Technically, there were two sightings in last week's episode, but one was so brief it barely counts. About 2 minutes into episode 6 entitled "For Immediate Release" Peter Campbell (Vincent Kartheiser) pours some Chivas for himself and Joan (Christina Hendricks). I've included the clip below even though the bottle wasn't really visible. A much better Chivas sighting took place at around the 16 minute mark when Peter pours from the same bottle. This is the 5th Mad Men scotch sighting so far, which isn't a lot considering how much alcohol is consumed on this show. This week's episode actually features a hilarious scene involving a bottle of Canadian Club.
I've been told by a few Scotch Cinema readers that there are more sightings throughout the series. Please let me know in the comments or on Facebook or Twitter if you find any. Click here to watch the scene.
