I shall answer this on behalf of my SJ relatives...
ESTJ: Very big social drinker. Goes out to bars frequently and mixes drinks at home occasionally. But I don't think he ever drinks alone. At one bar he has his own drink named after him. (I've had it, it's evil, it burns going down, and will make you soo... trashed.) Although he mostly drinks rum and coke. Eventually he wants to open his own tavern but so far hasn't been able to get a loan.
ESTJ: Not a big drinker. He strongly preferred bourbon. Was a believer in moderation but liked to watch his kids get drunk because he thought it was funny.
ISTJ: Angry, scary alcoholic who drank vodka like it was water. He often hid and lied about his drinking problem even though it was very apparent. Fortunately he's been sober for a year and says that quitting has drastically improved the quality of his life. He says that he doesn't see the point in drinking anymore and does seem a lot happier. Not surprisingly his dad was the ESTJ who liked to watch his kids get drunk.
