Swiss food giant Nestlé has declined to comment on a report that it had offered to divest its Starbucks ice cream brand in order to gain regulatory approval for its proposed takeover of US-based Dreyer's Grand ice cream. The Starbucks ice cream brand, which Dreyer's licenses from the US coffee giant Starbucks, would be sold to CoolBrands International, reported the Wall Street Journal, citing lawyers familiar with the negotiations.
