title_body: Liquor bottle puzzle in Eavesdropper comic strip
upvoted_answer: We already have three bottles identified.  From left to right
  
  
  First bottle may be Gekkeikan Junmai Skye Blue Sake, suggested by crypdex
  Second bottle may be Bols Advocaat, suggested by OldPadawan
  Third bottle is Midori, identified by kazzie.
  Fourth bottle is Benedictine, identified by Yendor
  Fifth bottle is Choya Umeshu plum wine, identified by ellison in his answer
  Sixth bottle is Cointreau, identified by kazzie
  Seventh bottle is Antitoxin Absinthe in skull bottle, identified by me.
  
  
  
  
  The solution might be another liquor, Sambuca, from reading together the first letters of "Skye, Advocaat, Midori, Benedictine, Umeshu, Cointreau, Antitoxin".
