Glavya, the Scottish liqueur brand, is to link up with music-based social networking site Spotify to encourage people to create the longest ever play list of summer tunes. A competition will offer an ‘ultimate long-weekend’ to a European destination as prize. The competition is part of Glayva’s ‘Make Your Summer Last Longer’ campaign, running over the next four months to engage the younger end of the market to try Glayva in either its Gold or Blush long serves.
