in the 17 through their distributor
You’ll let us know who after you corner the market?
I snagged a single bottle while in WA on vacation for $95. It seemed to blow up after that release. I’ve heard they need a lot of time, so I’m waiting…as best as I can.
