Bipin Desai is a U.C. Riverside theoretical physicist who also happens to be the preeminent organizer of rare wine tastings, and he said, "" I've got a tasting coming up where we're going to serve the '47 Cheval Blanc. "" And it was going to be a double vertical — it was going to be 30 vintages of Cheval Blanc, and 30 vintages of Yquem.
