The proportions can vary from 1/4 beer to a 1/2 beer, with the rest being 7-up or Sprite. Just make sure you use a light (not dark) beer. It doesn't have to be a "lite" beer, though that would work too.
- 1 part beer (not a dark beer, but a light one, like a Bud, or Miller)
- 1 to 3 parts 7-up or Sprite
Fill a large glass with ice. Pour beer into the glass to the quarter-way to half-way mark, depending on the proportions you prefer. Top with 7-up or Sprite. Drink.
