When I was in yeshiva, there was no shabbos booze and weekday booze. Any booze I owned I drank anytime I wanted.
But my father has this mishegos, that he only drinks his scotch on shabbos. I have basically adopted this also, so now I need to have weekday booze and shabbos booze.
Now, I like bourbon just as good, so I would be fine drinking it on shabbos, but if I did, then I couldn't drink it during the week, and then what would I drink. I could drink rum, and I do (Belize Travellers One Barrel Rum), but you can't only drink one thing on 6/7ths of the days of the year.
So I'm drinking Elijah Craig right now. At 2:07E/1:07C/12:07M/11:07W. Which is a long time to drink for.
