You will have to have some coordination and skill to earn this, but it is fairly self explanatory.
I do think it is worth noting that it does not count as a mistake if you miss a button after pressing
to drink beer. The button will still pass by the window and turn red, but you aren't penalized. It only counts as a mistake if you mis-time or mismatch an input.
Be sure to use the beer when things get pretty fast, but don't slow the game down to the point where you won't win the contest.
