Depending on your taste, pour some grenadine into a beer glass and pour the shandy over it. Then stir carefully (so that the carbon dioxide does not escape). Depending on your taste, you can then add syrup.
You get a very refreshing drink that is especially popular in the south of France.
Tip: If you don`t have a cyclist at home, you can also mix Helles (Pils) with lemonade in a ratio of 3: 2.
