(Wine-Searcher) - A court ruling could see the whole of the US embrace interstate wine-buying by 2020.

The Supreme Court drama currently roiling the United States has an important consequence for wine lovers: the swing vote on ordering wine from out-of-state stores may be at stake.

Last week the US Supreme Court agreed to hear the case of Tennessee Wine & Spirits v. Byrd Clayton. At issue is whether or not state legislatures can create different rules for out-of-state liquor retailers and their own local stores.

A win could mean that, by 2020, most people of the US will be able to order wine from stores anywhere in the country. Currently this is only possible in 14 states. You can almost hear the sound of online-ordered grower Champagne (not "California Champagne") corks popping.
