A bill--H.R. 5034--in the U.S. House of Representatives that could severely restrict consumers' ability to order directly from wineries has new life. H.R. 5034 could reverse five years of court decisions on direct shipping of wine and other alcohol, sparked by the Supreme Court's 2005 ruling that states cannot discriminate between in-state and out-of-state wineries in matters of direct-to-consumer wine shipping; the court ruled that the 21st Amendment, which ended Prohibition and put states in charge of alcohol regulation, does not trump the Constitution's Commerce Clause, which prevents states from restricting interstate trade. Wine Spectator associate editor Robert Taylor explains.
