No, but Wine trading appears to be giving back more in return than the investment costs compared to Diamonds. At least according to your story. I can't imagine it's that difficult, but according to your story I might be wrong. A friend made a wine trading site btw. and tells me it's a lucrative business. Collecting the data was the hardest part he told. I wonder if there isn't a an authority where you can obtain the data instead of manually collecting it from auctions et cetera.
