Vodka maker Deep River Distillers is seeking approval to open a distillery in Rocky Hill, where the company would make its branded Krew Vodka. Deep River Distillers founder and owner Paul Grabek will appear before the Rocky Hill Planning and Zoning Commission May 19 to request a change of use for the Shunpike Business Center at 1275 Cromwell Ave., from office and warehousing use to manufacturing use. Grabek said town officials have been supportive of the plan in preliminary discussions. "It's very promising," Grabek said Monday, adding that he's had meetings with Rocky Hill's building inspector and fire marshall among others. "The town has been very easy to work with."
