Beerberries

It is my friend Paul's favorite time of the year because Red Brick Station has blueberry beer on tap. In fact, they drop a handful of blueberries into the beer before serving it to you. My question is how much alcohol can those blueberries really absorb in the 15 minutes or so that they are in the beer? I mean really. Certainly not enough to intoxicate even a 3 year old. Right?
