First swig of beer I had was when I was really young, pre-school age or so, Turns out my dad would **** out his smokes at the bottom of the bottle, and guess which bottle I pulled a drag from...
First taste of beer was when my grandpa gave me a taste of his "soda" when I was probably 5 or 6. First "real" beer was a Michelob before play practice my sophomore year of high school. It's the many dozens of beers in college that I can't remember quite as clearly.
