Liked ours GINSTR Fizz if you can quite simply copy also at home!
You need in addition:
50ml GINSTR - Stuttgart Dry gin
30ml fresh lemon juice
20ml sugarcane syrup
1 shot soda (or mineral water)
GINSTR, lemon juice and sugar syrup with some ice cubes in a shaker give and shake hard. In a glass full with ice cube strain off and with soda pour.
