Josh: Have you checked with the wineries themselves? I know the Napa and Sonoma wineries have been hurting as of the last few months.
A couple of the big players, V. Sattui among them, have buyer direct programs and it might be worth a try to contact them and see where pricing is, especially given the downturn.
Not apropos to wine, but I’ve seen cigar pricing starting to show the signs of weak customer demand. A couple of the suppliers I deal with are starting to offer really good deals, and on premium labels.
