Say goodbye to Indigo Imp Brewery's Winter Solstice. And say hello to Winter Soul. Indigo Imp, a production brewery in Cleveland, has decided to retire the Winter Solstice name because Anderson Valley Brewing Co. has a trademark on Winter Solstice. Instead of trying to fight over the name in court, owner and brewer Matt Chappel opted to rename his beer -- and retool it. "We're going to make a very similar beer higher in alcohol and with a little bit more bitterness," he said. Winter Soul is now available during Cleveland Beer Week.
