The Cloister cocktail by Thomas Mario is a yellow and refreshing drink, perfect for spring days. The color might make it look fruitier than it actually is though, the cocktail is based on gin and grapefruit. Hence, this is rather a bittersweet drink, where the yellow Chartreuse and the simple syrup help balancing up these bitter notes.
1,5 oz gin
0,5 oz yellow Chartreuse
0,5 oz grapefruit juice
0,25 oz lemon juice
0,25 oz simple syrup
Shake with ice, strain and pour.
