Wine was on the docket at the highest court in the land today, as eight Supreme Court justices heard oral arguments in Tennessee Wine & Spirits Retailers Association v. Zackary Blair , the most important wine case to go before the high court in 14 years. At the heart of the case is a Tennessee law that mandates liquor retailers reside in the state for several years. But some hope the court will rule broadly, striking down restrictions on how consumers buy wine in multiple states.
