      Condensate.

      It's water. Ethanol in water (mixture) severely reduces the surface
      tension of water, meaning water cannot 'bead'. However when this same
      mixture finds itself on the side wall or neck of a glass bottle, it
      becomes exposed to the air trapped in the neck, and the ethanol
      content evaporates, leaving behind the water fraction. The water then
      regains it's physical property of surface tension, and sticks
      or 'beads' on the glass.

      This is the same process that forms the 'tears' or 'legs' you see on
      the side of a glass of wine or spirits. The only difference there is
      that because the glass is open to atmosphere, more and more ethanol
      will evaporate, leaving behind more water, which collects in heavy
      drops like raindrops on a window, and trickle back down into the
      glass.
